I know many of you attended ScopeOut earlier this month; thanks to all who volunteered to make this event such a great success. Of course we all owe a HUGE Thank You to Dale Zoller, who has volunteered to organize ScopeOut for the past several years. Dale outdid himself this year, with some excellent new exhibits and activities. It is an enormous job to coordinate all the volunteers, exhibitors, and activities for ScopeOut, and the thoughtful effort showed. Thanks also to Denise Mustain who organized the dinner and caterer, John Barnes who made the nametags, and to all the other volunteers who helped with parking, registration, running the telescopes, the children’s activities, the hands-on science demos, the information tables, the gift shop, and all the other activities needed to make ScopeOut a fun and educational astronomy fair. I hope you will all be able to attend the October FOTO meeting on Monday, October 13 at 7:30. Our annual elections will be held that evening. We always need enthusiastic members with good ideas and energy, to help keep FOTO thriving. Please consider offering your time and talents to serve the Friends of the Observatory. Anyone over 18 years of age who has been a FOTO member in good standing for at least 1 year is eligible to run for office. Positions open for election include President, Vice President, Secretary, Treasurer and 2 of the Trustee positions. Frank Huss is heading the Nominating Committee; you can contact him at: fhuss3@aol.com. Nominations will be taken at the October meeting before the elections, or you can contact Frank before the meeting to nominate yourself or someone else for a Board position. Another great reason to attend our October meeting is to hear Jerry Black, Chair of the Ohio Chapter of the Mars Society, speak on the “Search for Life on Mars and Beyond”. Mr. Black is an excellent speaker and very knowledgeable on this topic. 1 We have two eclipses in October! There will be a total lunar eclipse on October 8 early in the morning (beginning at 5:18 a.m., maximal eclipse at 6:55 a.m., the Moon will be near the western horizon, and a partial solar eclipse on October 23 near sunset. We will be viewing the partial solar eclipse at Ault Park Pavilion. If you choose to view the eclipse from another location, be SURE to have safe solar filters to protect your eyes! Even when it is low on the horizon, looking directly at the sun can cause permanent damage to your retinas. The safest and most durable portable solar filter is #14 welder’s glass; we will be offering welder’s glass filters at the October FOTO meeting and in the gift shop for a special price of $4.00 for members. Astrophotography Workshop Third Thursdays February through November Next Session: Thursday October 16th, 8:00-10 pm Free for Cincinnati Observatory members. Space is limited. 513-321-5186. ScopeOut 2014 By Dale Zoller market. The Tesla crew spent the day surrounded by inquisitive guests discussing the innovative technology that will help reduce our carbon footprint. On September 13, the Observatory held its annual open house and science fair, ScopeOut 2014. To enhance our effort to push STEM (Science, Technology, Engineering & Mathematics) education, we had two exciting new additions to ScopeOut. This year's event began with the arrival of an R-44 helicopter courtesy of Stratus Helicopters. After landing on the parking circle, the helicopter was on display providing many visitors (young and old) their first opportunity to sit in a helicopter and learn about how these remarkable flying machines operate. Our second STEM star was a Tesla S provided by Tesla Motors located at the Kenwood Towne Centre. The Tesla S is the premiere all-electric car built in the USA and is considered to be one of the most efficient cars on the This year we transformed the "kids area" into the "Science Adventures" tent. We added more science-related activities including "Galileo" experiments (acceleration ramp, pendulum, tennis ball drop, etc.); cloud chamber; UC Physics Dept. demos; and an "inertial guidance" exhibit, which demonstrated how rockets are controlled in flight. We also had the usual activities for the younger kids, such as a scavenger hunt, art contest and face painting. A special thank you to FOTO-Teen Katie Burdette, who helped coordinate the activities. During the afternoon, the Mitchel telescope was set up for solar viewing. This was complemented by a solar energy display from Blue Chip Energy Services, showing you how to put the energy from our closest star to work for you. In addition, Observatory volunteer Kirk Schrotel displayed his 2 collection of solar gadgets. FOTO members Bob and Jerry Stenton once again had their “meteorite hunt” set up in