Problems: 

Mauricio rebooted and power cycled the crates before the night started, due to problems with the PSL role.  He did this quickly and efficiently, so no dark time was lost.

Strange telescope jump in image 205624 and also image 205776.

We had one interlock error that was fixed by reconfiguring.

The guis froze, and when refreshed, the observer console had an exposure history that was not sequentially in order.  So we closed the guis with the big red circle button and restarted them.  This made the observer console look normal again.  However, we had the "master console holder no longer exists" error.  I vnc'd into sispi and released the master console to solve this.

The guider failed to pick up guide stars 13 times tonight.  These guider issues only occurred when we were observing our crowded fields.  (Tonight we did not decrease the guider exposure time, as there was slight cirrus in the sky.)

Comments: 

Great night!  Tonight we especially marveled at Rasicam.  It was interesting (although heart breaking) to see the light cirrus move around the sky tonight.  We had 1" seeing despite the cirrus, and the clouds were never thick enough where we had to stop observing.
