March—April 2011 RASC NIAGARA CENTRE Volume 30, Issue 2 The Niagara Whirlpool President’s Report By Stan Sammy Inside this issue: Vice’s Report 4 “Discovery” by Kristin Carver 5 “Bucket List” by Darlene Marano 6/7 Secretary’s Report 8 David Perry Photos 9 Event Horizon 10 Members Observing Report 11 “Sun” by David Klooz 12/ 13 Masthead and Moon Phases We wish to advise that our club website will be up and running soon. Thank you for your patience. 14 During our many Public Observing Nights, the one question asked most is “What is the power of your telescope?” This is a valid question for most, since the telescopes advertised in the department stores list them by their magnification power (300x or 500x ). They seem disappointed when I respond telling them I don’t know. However I continue by explaining what magnification power is and that my 10’ scope is only at 80x or 100x. and very rarely would it need to be pumped up. Another question is ‘Do I need a telescope to become a member of the astronomy club?” My answer is “No equipment is required, all you need is a yearning to learn about the night sky. We will teach you how to become an amateur astronomer.” I hope that the following information will be of help to our new members and any one wishing to become a “Stargazer”. Welcome to Astronomy Astronomy is the oldest of the sciences. Human fascination with the heavens is timeless. Stargazing is intellectual as well as aesthetic. It combines the thrill of exploring new realms of knowledge with the delight of appreciating new spheres of beauty. Getting Started You can start exploring tonight! All you need is a little practical advice and this guide. There’s an infinite universe of celestial wonders to see and discover. You’ll be surprised at how much you can see with just your eyes. You’ll be able to make out the star patterns of the constellations, follow the phases of the Moon and watch the five brightest planets moving against the background stars. Meteors flash unexpectedly and artificial satellites drift slowly in and out of view. And don’t forget the colorful tapestry painted across the skies by the rising and setting Sun. Celestial Road Map Once you know a few constellations, the sky will always be a familiar friend. It will always be a familiar friend. You can learn the star patterns of the constellations with the simple star maps in this guide. Start by choosing the correct map for the season. You don’t even need to be out in a dark country location. The brightest stars that mark the constellations can be seen from many urban and most suburban locations. Sometimes a dark country sky can even make things harder for a beginner because there are so many stars that it’s hard to find the familiar patterns of the constellations! When you go outside to look at the stars, give your eyes a few minutes to adjust to the dark. Turn off as many lights as you can to reduce your local sky glow. A flashlight with a red filter is helpful. It will allow you to read your star map without destroying your night vision. Find north, south, east and west around your horizon. Hold your star map up in front of you and turn it so that the direction at the bottom of the map matches the direction in which you are facing. The lower edge of the map represents your horizon. The center of the map is your overhead point, the zenith. You should be able to match the pattern of stars in the sky with the constellations shown on your map. Once you have identified a star pattern like the Big Dipper, you can use it as a guide to find the next one. Congratulations! You’re on your way to a very rewarding hobby. Another kind of star map is the planisphere. It is a round (continued on page 2) The Niagara Whirlpool Volume 30, Issue 2 Page 2 President’s Report (continued) map printed on card or plastic that allows you to set the time of night and time of year, so it matches your current sky. Planispheres are good for determining what’s up in the sky, and when the stars and constellations rise and set. As you read along, remember that this guide only scratches the surface. For more information there are many good guidebooks available in your local library and bookstores. We can suggest a list of resources to help you get started. Software, such as Starry Night or Stellarium, can help too. Use it to help plan your observing sessions and to make and print your own customized star maps. Make Some Astro-Buddies If you are interested in astronomy and don’t already belong to an amateur astronomical organization, local or national, you should consider joining one. Not only will you make new friends and enjoy swapping ideas, it’s also the best place to get help and advice if you need it. In Canada, the largest national organization of amateur astronomer is the Royal Astronomical Society of Canada (RASC). The member clubs of these organizations hold annual and regional c o n v e n t i o n s a t wh i c h amateurs talk shop and exchange ideas. The RASC is composed of scores of local amateur astronomical clubs and groups, totaling thousands of individuals. We are the RASC