                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Nicfps readout crashed in the middle of the first dither pattern this evening.
 ICS was rebooted and restarted. Downtime was under 5minutes.
 Some more detailed examples of the image elongation and Acceleration Limited
 messages were sent to Russet at the end of the night. The Acceleration Limited
 messages on AZ and/or ROT during an exposure do appear to be a persistance
 of the warning message after an offset as the chip is clearing rather than
 during the integration but still further investigation is most likely needed.
 Seeing was variable all evening between fair and sub-arcsecond to horrific at
 greater than 2 arcseconds.

     used is north=0 degrees, east=90 degrees.  The dust count is
     particles > 1u per 0.1 cubic feet.
