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.

Proposed changes to the HAS Bylaws for your review

Changes to the bylaws of the Houston Astronomical Society were presented to the board by three members of the executive committee - Bill Pellerin (president), Rene Gedaly (vice-president), and Bill Flanagan (secretary). Scott Mitchell has also helped with the review.

The purpose of the modifications is to make the document easier to read and understand and to resolve some issues that get in the way of the organization being able to conduct its business.

The board voted unanimously to support the adoption of the modified bylaws at its 9/17/2014 board meeting. Bylaws changes must be approved by the membership and will be presented at an upcoming meeting.

The summary of changes, proposed bylaws, and existing bylaws documents are linked below.

    • Our vice-president, Rene Gedaly, leading our nominating committee announced that they now have candidates for all available positions. Elections are at the annual membership meeting.
    • A budget request for web-hosting of our meeting videos was approved, and a budget request for a one-time purchase of a backup hard drive was approved.
    • A proposal to establish a commercial relationship with our website hosting service was accepted.
    • A request from the observatory committee to fund the establishment of additional parking and camper spaces, and to improve existing camper spaces, was approved.
    • The board voted unanimously to recommend to the membership that the annual meeting (normally in November) be moved to December (2014).

    Have You Seen the All-Sky Camera?

    The HAS observatory site now has an all-sky camera in place. It works great. I was watching it last night and I could see several bright stars and the Milky Way in the image it returned. Many thanks to Mike Edstrom who got this going, and to an anonymous donor who paid for the purchase of the camera.

    I’m very pleased to hear that Mike is offering his services as Observatory Director for 2015. There have been some significant improvements at the site recently, including the weather reporting system, and the private observatories. As Mike says in his Observatory Corner article, all the private observatory sites are under subscription, so the demand has exceeded the supply. Stay tuned, there may be other opportunities for private observatories.

    The HAS Elections for 2015

    Right on schedule, the nominating committee headed up by Rene Gedaly, our VP, is up and running. A number of the leaders of the HAS have agreed to run again for the office they currently hold. Some of the positions will become vacant, so the committee will be searching for new nominees to fill those positions.

    Many thanks to those who have served the organization in 2014 as officers, board members, elected committee leaders, or as leaders of ad-hoc committees. More about this as we approach the end of the year.

    Look for Rene’s article about the nominating process on page 8 in this issue of the GuideStar. I hope you’ll offer to help the HAS in 2015. There’s always more opportunity to serve the membership than there are people willing to take on the tasks. The board often hears of good ideas for new HAS initiatives, but without the volunteers to make those ideas a reality they never get off the ground.

    The production of the GuideStar is something I’ve done for quite some years, and I’ve enjoyed every minute of work I’ve put into it. It’s time for someone to step up and take this on for the future. There are plenty of sources for good content in the newsletter. I love to get content comes from our HAS members, but I get content from the AAVSO, from the NASA Space Place, and now from the UT/McDonald Observatory. The job entails formatting that content for the newsletter, dropping in into the publication and adding some content where necessary.

    Anyone interested in this role in 2014 can contact me by email—guidestar@astronomyhouston.org.

    Shallow Sky Object of the Month: HD 162826

    Original article appears in GuideStar September, 2014.

    HD 162826

    by Bill Pellerin, HAS president & editor of the GuideStar

    Object: HD 162826 Class: Star
    Constellation: Hercules
    Magnitude: 6.5
    R.A.: 17 h 51 m 14 s
    Dec: 40 deg 04 min 21 sec
    Size/Spectral: 1.15 solar mass, F8V
    Distance: 110 ly
    Optics needed: Binoculars or small telescope

    Why this object is interesting:

    We all know that stars are ‘born’ in clusters. The evidence of that is easy to find. The Pleiades is a cluster of relatively young stars which have yet to completely shed their cocoon of dust and gas. The Orion Nebula is an example of stars in an earlier stage of development, still enshrouded with the dust and gas that is forming the stars.

    It should be no surprise, after all, that our sun was born with other stars and that a bit of looking around and analysis of nearby stars would allow us to identify the Sun’s siblings. Astronomers at the University of Texas McDonald Observatory, led by Ivan Ramirez, have done just that, and this summer announced that HD162826 is one of those sibling stars.

    How do they know? For one, the star has a similar chemical composition to our sun, and while it is comprised mostly of hydrogen and helium, it also has some elements in common with the Sun… barium and yttrium. Relatively young stars like our Sun have formed in a universe in which earlier stars have cast off some of these heavy elements. The concentration of these heavy elements in the interstellar medium is not uniform, however, so clouds of similar elements form stars with similar elements. The cluster in which this star and our sun formed is likely to be an open cluster. Globular clusters are older and tend to keep their shape as a globular because of the mutual gravity among the stars. Click read more