Niagara Centre. As an astronomy club we offer workshops to help you get acquainted with the stars. If you own a telescope, but are having problems with it, there is no better place to go than an astronomy club. Take advantage of these gold mines of knowledge, experience and fellowship. The camaraderie of the night sky is a universal feature of astronomy clubs. There is no substitute for spending time with other people from different walks of life who all share the same love for the nighttime sky. Binoculars – a Good Start If you alread y o wn binoculars, put them to work. Be prepared for a pleasant surprise. They are easy to aim and use, giving bright, wide-angle images that are upright and not reversed (as is often the case with a telescope). Experienced amateur astronomers are never without binoculars, no matter what kind of telescope they might own. Binoculars let you see Jupiter’s moons orbiting around the planet – it is like watching a miniature solar system in motion. They provide wonderful views of the blasted surface of Earth’s Moon. Binoculars reveal the brighter star clusters and nebulae, too. You can see bright sparks of stars shrouded in wisps of faint interstellar gases. Others will appear as a faint glow of ghostly light. The Milky Way will amaze you with its glowing star clouds and knots of dark nebulosity silhouetted against the brighter galactic carpet. With your binoculars you can enjoy countless hours of travel in the stellar realms of the night sky. What Can You See in a Telescope? Nothing can compare with the feeling of making a direct connection to the cosmos! This is what a telescope can bring. Seeing for yourself the distant worlds of our solar system, ephemeral comets drifting through space, far-flung clumps of stars, and the ghostly glow of galaxies deep in the void, is a deep personal experience like no other. A telescope is a subtle space ship of the mind. The views will not look like the full color spreads in magazines and books. Such photographs need long exposures of many minutes or even hours. The human eye does not take time exposures. It cannot perceive colors in dim light. What the eye can do is see very fine detail in structure and contrast. Your telescope’s range is limited only by your willingness to be patient, to learn how to use it to its best advantage, and to learn how to really see what it is showing you. The Moon will be dazzlingly bright and sharp with a lifetime of detail to explore. The planets will look very small, even with high power. subtle detail will be revealed, especially during brief moments when our atmosphere is steady. Saturn’s rings and Jupiter’s bands are always showstoppers. The Moon and planets make rewarding targets from even the most light-polluted places. Stars are tiny and sometimes colorful pinpoints of light, no matter how big a telescope you have. Star clusters range from large, loose groupings of brilliant celestial jewels to faint and far away smudges of light at the limits of vision. Nebulae and galaxies run the gamut from big and bright to frustratingly faint. Patience and persistence will reward you with delicate detail in structure and contrast. The best views of nebulae and galaxies are from dark sky locations where there is little light pollution. A little knowledge of your target’s place in the grand scheme of the universe can make its observation a more meaningful one. All of your observing, with the unaided eye, binoculars or a telescope, will be easier and richer with the help of a good guide book, star maps and sky simulation software like Starry Night, Stellarium and an Astro Buddy. Choosing a Telescope for Astronomy Once you are familiar with the sky and are comfortable navigating around with binoculars, a telescope is the next step for many people. Choosing the best telescope The Niagara Whirlpool Volume 30, Issue 2 Page 3 can be challenging. Here are a few factors to help you make your decision: Aperture is Important The most important property of a telescope is its aperture, or the diameter of the telescope’s main optical element, whether it’s a lens or a mirror. Aperture affects the telescope’s light gathering power (which determines how bright objects will appear), and its resolving power (how much fine detail it can show). There are other factors to consider, but the larger the aperture, the more you will see. There are exceptions to the rule that “bigger is better.” One is portability. Large telescopes need housing in a permanent observatory or a strong back and a truck to get them to an observing site. The size of the perfect telescope is a balance between the largest aperture you want and the size you can comfortably handle. If you see yourself traveling with your telescope, portability and ease of set-up and use are the main deciding factors. Don’t Get Hung Up on Power The first question most people ask is “What is its magnifying power?” Magnification is not as important as a sharp image. If a telescope gives lots of magnification, but the image is a fuzzy blob, then the magnification is of no use. The maximum useful magni