Observatory Night for Friday 7-Jul-2017 Cancelled due to clouds

For folks who have registered for tonight, the event is cancelled. The skies have clouded up and it's extremely unlikely conditions will be acceptable for observing. Sincere apologies for the late call on this. I've been watching the satellite and sky hoping the clouds would stay north, but they have moved in on us.

Below is the latest satellite from and conditions at the observatory around 7:30pm.

As always, thank you so much for your interest in astronomy and our observatory!

"Love is in the Stars" - MC article on about our observatory

Montgomery College just put out a nice article about our observatory nights. You can find it here.

Observing log for 30 June 2017

The towering cumulus clouds stayed southwest of Rockville and the sky cleared! Seeing wasn't great, but we did manage to observe the following objects:

Overall, not a bad night. Thank you everyone for your patience with the weather and the fantastic questions. It's an honor to get to share the observatory and night sky with you.

UPDATE Observatory Night Friday 30 June - sky is clouding up

Apologies for the late notice but the sky is becoming significantly cloudier and now there is a chance of a thunderstorm. We will be open, but we will not be able to to up to the observatory if there is a thunderstorm.

Observatory Night for Friday 30 June is on (but we may have a few clouds)

For folks who have reservations for the observatory night this evening, we are a go! Both and Clear Sky Chart are predicting partly cloudy skies tonight.

With light clouds and haze we can still see the Moon and planets, but we may not be able to view deep sky objects. I'm going to open up tonight in the hopes that we'll have more clear sky than clouds, and with the caveat that the seeing might not be good.

We'll get started at 9 PM on the fourth floor of the Science Center in room SC 406. Signs will be posted directing you. We'll go up to the observatory together, see what we can see, and finish up at 10 PM.

Thank you so much for your interest in astronomy and our observatory!

June / July Starmap

The starmap for June and July is here: MCAO June / July Starmap.

I create these maps using the wonderful website and Stellarium software. (Stellarium is a free planetarium software program. If you'd like to know what's up in the sky, I highly recommend it!)
