About the General Meeting Presentation

Richard has carried out brightness measurements of the brighter planets in visible light since 1991. On April 25, 2014, he made his first brightness measurement using the J and H filters. The J and H filters are sensitive to light with wavelengths of 1.25 and 1.65 micrometers, respectively. Visible light has wavelengths of between 0.4 and 0.7 micrometers. The brightness of Venus is consistent with the light being reflected off of the cooler layers of its atmosphere. This is not the case for Mercury. It is very bright in the H filter. The albedo of Mars levels off in the J and H filter which is different from what it does in visible light. Jupiter is dimmer in the J and H filters than in visible light. Saturn’s rings have a big impact on that planet’s brightness. These results and others will be presented in this talk.

HAS Organization Status

Thanks to some legal work, done by HAS member Scott Mitchell, the status of the Houston Astronomical Society as a non-profit educational organization has been confirmed by the State of Texas. This work was in addition to the work done with the Colorado County taxing authority to assure that the organization was not liable for property tax for our observing site. The board of directors greatly appreciates Scott’s contribution of time and expertise on this issue.

The Houston Astronomical Society Election

It’s only July, but it’s probably not too early to be thinking about the 2015 year of the HAS. The nominating committee is obliged by the by-laws to present candidates for the various elected offices of the HAS at the October meeting. This means that it won’t be long before the nominating committee will start calling HAS members to assess their interest in holding one of these elected offices.

You can get a jump on the nominating committee by contacting our VP (Rene Gedaly) and expressing your interest in one of the elected offices. There are 4 officers, 5 board members, and 9 committee leaders to be nominated. Read the by-laws to get the list of elected positions. There’s a link to the by-laws at the bottom of the home page of the HAS web site.
