Problems: 

No major problems to report.  The guider GUI started acting buggy at around UT 04:20.  The 4 guider images would not refresh.  Tried to refresh the browser a couple times but didn't help. The centroid evolution plot did refresh regularly. At UT 08:40, SISPI GUIs crashed. Claudio was able to reload them but they immediately crashed again.  Claudio reloaded again and this time it worked.  No time was lost from either issue