front of the Herget Building and a lot of kids got to go home with a little piece of space rock. Adding to the excitement of our raffle this year was the new "Ball Drop" raffle. The top prize was a private night at the Observatory for the winner and 10 friends. Second prize was a gift certificate for a helicopter tour from Stratus Helicopters. About 5:45pm the helicopter took off from the parking circle and then hovered over the target area (a clearing on the west side of the grounds). The 160+ golf balls rained down on the target to the cheers of the crowd. The first and second prizes were won by FOTO members Sam Vessel and David Kuhl respectively. which made this exciting addition to ScopeOut possible. The evening activities began with dinner. This year's dinner was catered by Bella Luna Italian Restaurant. A special thank you goes out to Denise Mustain (and friends) who once again coordinated the dinner arrangements. And thanks to Lookout Joe’s for providing the “Observatory Blend” coffee. This year's keynote talk was presented by James Albury, Director of the Kika Silva Pla Planetarium. Of course, James's other job is cohost of the popular PBS series "Star Gazers" - along with our own Dean Regas. After his talk, "Engaging the Public in Astronomy," we opened the domes for evening viewing. Thanks to the clear skies, we had a continuous flow of visitors until 11:00pm. Finally, I would like to thank the members of the ScopeOut planning committee, plus all the volunteers, exhibitors and vendors who helped make ScopeOut 2014 a success! Did You Know…. A huge thank you goes out to Steve Paquette (and his crew) for their assistance and generosity Not all stars caught in the grip of a black hole are doomed to stay there, a few break away and are ejected from that galaxy. They’re known as high velocity stars as they travel at 1 to 2 million mph. FOTO Kids By Aashi Mital Eclipses are one of nature’s grandest events! And lucky for us that this October is going to be greeted by both a total lunar eclipse and a partial solar eclipse. It’s time to brush up on the umbra, penumbra and antumbra at the Cincinnati Observatory. Our next meeting is on Friday, October 3rd at 7 pm in the Herget Building. Don’t forget to bring your curiosity and to dress for the weather. If you have any questions, please email Aashi Mital at aashimital@gmail.com or Aaron Eiben at aaron@cincinnatiobservatory.org.

Schuck Joseph Sims Michael Sitko Lisa Stamm Michael Stoehr Desiree Willis Highlights of the September FOTO Meeting By John Barnes The September 8, 2014 FOTO Meeting, held at the COC, was called to order by President Michelle Gainey at 7:30 pm. The election season is upon us! We will elect new board members for their 2014-2015 terms at the October meeting. Frank Huss is the nominating committee chairperson. If you would like to serve the COC by holding an office, please let Frank know. We are planning something a bit different for this year’s December Members Appreciation Dinner - a pot luck meal / chili cooking contest. More to follow at October and November meetings. The speaker for the FOTO Meeting was Jeff Hutton. His presentation, “More Than a Telescope”, was the story of how he constructed his 16 inch f/4.3 reflector. In Jeff’s own words, “This telescope, like all major projects I’ve undertaken, bears for me attached memories of the period of its construction. More than most things I’ve built, recollections of Dick Wessling, who guided me in my growth in astronomy and who produced the primary mirror, among his last, are particularly poignant. It is used on every available clear night. I’m sure that the continued appreciation and use of Dick Wessling’s many instruments is just the kind of memorial he would like.” After a break the business portion of the meeting was conducted: Steve Rismiller has been helping us set up a webcam between the two buildings. He recently tried shooting from a refractor in the cone room but found tracking to be a problem. Future planning meetings will begin at 7:00 pm instead of the usual starting time of 6:00 pm. Tom East announced the Twin Lakes Star Party will take place from October 18 – 25 at Kentucky’s Pennyrile State Park. This could be an opportunity for members of the COC to make connections with fellow amateurs who will have the good fortune of being in the path of totality for 2017’s solar eclipse. The next members meeting, Monday, October 13 at 7:30 pm will feature, in addition to the board members election, a presentation by Jerry Black regarding the chances of life on Mars. History of the Observatory October 12 & 26 Drop in anytime between 1-4 pm The 1904 Clark Telescope $5 per person suggested donation. Free for members. Group tours by appointment. Did You Know…. Guysers on Enceladus spew out 100,000 times more water than Yellowstone’s guysers. 