                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 The sky was promising at sunset, but several waves of light
 precipitation moved through and took up all of first half.  I did
 some closed-dome tests of tracking with dither scripts in possible
 trouble spots, which looked good.  During second half, the
 precipitation finally dissipated and we were able to get on sky.
 Seeing was quite bad at the time of focus but eventually came down
 to about 1.5 arcsec, which wasn't too bad considering the unsettled
 weather.  Everything worked well while we were open.
