Also Present:

Problems: 

19:50 connection between SISPI (observer1) and observer 2 was lost because observer2 was rebooting itself this afternoon, so we had to restart SISPI to reconnect both machines.

12:04-12:21 DECAL problem. We restarted the machine because it was unresponsibe.  SISPI did not crash this time and a new sound alarm was heard, a sheep complaining.   We took a zero after the DECAL machine was restarted and the filter stayed in the g-band position instead of the block position.  

12:29 occlusion problem with image 745744

3:35 occlusion problem with image 745799

5:58 no guiding