4 Mt. Adams Walking Tour By Aashi Mital Welcome to Fall! We’ll be enjoying the lovely weather with a private historical walking tour around Mt. Adams on Saturday, October 4th at 1 pm. The group will arrive at Mt. Adams Bar & Grill (938 Hatch St. Cincinnati, OH 45202). It is $10 per person (cash only). Reservations are required and the deadline to sign up is October 3rd by 5 pm. The only way to make reservations is by signing up at the monthly FOTO members meeting or emailing Aashi Mital at aashimital@gmail.com. We’ll be visiting the Immaculata Church, the location of the annual Good Friday Pilgrimage and learn where the US Weather Bureau and American Astronomy were born. Rookwood Pottery, the Passionist Monastery, Cincinnati’s oldest Irish pub and the site of the Mount Adams Inclined Plane Railroad are also on the list! This is going to be a 90 Minute Walking Tour with stairs, moderate grades, etc., so wear comfy clothes and shoes (There’s a reason why Cincinnati is called the “San Francisco of the East.”). Bring your cameras, your adventurous spirit and be prepared to enjoy yourself. FOTO's October 2014 Meeting By Dave McBride October is stacking up to be a fantastic month for sky watchers – with the “Hunters Moon” on October 8th being a Total Lunar Eclipse. The eclipse will be visible throughout most of North America, South America, eastern Asia, and Australia. Following that will be the Draconids (8th & 9th), Orionids (22nd & 23rd) and finally the Partial Solar Eclipse on the 23rd. The partial eclipse will be visible throughout most of North and Central America. We are all hoping for continued crisp, clear viewing conditions. Add to that, on October 13th, Jerry Black will be the presenter at our 7:30pm membership meeting. Jerry is the current Chair of the Ohio Chapter of the Mars Society. He will be speaking about “The Search for Life on Mars and Beyond.” The primary emphasis of Jerry’s talk will be on the search for past and present life on Mars, however the search for life on other planets and moons in our solar system – and beyond – will also be covered. Over the ages humankind has been pondering the question: Are we alone? We are fortunate to be living in a time when our robotic probes and telescopes have progressed to the point that we have the potential to answer this question. If life is common in the universe, then there is an excellent chance we will find proof of extraterrestrial life within the next 20 years. The chase is on with robotic probes within our solar system, with telescopes analyzing the constituents of the atmospheres of exoplanets, and with the SETI efforts searching for extraterrestrial intelligence. This talk will cover the latest developments in this search. On November 10th our program will feature Terry Flesch telling us about his private observatory – its design, construction and use. Terry’s non-technical presentation will help everyone relate to his personal experience. Information about our December volunteer appreciation dinner will be coming next month. Watch for it too!

With that being said, it’s time to get the A2Z Astronomy classes rolling once again; there has been just way too much Astronomy going on to just sit back. Polarization observed in the Cosmic Background, oops, no, wait a minute… maybe no polarization in the CMBR. A new class of planet; two new kinds of stars predicted years ago and now finally observed. We’re landing on asteroids. We’re landing on comets. It fortunately, just won’t stop. WooHoo! I have often told my students that I wished that I taught History. After all, the 17th century is done. Stick a fork in it; 1650 won’t happen again and what did happen won’t change. I apologize to History aficionados out there and I know I’m exaggerating, but by comparison, Astronomy marches on! So, march on we will, starting again in January and proceeding monthly (3rd Sunday, 7:00 pm) trying to keep up with new ideas, new discoveries and new meanings. We will be covering topics old as well as new across the entire spectrum of Astronomy. The A2Z Astronomy classes are free to any COC member and have no pre-requisites other than the desire know more. Pay attention to this space over the next few months for details on upcoming class details. WooHoo! September has treated us to some of the best day and night time skies of the year. Solar observing has been good with many large prominences around the edge of the sun and long black filaments arcing over the solar surface. A telescope with an H-alpha filter is required to see these features. However, if you have an internet connection, you can become a solar