Approximately twenty people attended the event. Speakers included Terry Stewart, Bill Griffith, Dennis Amman, Bob Wexel, and Alice Harvey. They shared information and stories about Mike. One was about how he had attended every Riverside Telescope Makers Conference (RTMC) event since the mid-1980s. Another was about how he wouldn't hesitate to help people such as assisting Terry Stewart move from one residence to another. And a humorous story was how "he was a happy drunk" and would giggle endlessly when he'd had enough. Arguably the most significant contribution that Mike made to the SDAA was being "The Original SDAA Star Party Coordinator" for so many years, starting the Camp with the Stars events at Heise and Vallecitos, as well as coordinating the entire county before the club split it up into four current area coordinators. He did it for about 30 years, and the majority of it all by himself. Amazing! Mike had put around 300,000 miles on his old Probe driving to all those school and public star parties back in the day, eventually requiring major repairs. And the estimated quarter million to a third of a million people that looked through his telescope at all those events? Astonishing! Life is better with people like Mike in it! The friendly disposition, the perpetual smile, the humbleness. He passed away from cancer, in just five months after being diagnosed, in April, 2016. He was only 55 years old. A modification from Dion's song 'Abraham, Martin and John' -- "Has anybody here seen my old friend Mike? Can you tell me where he's gone? He was loved by a lotta people. But it seems that the good, they die young. You know, I just looked around, and he was gone." 5 San Diego Astronomy Association 6 San Diego Astronomy Association 7 San Diego Astronomy Association Sunday Monday 1 August 2016 Tuesday 2 Wednesday Thursday 3 4 5 Julian StarFest Julian StarFest 11 12 Stars in the Park 7 8 New Moon Viewing 14 9 New Moon 10 SDAA Business Meeting 15 16 22 23 17 24 AISIG Meeting 28 29 SPIE Convention Star Party 30 Saturday 6 Julian StarFest 13 Stars at Mission Trails SDAA Program Meeting 21 Friday 31 18 19 20 25 26 27 Kids-n-Cancer West Sycamore TDS Public Night 1 2 3 Stars at Sycamore Canyon Full Moon KQ Ranch TDS Member Night Cuyamaca State Park 8 San Diego Astronomy Association SDAA Contacts President Vice President Recording Secretary Treasurer Corresponding Secretary Director Alpha Director Beta Director Gamma Director Delta Club Officers and Directors Mike Chasin Greg Farrell Brian McFarland Gene Burch Nick Andrews Dave Decker Dennis Ritz Michael Vander Vorst Dave Wood President@sdaa.org VicePresident@sdaa.org Recording@sdaa.org Treasurer@sdaa.org Corresponding@sdaa.org DirectorDelta@sdaa.org DirectorBeta@sdaa.org DirectorGamma@sdaa.org DirectorAlpha@sdaa.org (858) 210-1454 (858) 705-0065 (619) 462-4483 (858) 926-9610 (858) 215-0479 (619) 972-1003 (619) 890-7480 (858) 755-5846 (858) 735-8808 Committees Site Maintenance Bill Quackenbush TDS@sdaa.org(858) 395-1007 Observatory Director Jim Traweek Observatory@sdaa.org (619) 207-7542 Private Pads Mark Smith Pads@sdaa.org(858) 484-0540 Outreach Kin Searcy Outreach@sdaa.org (858) 586-0974 N.

July2016 Venus and Jupiter prepare for their close-up this August By Ethan Siegel As Earth speeds along in its annual journey around the Sun, it consistently overtakes the slower-orbiting outer planets, while the inner worlds catch up to and pass Earth periodically. Sometime after an outer world—particularly a slow-moving gas giant—gets passed by Earth, it appears to migrate closer and closer to the Sun, eventually appearing to slip behind it from our perspective. If you've been watching Jupiter this year, it's been doing exactly that, moving consistently from east to west and closer to the Sun ever since May 9th. On the other hand, the inner worlds pass by Earth. They speed away from us, then slip behind the Sun from west to east, re-emerging in Earth's evening skies to the east of the Sun. Of all the planets visible from Earth, the two brightest are Venus and Jupiter, which experience a conjunction from our perspective only about once per year. Normally, Venus and Jupiter will appear separated by approximately 0.5º to 3º at closest approach. This is due to the fact that the Solar System's planets don't all orbit in the same perfect, two-dimensional plane. But this summer, as Venus emerges from behind the Sun and begins catching up to Earth, Jupiter falls back toward the Sun, from Earth's perspective, at the same time. On August 27th, all three planets—Earth, Venus and Jupiter—will make nearly a perfectly straight line. As a result, Venus and Jupiter, at 9:48 PM Universal time, will appear separated by only 4 arc-minutes, the closest conjunction of naked eye planets since the Venus/Saturn conjunction in 2006. Seen right next to one another, it's startling how much brighter Venus appears than Jupiter; at magnitude -3.80, Venus appears some eight times brighter than Jupiter, which is at magnitude -1.53. Look to the western skies immediately after sunset on August 27th, and the two brightest planets of all—brighter than all the stars—will make a dazzling duo in the twilight sky. As soon as the sun is below the horizon, the pair will be about two fists (at arm’s length) to the left of the sun’s disappearance and about one fist above a flat horizon. You may need binoculars to find them initially and to separate them. Through a telescope, a large, gibbous Venus will appear no more distant from Jupiter than Callisto, its farthest Galilean satellite. 11 San Diego Astronomy Association NASASpacePlaceAstronomyClubArticle July2016 As a bonus, Mercury is nearby as well. At just 5º below and left of the Venus/Jupiter pair, Mercury achieved a distant conjunction with Venus less than 24 hours prior. In 2065, Venus will actually occult Jupiter, passing in front of the planet's disk. Until then, the only comparably close conjunctions between these two worlds occur in 2039 and 2056, meaning this one is worth some special effort—including traveling to get clear skies and a good horizon—to see! Image credit: E. Siegel, created with Stellarium, of a small section of the western skies as they will appear this August 27th just after sunset from the United States, with Venus and Jupiter separated by less than 6 arc-minutes as shown. Inset shows Venus and Jupiter as they'll appear through a very good amateur telescope, in the same field of view.
