              ------------- ACTIVITY LOG --------------
Observing Specialist:    R.McMillan
First light on the new GFP/IFS!  Successes: focus, instrument block, and
orientation were all very close to what was expected, and image quality
appeared good.  Problems: some motor positions were not well known and
with the CAMAC powered down, various pieces of optics were not held in
place and kept moving randomly into the field of view, making it
difficult to establish the position of the IFS relative to the imager.
Varying clouds contributed to the difficulty, but the clouds also meant
there was nothing more valuable to spend time on.  We finally got some
pretty and useful pictures in morning twilight.
I also did some additional work with testing of the upgraded Agile
drivers and slew stops and supersedes.
