Public Viewing Nights

Open House Nights for 2016

The public viewing season for 2016 is now over because the chill of winter is nearly here. The season was especially successful because of the clear weather on 6 of the 7 events. We estimate that over 750 guests came.

Check back in early 2017 for next years schedule of open house nights at our observatory. However, we still have our general meetings and the public is always invited.

Venus is the very bright "star" in the Southwest after sunset.

Mars is in the low S/SW after sunset.

Jupiter rises in the East a few hours before sunrise.
