              ------------- ACTIVITY LOG --------------
Observing Specialist: N.Ule
Heavy clouds and some rain kept dome closed until 22:20. Began on-sky
pointing model but could determine no fault in the telescope's pointing.
 First observers managed to get on sky briefly before clouds came back.
Second observer used NICFPS and noted that some images were partially
corrupted for reasons unknown.  Ex.
/images/Q3UC04/UT110813/20110813.0010.fits[0].  On other images observer
noted that left and right side of the chip would report different number of
counts.
When NICFPS was upside down, received a "bad environment" indicator and an
error report from the pressure sensor, pressure was slightly too high.  The
rotator problem may still persist.
Third observer reported no problems.
