Celestial Observations: Stargate Asterism (2016)
By Bill Pellerin, Houston Astronomical Society
The first time I ever heard of the Stargate asterism was when I picked up a copy of John Wagoner’s observing list at the Texas Star Party some years ago. The asterism was mentioned by the well-known observer Philip Harrington in a May, 1998 article in Sky and Telescope magazine, but John tells me that he’s the guy who created the identifier ‘Stargate’ for this collection of stars.
2016 Transit of Mercury
Reminder: Tomorrow morning (in the US) is the Transit of Mercury across the face of the Sun. This is a somewhat rare event and if your skies are clear be sure to check it out. Don’t ever look at the sun without proper protective filtering. Mercury will be too small to see with welder’s glass or eclipse glasses.
Also, remember that we have a Special Observing Award for the transit:

Good luck. Aaron

The Correct LEDs for Chicago (2016)
The city of Chicago is planning to install 270,000 LEDs. It would benefit the quality of life of the residents in that area if those LEDs had a correlated color temperature of 3000K or less, and if their associated fixtures were fully shielded and pointed downward. In light of that, a petition to the mayor of Chicago, Rahm Emanuel, has been created to show support of quality outdoor lighting.
Petition. Bring Back Chicago’s Starry Night with Responsible City Lighting:
Contact Audrey Fischer of the Chicago Astronomical Society for more information.
The Astronomical League supports rational and civil discourse to illuminate the facts about LED lighting and light pollution.

Celestial Observations Denebola— β Leo (2016)
By Bill Pellerin, Houston Astronomical Society
Object: Denebola — β Leo
Class: Star
Constallation: Leo
Magnitude: 2.14
R.A.: 11 h, 49 m, 04 s
Dec: 14° 34’ 19”
Size/Spectral: 1.75 Solar Masses, Color: A3
Distance: 35.9 ly

The name of this star may seem somewhat familiar. There’s another star in the sky named Deneb, in the constellation Cygnus (the swan). The name Deneb is from the Arabic word dhaneb which means ‘the tail’. The name Denebola is a combination of the Arabic words Deneb Alased, meaning the tail of the Lion, which, in fact it is. It lies at the eastern end of the constellation Leo the Lion.
