Because of the weather, my recommendation is that folks avoid driving and stay home tonight.
If you do wish to visit MC this evening, I'll be here with a few of the astronomy club students in the Science Center building, room SC 406 on the fourth floor from 9-10 PM.
I also want to take this opportunity to let you know my colleague Dr. Harold Williams at the Takoma Park / Silver Spring campus will be hosting an event for the Mercury transit on the morning of Monday 9 May 2016. Details can be found here: http://www2.montgomerycollege.edu/departments/planet/
Thank you so much for your interest in astronomy and our observatory!