ficatio n fo r any telescope is about 50 times the aperture in inches, or two times the aperture in millimeters. This is about 100x to 120x with the smallest telescopes, which is enough to see such wonders as the rings of Saturn and cloud bands on Jupiter. Smooth, Solid Mounts Whatever kind of telescope you are thinking about, it will n e e d a s o l i d , smoothly-working mount. This requirement rules out most of the inexpensive and wobbly models. They can be wiggly and difficult to aim, and their poor optics produce distorted images. Ignore their claims of uselessly high power – you’re better off with a good pair of binoculars! The Cost Factor Budget is a factor in almost every telescope purchase decision. There are three major price-related pitfalls to be avoided: 1. Don’t buy a flimsy, inexpensive telescope at the mall with the intention of getting a taste of the sky and upgrading later. Many of those telescopes are so poor-quality and frustrating that they can turn budding astronomers off for good! 2. Don’t give up on astronomy if the telescope of your dreams is out of reach at the moment. There are many reasonably priced, high-q uality b eginner ’s telescopes that can reveal incredible wonders, while helping a novice define his or her observing interest. 3. Finally, if you are one of the lucky few for whom price doesn’t matter think twice before buying the biggest, most expensive telescope in stock. Many of the large, fully featured telescopes are also the most complicated, and are too much to grasp for someone still trying to find the Big Dipper! The Bottom Line Which, then, is the right telescope? That’s a decision that must be made individually, but the three best pieces of advice are: 1. The best telescope in the world will bring no joy if it is never taken out of the closet! 2. All else being equal, a larger-aperture telescope will show more in the night sky than a smaller one. 3. Buy from a company that’s knowledgeable about telescopes and astronomy, and who will support you even after your purchase (since you will likely have questions). Our advice is to choose a well-made telescope, of a design matched to your main observing interest and most frequent observing site. Make sure it’s a size that can be handled easily and used often, and you will enjoy a lifetime of awe and wonder under the stars! The Niagara Whirlpool Volume 30, Issue 2 Page 4 Vice-President’s Report By Dr. Brian Pihack Our guest speaker for the March meeting is Robert Godwin. Mr. Godwin will be presenting : “Science Fiction, Spaceflight, and Energy”. This gentleman is a very articulated speaker. You probably remember him from the last presentation that he gave at our meeting. What you might not know about him is that he opened his own record label, Griffin Music, which by 1992 would be voted best independent label in America by several major US newspapers. Over the next few years Griffin Music would release many classic rock acts' back-catalogs, of Anderson Bruford Wakeman and Howe, Motorhead, Thin Lizzy, Mike Oldfield, Olivia Newton-John, Hawkwind, Nazareth, David Bowie, and many other household names. In 1998 Robert was invited by his brother, Richard, to attend a celebration in honor of the crew of Apollo 7. During that event Apollo 11, astronaut Buzz Aldrin asked Robert to publish a book to honor his fellow astronauts and to commemorate man's first voyage to the moon. Working with advice from his friend, noted space-author, Andrew Chaikin, he launched a space book imprint, Apogee Books. In partnership with his brother, Robert he has subsequently worked with almost every surviving Apollo astronaut on his acclaimed book series "The NASA Mission Reports". Robert's space series has included contributions by Sir Arthur C. Clarke, Tom Hanks, Neil Armstrong, Buzz Aldrin, David Brin, Ro n Ho war d , Se na to r Harrison Schmitt, Eugene Cernan, Wally Schirra, Dave Scott, Walt Cunningham, Dr Marc Garneau, Eileen Collins, Bonnie Dunbar and many more astronauts and space scientists. Now if that does not bring you out nothing will !! Robert as a tradition also brings along a lot of books for sale at some really good prices. To read his full bio [from which I gleaned the above] please look up http:// www.apogeespacebooks.com/ A u t h o r _ B i o s / robert_godwin.html Lately I have been fine tuning a “home build project”: a flux field indicating magnetometer…… always wanted to be able to say that! Closest I will ever get to a flux capacitor. [Thank you Dr. Emmett Brown] Ah, did I just hear Dan F. smirk? I have taken the standard type o f magnetometer [used as a early warning indicator for auroras, added copper pennies to reduce the wave interference and nulling magnets to act as inertial dampeners.