Night Assistant:

Problems: 

Telescope control system crashed out and we had to point to zenith after clearing out my exposure queue. In total this cost about 18 minutes. 

Also, the Blue Jeans meeting room that was provided did not work. Blue Jeans is the preferred method of communication for us when we remote observe, but there is almost always a problem. I used Skype with the telescope operator's iPad, and it worked fine. 

We were alerted that the flats for g and VR were not taken before we started observing. Since we used both of these filters, may we have these flats taken in the morning?
