Honoring an SDAA Member and a Friend
By Craig Ewing
On Friday, June 8th at Mission Trails Recreational Park, members of the San Diego Astronomy Association gathered to pay respect
to long-time member Mike Dietz. 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."

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.

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.
To teach kids more about Venus and Jupiter, visit the NASA Space Place webpages titled
“All About Venus” [http://spaceplace.nasa.gov/all-about-venus/en/] and “All About
Jupiter” [http://spaceplace.nasa.gov/all-about-jupiter/en/].