[Star Trek déjà vue !] It seems to be working very well. I have been able to reproduce findings that parallel the http:// www.ster nhimmel-ueb er ulm.de/aurora.htm site, but obviously at a much quicker rate, with more sensitivity, and best of all, specifically for this area. In the next issue of the Whirlpool I will include the plans for the one that I have just built, as well as the “New and Improved” model I am now working on. ….and now the best part. All but the power source and the rare earth magnets came from the dollar store. The power supply is a recycled solar garden light. Difficulty level, non existent. Problem: ….at the moment I first turned it on, the activity was very high. BUT, [as with buying a telescope and cloudy skies resulting] before I could calibrate the high end, the activity dropped, and has been very low to date. Hence I will wait until next issue to include the plans ! ...I have been fine tuning a “home build project”: a flux field indicating magnetometer…. The Niagara Whirlpool Volume 30, Issue 2 Fair Thee Well, Discovery! By Kristin Carver At 4:20 am two members of the Niagara Centre climbed from their beds to ready themselves for one of the most anticipated days of their lives. They quietly prepared themselves for the long day, constantly looking out their hotel window at the sky with silent prayers. After gathering all of their equipment, they made their way to their car for a one hour drive to the famous Space Coast. With a forecast of thick fog and haze covering the coastline, the members remained on edge while driving through the dense cover. Luck was on their side as the fog started to lift as their final destination crept closer. While driving down the Challenger Memorial Parkway, both travelers reflected on the triumphs and tragedies of the shuttle program. With smiles, they came upon their destination, Kennedy Point Park. Smiles faded to surprise at the number of people who were already set up along the Eastern edge of the park overlooking the water at a somewhat early 8:00am. They quickly gathered their equipment and found a small sandy spot along the waters edge with a clear view of the Kennedy Space Center. They laid out their towels and looked out over the water, squinting against the rising sun. Slight disappointment clouded their hope as they noticed the heavy haze close t the horizon on the opposite side of the channel. The Vehicle Assembly Building was barely visible and if they looked hard enough a small white smudge was off to the left of the enormous structure. They were told by another observer that that was the shuttle. With hopes that the haze would lift as forecast and with nine hours left until launch, they tried not to become discouraged. More and more people trickled into the park making the single row along the waters edge, spread to three rows in a little over an hour. There were people from all over the United States and parts of Canada, but the biggest surprise were two men who came from Sweden to see the launch. They were situated under a small tree, with a tiny telescope aimed at the shuttle, allowing them to get a close up view. After travelling almost halfway around the world last November to only be disappointed when the launch was cancelled, they were ready and excited to see it through this time. As time ticked by, many phrases became common in the park. Phrases like, “This is history,” and “Once in a li f et i me ,” wer e he ar d frequently, but not as often and as amusing as “The Bucket List.” Everyone knew that this day was the beginning of the end of a thirty year legacy. The sun rose higher in the sky and the haze began to disappear as Launch pad 39A finally came into view. With excitement everyone looked through their binoculars and high powered cameras to see the back of the tower and tip of the external fuel tank. It was hard to see, but the small speck of orange was still amazing none the less. The wildlife helped with everyone’s entertainment as they sat along the shoreline. T h e r e we r e m a n a t e e s swimming lazily, birds diving into the water and dolphins hunting along the shoreline. The children playing along a beach at the north end of the park had a big surprise when two dolphins swam close by. People gasped at another yet amazing sight as they waited. Clouds were not uncommon throughout the day, but a particularly thick section drifted over the launch site and decided to settle. With a couple of hours left until launch, Lady Luck made an appearance as the winds picked up and the clouds drifted away leaving the sky a crystal clear blue. Many spectators were wise enough to bring radios tuning into the NASA station and other newscasts. Everyone listened to the announcers talk about the history of the shuttle and the crew members on board. As they gave a detailed narration of the preparations and updated the listeners on the co u nt d o wn, t he unthinkable happened. At TMinus five and holding, a problem arose with the range safety command system. This system monitors the airspace and ocean traffic, enabling the shuttle to make a safe landing in the event that the shuttle needs to abort during its ascent. So as the launch window shrank minute by minute, the anticipation slowly turned to dread. The two weary travellers sat resting a reassuring hand trying to give strength to the other. Then as the window shrank to a Page 5 minute, they resigned themselves to the fact that the launch