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.

Three planets visible in the early evening!

Venus is very low in the West after sunset.

Mars is in the low S/SW at sunset.

Saturn is in the low S/SW at sunset

Jupiter rises in the East just before sunrise.
