Nominations will be accepted through April 23 for all open positions: • President • Vice President • Secretary • Treasurer • Chairperson of the Finance Committee • 2 Directors-at-Large Please email nominations to jvsperoni@yahoo.com. Include your name, mailing address, phone number, the name of the member being nominated (which can be yourself), and the position. (The Election Committee will confirm receipt of your nomination; if you do not re- ceive that confirmation within 3 days please contact us again). Email is greatly preferred, but you may also use paper mail addressed to PO Box 1204, Attn: Custer Election Committee, Southold, New York 11971. A list of all nominees will be published online after nominations close, followed by a paper mailing of election information. Note that the membership voted to change election procedures at the 2013 Annual Meeting. Nominations from the floor are no longer permitted. If you plan to nominate yourself or another member, you must notify the Election Committee by 4/23/14. Any questions about this email or the election process can be sent directly to me at jvsperoni@yahoo.com or 631-547-0912. Sincerely, -The Custer Election Committee (John Speroni, Rich Huber, Annette DeGiovine-Oliveira) President's Comments If you’re like most people around here, you must have joyfully greeted the change in weather that has finally come to us here on Long Island. It has been notably one of the longest winters that we’ve had in quite some time. I hope that it’s not going to be the new norm here because it was so bad that my observing time was severely restricted for the last 6 months. Our Spring hopefully will run for a while more so that we can enjoy the weather for a time at least. Now that it is Spring, it’s time to think about nominations for the election to be held at the Annual Meeting on June 7th at the end of the season. Nominations were accepted through April 23 for all open positions. You can contact any one of the three election committee persons, John Speroni, Annette DeGiovine-Oliveira or Rich Huber, with any questions. John has been holding his cards close to the vest even with me, but he did reveal that we have at least one person running for each of the open positions and one contested position so far. It is noteworthy that there has been one change in the constitution to allow for the process to be more transparent and that is the part that basically says that all nominations have to be done before the annual meeting so that members will have time to know who the candidates are well in advance of the vote. There will be one notable change and that is the position of secretary, Justine Haupt has graciously taken over the helm of Custer Jamboree Chairperson and is dedicating herself to putting on another great event in the Fall. Thanks Justine and if there is anyone else out there who would like to get in on the action and hasn’t said so already, please contact her. Let’s not forget to give George Lamonga a big thank you for getting the ball rolling for the last two years either. It’s not easy and at times probably quite a stressful responsibility. Despite the weather there have been a few new things by Bill Bogardus happening. Our invitation to the Amateur Radio enthusiasts to come share their passion with us at Custer has been accepted. In much the same manner as we share space and fellowship with AOS and ASLI, the members of PARC (Peconic Amateur Radio Club) will be present from time to time using the radio equipment and the tower to put antennas. We’ve been working out a few minor details as things have been going well so far. We need to remind ourselves that we do more than just astronomy and in fact, the amateur radio has been a big part of Custer in the past. PARC recently made a $200 donation to Custer and we are truly appreciative to them for their generosity. Another big thank you goes to Dave Barnett for taking the lead in getting our new telescope storage shed for all those extra telescopes that we are blessed to have around for outreach. We now have a place to keep yet another Obsession “Big Dob” telescope at our facility. In addition to the 25” in the Dome loaned to us by Suffolk Community College, we have a mutual agreement that allows us to use Tom Pennino’s 20” on the grounds too. This is great to have another big scope to help with the crowds. Another project that is in the works, is to finally have live video using the Mallincam on the Rowan scope which is now mounted in the North Bay, With a little help from others, Dave Barnett has done it again and gotten it all together and running. Finally, slowly but surely, Ricco has been getting his twin refractors back together after the long hiatus. Here’s hoping that it won’t be much longer. With all of this, it’s fair to say that things are looking up at Custer. Join Custer Today or give a membership as a gift! Several ways to join!

Calendar of Celestial Events May 5, 6 - Eta Aquarids Meteor Shower. The Eta Aquarids is an above average shower. In the Northern Hemisphere, the rate can reach about 30 meteors per hour. It is produced by dust particles left behind by comet Halley, which has known and observed since ancient times. The shower runs annually from April 19 to May 28. It peaks this year on the night of May 5 and the morning of the May 6. The first quarter moon will set just after midnight leaving fairly dark skies for what should be a good show. Best viewing will be from a dark location after midnight. Meteors will radiate from the constellation Aquarius, but can appear anywhere in the sky. May 14 - Full Moon. May 24 - Possible Meteor Storm. In the early morning hours of Saturday, May 24, the Earth will pass through the debris field left behind by a small comet known as P/209 LINEAR. Astronomers are predicting that this interaction may result in a brief but intense burst of meteor activity that could range from dozens to hundreds of meteors per hour. Nothing is certain, but many mathematical models are predicting that this could be the most intense meteor shower in more than a decade. May 28 - New Moon. (Nice and dark for observing!) May 10 - Saturn at Opposition. The ringed planet The Moon will be directly between the Earth and the will be at its closest approach to Earth and its face will Sun and will not be visible from Earth. This is the best be fully illuminated by the Sun. This is the best time to time of the month to observe faint objects such as view and photograph Saturn and its moons.

