Our February “This Sky this Month” show will be offered this Sunday, Feb. 12, at 4:00 PM and Monday, Feb. 13 at 12:00 Noon. Topics will include the stars and constellations of late winter, the approach of Jupiter and Venus in the evening sky, as well as current astronomy news. Shows are free and open to the public as always. Directions, etc., are available on the web site.

Monday lab had a good session last night, though a little cold. After a visual tour of the sky (dominated by the almost-full moon), we used a Meade telescope to observe Venus, Jupiter, the Orion Nebula, the Andromeda Galaxy and the moon. A look at the dome room and control room of the observatory building wrapped up the evening. The image on the right, taken at 6:38 PM, shows Jupiter (above), Venus (below), and the observing deck illuminated by moonlight. Look for Venus and Jupiter to draw closer together over the next few weeks, eventually passing about three degrees from each other on March 12.
A couple notes about the schedule. Classes at the College did not start until Jan 23, so we will be doing the new year show the last Sunday and Monday of January. That works out well with our February sky show, which will be a week later than usual to avoid the superbowl. Other than that, it’s first Sunday at 4 PM and first Monday at noon until May.
If you are interested in a private show for a school or community group, please contact us soon since our spring calendar tends to fill up and we typically do not schedule private shows after April due to the student workers’ busy academic schedules.

Here are some photos taken on and around the observing deck at our session Monday night. The first two show the International Space Station, which passed over just before our first session. First shot is of the ISS appearing and moving up in the southwest, the next is shows it at max altitude and brightness (mag -3.3). Both are 15 sec exposures. The last shows Jupiter rising over the GC Observatory. It’s a 30 sec exposure on an ordinary tripod with no tracking, so if you zoom in you can see that Jupiter and the stars moved during 30 seconds of the earth’s rotation! Note the Pleiades just to the right of the observatory dome.

Our monthly skyshow series returns for the 2011-12 academic year this Sunday, Sept. 11, at 4 PM and Monday at noon. Full calendar is available on the planetarium web site. Topics will be the September skies as well as astronomy news, including the unusual supernova pictured here.
At left is a photo I took of the waning crescent moon and Venus at 6:16 AM on March 1. Upcoming moon-planet meetings include one with Jupiter tonight, visible if the clouds clear in time. In that case, it would be a waxing crescent moon in the west after sunset. Another moon-Venus morning conjunction will occur on March 31, a little lower in the east than the one pictured here.
Hear about these events and more at the Sky this Month shows today at 4:00 and tomorrow at noon.
Our goal is to do the “Sky this Month” shows on the first Sunday and Monday of the month, except where outside factors interfere. Since its move to February, we have learned not to fight the NFL Superbowl. That’s why there will be no show this Sunday, Feb. 6. Instead, the February sky-shows are Monday Feb. 7 at 12 noon and Sunday, February 13 at 4:00 PM. These shows, and the rest of the Spring 2011 schedule, can be found on the planetarium web site.
