Mercury Transit Across the Sun (November 11, 2019)
by Jim Knoll
Monday November 11, 2019 (Veterans Day). This is a school holiday and a work holiday for many. Don’t pass up this “seldom-in-a-lifetime event”. A Mercury Transit (passing in front of) will NOT be visible again in the U.S. until May 7, 2049. Transits occur only 13-14 times per century. A Mercury Transit is too small to see without a properly filtered solar telescope. When you observe a transit, you see a small black circle (the planet Mercury) moving across the Sun. This event is visible throughout the U.S. TAAA will have several solar telescopes to safely view the Transit at Brandi Fenton Memorial Park (3482 E River Rd, River & Alvernon) on November 11 from 7:30 – 11 am (Mercury mid-transit when it is crossing the middle of the Sun is at 8:20 am Tucson time). Sunrise November 11 is 6:49 am and the Transit will already be underway. You can follow the Mercury Transit event on our Facebook page (facebook.com/tucsonastronomy) for real-time weather updates. This event requires a clear view of the Sun (no cloud cover). CAUTION: Never look at the Sun without a proper solar filter or you can damage your eyes.

Title: Remote Observatory Operation, the good, the bad, and the ugly: or what can go wrong with your observatory?
Speaker: Tim Hunter has been an amateur astronomer since 1950, and he is the owner of two observatories, the 3towers Observatory and the Grasslands Observatory (http://www.3towers.com). He also considers himself “a prime example of someone whose hobby has run amok, spending more time and money on it than common sense would dictate.” Tim has been the President of the Tucson Amateur Astronomy Association, Inc. (TAAA) and a member of the TAAA since 1975. He is the immediate past Chair of the Board of Trustees of the Planetary Science Institute (PSI). For decades, he has been interested in the growing problem of light pollution. In 1987, he and Dr. David Crawford founded the International Dark-Sky Association, Inc. (IDA). IDA is a nonprofit corporation devoted to promoting quality outdoor lighting and combatting the effects of light pollution.
Tim’s talk to TAAA will describe his experience owning and operating the Grasslands Observatory near Sonoita, Arizona. As Tim explains: “The observatory was founded in 1987 and evolved from a mainly visual use facility to three remotely operated telescopes used for astrophotography.” He will illustrate the evolution of the observatory, and discuss remote telescopic operations in general and how his three telescopes—a PlaneWave CDK24 24-inch f/6.5 telescope, an ASA 20-inch f/3.6 telescope, and a Takahashi Epsilon 180 f/2.8 telescope—are remotely operated from Tucson and used for various astrophotographic projects. As Tim explains, “Remote telescope operation is quite possible and offers great convenience with respect to travel and sleeping. It comes with considerable costs including monetary as well as the need for constant attention to maintain the operation. Things can and will go wrong. One must be prepared to respond to the gravest of contingencies at a remote location in the darkest hours of the night. “

Title: A Nightwatchman’s Journey: The Road Not Taken
Speaker: David H. Levy. A renowned amateur astronomer, David has never taken a class in astronomy, yet has authored over three dozen books, written for three astronomy magazines, and appeared on TV programs featured on the Discovery and the Science Channels. Among David’s accomplishments are 23 comet discoveries, the most famous being Shoemaker-Levy 9 that collided with Jupiter in 1994, a few hundred shared asteroid discoveries, an Emmy for the documentary Three Minutes to Impact, five honorary doctorates in Science and a PhD which combines astronomy and English Literature. Currently, he is the editor of the web magazine Sky’s Up!, and has a monthly column, Skyward, in The Vail Voice newspaper.
With slides and music, David’s presentation will focus on his most recent book, A Nightwatchman’s Journey: The Road Not Taken; the autobiography of one of today’s most enthusiastic and famous amateur astronomers. David will share how his passion for astronomy began in his native Canada, and his 19-year search for comets until he found his first in 1984. (He has gone on to find 22 more.) David will also share his love for astronomy in literature, his personal struggles, and why he subtitles his autobiography, “The Road Not Taken.” Expect a fascinating lecture from a nightwatchman who continues to hunt for comets and asteroids, and lecture worldwide. Refreshments and a book signing ($35 a copy) will follow.
* Voting will be held at 7:30 meeting on two proposed TAAA bylaws changes. *