Springtime Visitors by John Speroni Astronomers aren’t the only evening vistors at Custer! A sneak peek at the Jamboree and a message from the Jamboree Chairperson... I’m excited to be leading the Jamboree organization this year and I expect it to be a noteworthy event. I’m especially pleased to announce that this year (and possibly subsequently), we will place an emphasis on radio astronomy. While the momentum that led to this change could be described as happenstance, I believe this might have the effect of carving out a niche for the Custer Jamboree in a region that already has access to events like NEAF and Stellafane. This may be particularly timely considering Custer’s new affiliation and friendship with the Peconic Area Radio Club, which while not astronomyrelated per se, represents a parallel and engaging avenue for STEM interest and outreach. festivities would return to Custer before the last talk of the day, which will take place immediately following a banquet catered in Stokes Hall at Custer, and not at a restaurant as has been past tradition. The main Saturday events will once again take place at the Eastern Campus of Suffolk Community College, and talks throughout the weekend will entail a mixture of both radio and visible light astronomy. What’s more, after a recent productive Jamboree planning meeting, it was decided that the Saturday I hope to see everyone there October 17-19th, and if you have an interest in helping make it a success please contact me or attend our next meeting (keep an eye out on the “listserv”: http://www.custerobservatory.org/yahoo.htm). The weekend will naturally kick off on Friday evening, at Custer, with a group poetry reading by Bob and Steve Chapin (bring your favorite astronomy poems, or write one of your own), and will conclude on Sunday with a relaxed day of talks and solar observing at Custer, including a bagel breakfast. Personally, Sunday was my favorite day last year and I hope we can recapture that air for this year. Justine Haupt Altough some things are being developed and added, this is where things are now.

The supernova in 1987, SN1987A, in the nearby dwarf galaxy, the Large Magellenic cloud, was an important step in the understanding of the physics inside of stars. It was the first, close supernova since the invention of the telescope. There were theories that many neutrinos would be released during the core-collapse, and should have reached earth prior to the photons (visible light). This was confirmed by looking back at the data collected, on dates before the light of the supernova was discovered, from three underground neutrino detectors, Kamiokande II under the Japanese Alps, IMB in a salt mine in Ohio in the United States, and Baksan under the Caucasus. The supernova was discovered by Ian Shelton and Oscar Duhalde at the Las Campanas Observatory in Chile on February 24, 1987. It brightened to magnitude 3 and was visible to the naked eye for those in the Southern Hemisphere. Of the 1058 neutrinos produced inside the star, and 1015 per square meter that passed through the earth, only 12 neutrinos were detected by Kamiokande II, 8 by IMB ad 5 by Baksan, for a grand total of 25 neutrinos. That’s it. 25 neutrinos. And all over a span of several seconds. But that was all that was needed to prove the by Steven Bellavia theory. It could have easily been missed. This recent supernova, SN2014J (“J”, for the 10th supernova discovered in 2014) was discovered by accident on January 21st, 2014, by astronomer Steve Fossey, of University College London while training four undergraduate students, Ben Cooke, Guy Pollack, Matthew Wilde and Thomas Wright, on the use of a 14-inch telescope and CCD camera at University of London Observatory. This new supernova may also provide valuable data, through spectroscopic and visual analysis. I don’t know if neutrinos have been detected. Though the galaxy M82 is close, at “only” 12 million light years away, it is still much further than the Large Magellenic cloud, which is only 168,000 light years distant. At 70 times the distance, we would be 5,000 times less likely to capture the neutrinos. And for SN1987A, only 25 neutrinos were recorded. I am sure much data will be pouring in over the next several weeks. I was fortunate that I had just imaged galaxy M82 just three weeks prior to the supernova in M82, so I have a “before” and “during” photo. The recent photo was taken on January 23rd, when the supernova was about magnitude 11.5. It is predicted to brighten to as much as 8.0 by January 29th. Types of Supernovae Supernovae are divided into two basic physical types: Type Ia. These result from some binary star systems in which a carbon-oxygen white dwarf is accreting matter from a companion. (What kind of companion star is best suited to produce Type Ia super novae is hotly debated.) In a popular scenario, so much mass piles up on the white dwarf that its core reaches a critical density of 2 x 109 g/ cm3. This is enough to result in an uncontrolled fusion of carbon and oxygen, thus detonating the star. Type II. These supernovae occur at the end of a massive star's lifetime, when its nuclear fuel is exhausted and it is no longer supported by the release of nuclear energy. If the star's iron core is massive enough, it will collapse and become a supernova.

