Welcome to Houston Astronomical Society

Founded in 1955, Houston Astronomical Society is an active community of enthusiastic amateur and professional astronomers with over 60 years of history in the Houston area. The club meets on the first Friday of each month at the University of Houston. Membership has a variety of benefits, including access to a secure dark site west of Houston, a telescope loaner program, and much more. Joining our club is simple; you can sign up online, by mail or in person at a monthly meeting.

Shallow Sky Object of the Month: Diadem—Alpha Com

The Diadem

by Bill Pellerin, GuideStar editor

Update: The AAVSO has posted a notice on its web site that the eclipse will not happen at the anticipated date and time.

Object: Diadem—Alpha Com
Class: Double Star
Magnitude: 4.32
R.A.: 13 h, 9 m, 59 s
Dec: 17 degrees, 31 minutes, 48 seconds
Distance: 47 ly
Constellation: Coma Berenices
Spectral: F2
Optics needed: Unaided Eye

Why this object is interesting

The name of this star means crown or other ornament representing royalty. In this case the crown is in the constellation Coma Berenices (Berenice’s hair) and this star represents the crown on the head of queen Berenice.

All well and good, but the thing that makes this star interesting to observers is that it is a binary star consisting of two mag 5 stars very near each other and with an orbital period of about 26 years. Remember that orbiting objects orbit around the center of mass of the system, so, in this case it’s more like a dance in the sky than it’s like a low mass object orbiting a high mass object.

President's Message

by Rene Gedaly, HAS president

Thank you for voting in the 2015 leadership team; they’re a dynamic group and you can expect continued great things from them. I’m honored to be the next HAS president, and before talking about plans for 2015, I'd like to reflect on how much has been accomplished during the tenures of my recent predecessors.
The framework for a 21st century society
The new website had its genesis while Ken Miller was president and it continues to transform our organization. Gordon Houston developed a new set of observers through his basic observational astronomy class, a well-attended urban observing program, and his two-minute drill that brought basic astronomy education to the general membership meeting. The scaffolding was now in place for an HAS renaissance.
