Problems: 

We had issues with the AOS focus system at the beginning of the night.  It appeared dz corrections to the hexapod were applied with the incorrect sign, causing the focus to repeatedly diverge.  Problem was solved around 11:10.  Also, the desktop manager on observer1 crashed while we were troubleshooting this problem- had to reboot the machine to get the desktop back.
