About the General Meeting Presentation

Brian Cudnik discusses the status of our search for our "home away from home" in another planetary system. This presentation includes a brief introduction to exoplanets, along with some visualization of what they may look like, with an emphasis on Earth-like worlds around other stars.Cudnik shares the latest score on how many planets we have found and highlights some of the most interesting multi-planet systems that the Kepler satellite has found to date.

At the Novice meeting:  The February 6th meeting occurs just as Jupiter is reaching opposition or the closest point in its orbit to us. Expert planetary imager Bill Flanagan will speak on “Observing Jupiter” and tell us everything you wanted to know about Jupiter as well as introduce you to what is involved in becoming a good planetary imager.  In the future we will look at having a more detailed talk dedicated to planetary imaging.

Shallow Sky Object of the Month: Diadem—Alpha Com

Original article appears in GuideStar January, 2015.

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

Original article appears in GuideStar January, 2015.

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.
