                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Elevated dust again tonight however we were able to remain open
 using the press fans to keep dust levels in the dome within
 acceptable specs.
 Nicfps started reporting all 0's in the middle of a long dither
 pattern. About 30 minutes of data was lost before the observer
 caught it. I was busy at the time troubleshooting the echelle
 which had started to warm inadvertantly. Both problems were
 corrected. I reset nicfps with an expose init and I forced
 a fill sequence on the echelle.
 No other troubles tonight. Seeing was moderate to poor in the
 NIR at 1.1 - 1.3 arcseconds but still a far cry from the >2
 arcsecond measurements the 2.5m observers were seeing next door.