would be cancelled and prepared to pack up their camera gear. Just as the cameras were shut off, a voice announced on the radios, drowning out all other sound, “We are go!” A cheer rose up from along the coastline as the tension disappeared and excitement took over all in a mere second. As the countdown resumed, the anticipation mounted. And what would have normally felt like an eternity actually felt like seconds as cameras were pointed at the launch pad. A woman’s voice shouted out, “There it is!” and smoke started to billow out from under the shuttle. The gigantic craft slowly lifted away from the pad as people cheered and applauded. The celebration became louder as the giant orange flame, six times the length of the shuttle, emerged from the smoke showing the true power of mankind’s determination. As the shuttle shrank deep into the sky, the crowd became quiet as they watched in awe of Discovery’s last journey to the stars with silent prayers of “Godspeed,” “Safe trip,” “Good luck,” and my favourite, “Fare thee well Discovery and a safe return The Niagara Whirlpool Page 6 We have lift off…...Discovery is on it’s way! Volume 30, Issue 2 How to reduce the size of your Bucket List By Darlene Marano What are the chances of reducing your Bucket List by three items in a matter of 48 hours? Normally this would be a difficult if not impossible thing to do, however, I’m thrilled to say that I was able to accomplish just that. It started with the first thing that had been on my list since I was a little girl as I remember watching the Apollo launches and Neil Armstrong taking his first step on the moon on our family TV. It was thrilling and almost unimaginable to watch these events happen. I had waited so many years (and I won’t tell you how many) to see a launch, that sitting on the shoreline, viewing it live and listening to the familiar crackle heard from the rockets seemed surreal. It was not at all like the many Saturn V rockets and shuttle launches I viewed on TV and was in awe at the length of time it took for them to get into space. Watching it live was a whole new experience for me. I was shocked at the short amount of time it actually took for this spectacular 4.5 million pound vehicle to lift into the sky and rapidly disappear out of sight…nothing at all like watching it on TV. I feel truly fortunate to have had the opportunity to see Discovery’s final launch and I have my daughter, Kristin, to thank for almost nagging me to death about heading down for this event after our failed attempt last year. I finished off my Bucket List events with a ride in a NASCAR style stock car whizzing at 140 mph on an oval track (yes, I’m an astronomy and NASCAR geek) and by sharing a day at the Magic Kingdom, with just my daughter and I, and I can honestly say, I’m pretty happy. I share these shuttle launch photos knowing that everyone has seen ma ny, but considering we were 12 miles away and using standard lenses on our digitial SLR cameras, we were pretty pleased with the outcome of our MANY shots. Next item on the Bucket List...see Discovery at the Smithsonian:) The Niagara Whirlpool Volume 30, Issue 2 Page 7 The Niagara Whirlpool Volume 30, Issue 2 Page 8 Secretary’s Report By Philip Downey We have had nine new members join the club so far this year. They are Laura Curtis, Matthew Graham, Robert Hillier, Steve Lentinello, Barbara Lemieux, T a mar a Mai ur i, Mar k Michener, Don Mook and Gary Murphy. Please help me welcome them to the club at the next general meeting or public starnight. Our current membership total is 80. St. Catharines. Brian Pihack has offered the use of his office in Niagara Falls as a permanent address and mailbox for the club. This will save us $150 per year. Thanks Brian! We are giving up the club’s P.O. box in Niagara Falls, Ontario Our new address is: RASC Niagara ℅ Dr. Brian Pihack 4245 Portage Road L2E 6A2 We are working on a new design and format for the club’s website. Please let us know what features you would like to see on it. We could have sections or pages for news, archives, meeting minutes, weather, links to spaceweather, the clearsky forecast, whirlpool, rss feeds, a blog, twitter, photo gallery or galleries, calendar, light pollution, discussion forum and maybe other things I haven't thought of, so that's why I'm asking you. Please help me welcome Laura Curtis, Matthew Graham, Robert Hillier, Steve Lentinello and Barbara Lemieux to the club.

Got my van stuck a couple of times, but I wasn't giving up. (Maybe I have issues?) LOL! Stayed by myself for 6 hours. Occasional jumping-jacks, running-onthe-spot, and a thermos of coffee and Bailies will get you through any Arctic situation! Mmmm! I shot 2 1/2 hours of exposure on the Pleiades Cluster, and 2 hours on the Rosette Nebula. I will have them ready for the next Whirlpool. The air was dead-calm. I could hear for miles. The snow was crunchy/ squeaky. I saw 4-5 light pillars that night. Beautiful. A rewarding night of imaging and silence, for a person with APOCD. (Astro-Photography Obsessive Compulsive Disorder). I can't wait to do it again.

