We’ll hold our August meeting on Friday, August 7, at 7:45PM, in room 215 of Davis Hall, the Aerospace Engineering Building. The doors to the building automatically lock at 8:00PM, so if you’re running late, rap on the door nearest our meeting room and we’ll let you in.
Our new moon star party this month will be on Saturday, August 22 at Cliff Hill’s farm, clouds permitting of course.

On July 18, Frank Ward, Alan Cook, Russell Whigham, and Larry Jenkins, and his girlfriend Kelly met at Cliff Hill’s farm for an evening of unseasonably cool air. We had a couple of virtually cloud-free hours, but were pestered with spotty high clouds most of the evening. Through a thin cloud parked right over the 10th magnitude star, I was able to observe it as it dimmed to the brightness of the asteroid (790, Pretoria) at the appointed time, but with only 50% certainity that it was the actual occultation and not just extinction by the moving clouds. No solid data to report. However, several people in Georgia, using photometric observations, determined the the target star was a previously unknown binary! See their results at: http://www.asteroidoccultation.com/observations/Results/.
Scroll down to the 2009/07/19 results for 790, Pretoria, and click on the “Asteroid Profile” links to see the photometric light curves. I encourage everyone to try this the next time the opportunity presents itself.
CalSky I recently discovered a service from http://www.calsky.com/. Not only will it alert you of ISS and STS passages ( I actually like Heavens-Above maps better for this), but also when the satellites will transit the Sun or Moon. My favorite feature is the prediction of Iridium Flares. Unlike the ISS passages, these are very local predictions. I just dragged the house icon on the map to my exact location (it somehow knew I lived in Montgomery), entered a user name and password, then my e-mail address. You can select from a menu if you'd like ISS passes, ISS transits of the sun and moon, Iridium flares, and many others, or all of them. I also changed my alert notice interval to one day prior to the event. A few minutes later, I received an e-mail, alerting me to a -7.2 iridium flare. Here is an example of the lunar transit alert. (This will only be good for people on the east side of Montgomery).

AAS Shirts We want to remind you that the current shirt offer will expired July 27th. From now on, shirts will be available by contacting us and dealt with on a one to one basis. Steve Durham at Marge's Monograms.
Light in your eyes? I saw this and
had to share. Just seems like something we would do!

Possible Perseid Meteor Outburst: This
year's Perseid meteor shower could be even better than usual. According
to NASA's Meteoroid Environment Office, a filament of comet dust has drifted
across Earth's path and when Earth passes through it, sometime between
0800 and 0900 UT (1 - 2 am PDT) on August 12th, the Perseid meteor rate
could surge to twice its normal value. Check http://spaceweather.com
for details and observing tips.
