Celestial Observations: Stargate Asterism

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.

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

Mars

Thanks to one of our Observing Program Coordinators, Vince Foster, this is a link to a great article on the Apparition of Mars (going on now…).

Enjoy.  Aaron

Observing Program Director – going off-line

From now until the end of August, if you have any needs related to the Astronomical League’s Observing Programs and Awards, please work directly with the Coordinators.  If you have needs that they can’t solve, then please address all emails to the other Observing Program Director, Cliff Mygatt at cliffandchris@wavecable.com.  Thanks.  have a great summer, and do lots of observing.  Aaron Clevenson

The Correct LEDs for Chicago

Light pollution and the encroachment of sky glow are subtle yet pervasive problems that adversely affect our lives in many ways. The Astronomical League stands firm in its position advocating the responsible use of outdoor lighting: The right amount of light, in the right direction, at the right time.

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:

The Astronomical League supports rational and civil discourse to illuminate the facts about LED lighting and light pollution.

Olympic Astronomical Society donates Horkheimer/Library Telescope

The Olympic Astronomical Society (OAS) in Bremerton just handed over their first Library Telescope to the Kitsap County Library, Sylvan Way branch, Wednesday 30 March. Cliff Mygatt, President of the OAS, presented the telescope to Librarian Megan. The telescope was won from a drawing held at the Astronomical League Convention in July and sent to the OAS in October, the telescope and accessories were donated by Orion Telescopes and Celestron International to the Astronomical League for the drawing. The program was made possible by the vision of the Horkheimer Charitable Fund.

The OAS was one of ten astronomy clubs nationwide to win the Library telescope. Cliff Mygatt modified the Orion telescope per the instructions from the New Hampshire Astronomical Society. The OAS in league with the Battle Point Astronomical Society are working to get more telescopes in the hands of Kitsap County Library members and encourage them to look up at the universe and wonder!

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.

A Total Eclipse of the sun is coming!

ASTROCON 2017 (ALCon 2017) registrations are coming in daily. League club members who want to attend should register soon, so as to not miss this opportunity. Hotel and motel accommodations are booking quickly for this event!

Please go to the event website at http://astrocon2017.astroleague.org, then go to the “Registration” tab to complete your online registration.

The MARS region of the Astronomical League is helping to plan ASTROCON 2017 in the days leading up to the total solar eclipse of August 21, 2017.  Volunteers from various clubs in the Utah, Montana, Wyoming and Colorado are actively involved helping to plan and coordinate this event. This will be a major outreach opportunity for amateur astronomy……a total solar eclipse!

ASTROCON 2017 is collaborating with and supporting the Wyoming Eclipse Fest to help educate and support the many eclipse chasers that will descend upon Casper for AMERICA’s GREAT ECLIPSE!  Casper lies directly on the centerline of the moon’s shadow and has excellent weather prospects for a clear, dry eclipse day.