observer without having to purchase a telescope and filter. The National Solar Observatory (NSO) has a web page that updates once every minute with full disk images. The solar images are acquired from observatories around the world in many different time zones. It is possible to monitor the sun 24/7 from this page. The link is http://halpha.nso.edu/index.html If you explore the website, you will find that you can observe movies and time lapse videos from these observatories as well as click on the images and enlarge the area that interests you. Just a reminder: October will have a total lunar eclipse on the early morning of the 8th, and a partial solar eclipse in the late afternoon of the 23rd. Good luck to all observers! Looking for one site to find this summer’s best outdoor recreation events? http://meetmeoutdoors.com Craig’s Corner By Craig Niemi, Executive Director We hope you made it to September’s ScopeOut Astronomy Fair! If you didn’t make it you missed; a helicopter landing and taking off from the parking circle; the state-of-the-art Tesla; dozens of great vendors & exhibitors; hands on science experiments and demos - just too many activities to mention in this short space. Dean’s PBS Star Gazer co-host, James Albury gave a humorous and inspiring keynote lecture. The weather was ideal. Even the late day shower of golf balls was a welcomed event. Congratulations to Sam Vessel and Dave Kuhl, winners in our first annual helicopter golf-ball drop fundraiser. Thanks go out to Dale Zoller and all the hard-working volunteers who put on an awesome event. And a huge thank you to the UC Physics Department for their generous support of our annual celebration of STEM! Hopefully we inspired many to a career in the sciences or a lifelong quest as an amateur astronomer. 7 The Power of Eclipses By Aashi Mital As we head into October, we’re graced with a total lunar eclipse and a partial solar eclipse, but one cannot help wondering about how these astronomical events were seen by various cultures throughout the world and how they influenced history. Every schoolchild has been taught that Christopher Columbus came ashore on an island northeast of Cuba in 1492, but did you know it was an eclipse that saved Christopher Columbus? On his final voyage, bad luck struck in the form of worms. Shipworms ate holes through the planking, forcing Columbus to beach his last two leaky caravels and make repairs on St. Anne Bay off the coast of Jamaica. These men intrigued the natives and for over six months the natives provided provisions. Unfortunately, the crew ultimately mutinied, robbed and murdered several natives. In turn, the Jamaicans cut off their food supply. In order to avoid famine, Columbus came up with a plan. Even though he was not a scholarly man, the explorer had a copy of Regiomontanus' (the German mathematcian and astronomer) almanac to help him navigate the open seas. He discovered that a total lunar eclipse would take place on the evening of February 29, 1504. He told the native chief that his Christian god was angry and in three nights he would all but remove the Moon from the sky, bathing it an inflamed wreath to signify punishment upon the natives. On the evening of the eclipse, it looked as if something was wrongthe Moon was bloody red and the lower half was missing. The natives promised to cooperate if the Moon was restored. Columbus locked himself in his cabin to talk with his god and just before the end of the eclipse Columbus came out, stating that they had been pardoned. He and his crew were well looked after until relief arrived to take them back to Spain. Save the Date! Meet a Meteor!

One Planet, Two Stars: New Research Shows How Circumbinary Planets Form 9 An artist's conception of Kepler-34b which orbits a double-star system. Like the fictional Star Wars planet, Kepler-34(AB)b is a circumbinary planet, so-called because its orbit encompasses two stars. Powerful gravitational perturbations from the two stars on the rocky building blocks of planets lead to destructive collisions that grind down the material. So, how can the presence of such planets be explained? http://www.sciencedaily.com/rel eases/2014/01/140131130757.htm The Sun’s Turn To Be Eclipsed Thursday, October 23rd 5-7 pm Join us at Ault Park Stargazing at Stonelick State Park Saturdays – October 18th & 25th A Telescopic View of Andromeda Need help with your telescope?

Our Milky Way galaxy is about 100,000 light years across, and contains about 200 billion stars. The largest known galaxy (IC 1101) is about 6 million light years across, and has a mass of about 100 trillion solar masses. The smallest galaxy? It has about a thousand stars. http://phys.org/news/2014-09small-galaxies.html#jCp 10
