                ------------- ACTIVITY LOG --------------
 Observing Specialist: R. McMillan
 Threatening weather nearby kept us closed for the first few hours of
 the night.  Conditions improved just as the moon was getting high
 enough to be useful to APOLLO.  Unfortunately, although skies were
 mostly clear, the seeing was quite bad; the greatly reduced any
 return signal from the moon, so once again there was no unambiguous
 detection.  More rough spots were smoothed out, though, and the time
 was generally useful.
 The NIC-FPS observations during second half were more frustrating,
 as readout was only working on one channel; tomorrow during the day,
 there will be a search for a loose lead.  For tonight, there were
 more measurements of the newly-adjusted slit position, but minor
 difficulties continued there as well.
 The TUI-based guiding software has apparently been messed up by a
 change made to fix another problem noted last night.  I was able to
 run with the old TCC-based guiding algorithm, instead.

     Note: the wind was coming from the azimuth listed.  The convention
     used is north=0 degrees, east=90 degrees.  The dust count is
     particles > 1u per 0.1 cubic feet.
