              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Huehnerhoff
Poor seeing with clouds at start of evening improving throughout the
night.  While closing at end of the night it was noticed that the altitude
brake was not engaging, see PR1259.
Clouds interfered with some of the engineering tasks but much was completed.
Checked echelle interorder light (12.9).
Verified NICFPS is still failing upside down.
Restarted Nimble and AgileICC.  NTP client error on startup, no further
problems after image was taken.
Zeroed the NA2 rotator.
Pointing model taken and implemented.
Collimation checked with AGILE and SPICAM.  Collimation looked good.
Fastcam data taken.
SPICAM throughput measurements taken.
DIS spectrograph focus checked against slitviewer focus.  25 micron
difference noticed.
SPICAM standards taken at different CCD temperatures.