Our first two Members Nights have been snowed out, along with what seems like months of cloudy skies. The few clear nights we have had lately have been accompanied with howling winds. We just can’t seem to catch a break. We can only hope that things will start to improve. It can’t stay overcast forever. In March we will still be able to view Jupiter as it dips into the west in the early evenings. On the evenings of the 15th and 16th Mercury will be 2 and 2.5 degrees from Jupiter at twilight. You will need a good open view of the Western horizon as it will be quite low, approx. 10-12 degrees. Not a super easy grab, but see how many of you can observe it! On the 19th we will have the largest Full Moon of 2011 (The Worm Moon). Mercury will be at its greatest elongation on the 22nd, offering the best view for 2011. On March 26th we will be observing Earth Hour from 8 until 9 p.m. local time. Please join in and turn off all non essential lighting. I believe that they do this too early in the evening, as you really do not see the effect on the night sky. Still it drastically reduces energy use and every bit helps. If you are like me you may even want to keep them off longer. Diehards and early birds will find Saturn easily observable from about 11p.m. until sunrise all of March. In April, Saturn will be stealing the show. It will be observable all night all month. For anyone that wants to give it a try, Pluto will be in Page 11 Sagittarius, very close to M-25 in the early mornings. I have only observed it once before. I and a few others were at the CCCA and Phil Downey found it with the clubs 16” reflector. Hopefully we will get a chance to track it down again.

By David Klooz Not long ago, stars in binary or multiple star systems were thought to be the exception, not the rule. NASA now estimates that more than 85% of all stars may be part of a binary or multiple star relationship. While the Ancients (Vedic and Sumerian writings) made mention of our sun having a partner, there is certainly nothing in the current scientific mainstream literature that even hints at our star being part of a binary system. In order to examine the c ur r e n t p ar ad i g m a nd compare it to a potential alternative, it’s necessary to examine two areas of interest: 1 ) pr ecessio n o f the equinoxes; 2) and, the accepted frame of reference with respect to the current lunisolar model and an alternative frame of reference for a binary model. Precession of the equinoxes – The equinox is the first day of fall or spring when the exact point of equinox drawn by a line from the sun to the earth intersects the earth’s axis at exactly a 90 degree angle, so that night and day are of equal length, i.e., 12 hours. Precession of the equinoxes is then the slow backward movement of the equinox against the background constellations of the zodiac. It takes about 2,000 years for the equinox to move through each constellation, so that over a period of 24,000 years the equinox precesses, or moves backwards, through all twelve constellations of the zodiac. This cycle (The Platonic Year, The Great Year) was familiar to the Greeks, Egyptians, Vedic Indians and Mayan peoples, among others. Many of their great buildings were designed using precessional numbers, such as 72 (each star precesses 1 degree every 72 years). Lunisolar Model – This model uses only an internal frame of reference and supports the premise that precession is caused solely by lunar and solar forces causing the earth to ‘wobble’ on it’s axis, completing one such ‘wobble’ every 25,682 years. Binary Model – This model uses both internal and external frames of reference supporting the premise that precession is caused not only by lunar and solar forces acting on the earth, but by our sun’s curved motion through space around a common centre of gravity due to it being gravitationally bound to a companion star. In order to compare the models a number of areas of interest can be quickly compared, including comet paths, the Kuiper Belt, objects that precess, Sidereal and Solar Year time differences, and speed of precession. If we are in a binary system, the greatest issue facing this theory is what and where is the second star? Various scientists and teams of scientists have looked at a number of theories, including ‘Brown Dwarfs’, ‘Dark Stars’, ‘Modified Newtonian Dynamics’ and others. One of the most impressive studies is being conducted by Karl-Heinz Homann and his son Uwe Homann, directors of the Sirius Research Group near Edmonton, Alberta. Their research, over the past 15 years, implies that we might be in a binary or multiple star orbit with Sirius as our primary companion, and that there is an observable gravitational relationship between our solar system and the Sirius System. Their data also suggests that Procyon might also have a gravitational relationship with Sirius, which could explain why these two star systems seem to move together across the sky.