A Mallincam video camera was installed on the north bay pier. The Mallincam takes the place of an eyepiece and allows multiple people to simultaneously view the same target on a television. by John Speroni sky. Visitors with limited mobility who have difficulty climbing two flights of stairs to the main dome, or cannot safely enter the small doorways of the ASLI and AOS domes, may be able to access the ground-level Observatory Shed. The original Mallincam installation was done using a Schmidt-Cassegrain Telecope (SCT) and f3.3 focal reducer. This setup functioned but Custer volunteers concurred that the 8” fast Newtonian astrograph built by Steve Bellavia would be a better pairing with the Mallincam. The astrograph was relocated to the north bay on April 19 and successfully used for views of Jupiter, Mars, and double stars in spite of hazy observing conditions. Continuing improvements include painting the walls black and adding curtains at the door to keep light from the television from interfering with observing on the south lawn. We are also considering adding a second telecope to the mount, so visitors can view the same object on the television and through an eyepiece to directly compare video astronomy to visual astronomy. This new video astronomy installation benefits Custer guests in many ways. Visitors now have one more instrument to look through on busy nights, decreasing queues at other telescopes. Video astronomy can display deep sky objects that are to dim to see in an eyepiece. Custer lecturers can point out details on the screen while talking about the night Many Custer members assisted with this project. Thank you to all who helped with planning, cleaned clutter from the north bay, and installed equipment. This progress is especially welcome after the cold, icy winter. The remainder of the shed is also being improved. Rico Verticchio’s homemade big binoculars (“big” is an understatement; see photo) in the center bay were recently refurbished due to damage from Long Island humidity. We also plan to improve the flow of foot traffic and refurbish the south bay 14” Schmidt-Cassgrain telescope. The Man, the Myth, the Legend....Rico Verticchio Keith Rowan (9/8/1960 – 4/8/2010) Astronomer - Teacher - Friend. I met Keith in Holy Ghost elementary school, on 46th street and 17th avenue in Brooklyn. I don’t remember what grade we became friends. I think it was around 6th grade. We both had an interest in science and astronomy. There was another friend, Gary Laverty, who also had this same interest. The three of us quickly bonded and spent much time together. People called us “The Three Musketeers”. by Steven Bellavia For all of us, astronomy was our passion. I kept it as a hobby, but Keith followed that passion much further, and earned his bachelors and masters in astronomy, going to school at night while working as a park ranger by day. Keith ultimately became an astronomy professor and ran the observatory at the College of Staten Island. We made our own telescopes, purchasing Pyrex mirror blanks from Edmund Scientific Company, along with grinding powders and books, etc. We made our own equatorial mounts out of plumbing pipes. Even under the light-polluted skies of Brooklyn, we would observe the planets, the moon, the sun, and sometimes even the Orion nebula. We entered science fairs together, taking many firsts, always as a team. I know all the students and faculty had tremendous respect and admiration for Keith. His thoroughness and enthusiasm, in everything he did, was inspiring. His license plate and E-mail were both “SKYGAZER908”, 9/08 being his birthday, which oddly enough was the last time I spoke to Keith in 2009. We would take train rides into Manhattan to go to the Hayden Planetarium. We tried to watch every science show there was on television, usually annoying our parents and siblings, who would rather watch something else, and we would have to negotiate which house we would watch them at, often taking turns. As we grew older, we went our separate ways. Gary went to California, I moved to Long Island to work for Grumman Aerospace, and Keith became a New York Park Ranger. I heard that many of the manuals and books he produced, cataloging and describing various aspects of fauna, flora and geology of the state parks, are still used as training material for new hires as well as reference sources for seasoned veterans. Gary left us very early in life, and that was sad for Keith and me. And in 2010, Keith left us too. He was only 49. He had planned a trip to China for the July, 2009 eclipse, but a heart problem kept him from going. He had successful bypass surgery, but died, unexpectedly less than a year later, in his sleep. I built the 8-inch astrograph in dedication to Keith, my first and oldest friend on this earth. A look back at last year’s Successful & Fun Custer Jamboree!
