              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Very strange and unstable weather tonight.  We did have a period with low
humidity and thinning clouds when we were able to open and the first-half
observer got some useful observations on bright targets.  Then the clouds
irised in from all directions at once.  APOLLO was never able to range but
did get some important calibration checks done after recent work on the
laser, before standing around for a while staring at the sky.
Meanwhile, a storm started over El Paso, grew surprisingly strong, and
traveled north up the Tularosa basin, avoiding the mountains - all very
strange things for a storm to do in the middle of the night.  Second half
was lost to nearby rain and lightning with high humidity, but we didn't
get any rain at the observatory until 04:30.
