              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
There was rain just east of the observatory two hours before sunset, but it disappeared quickly and we had clear skies and good seeing until about 4 am, when a few clouds moved in and then had a party with all their friends and really not enough interpersonal distancing.  That plus some radar echoes persuaded me to close right around the beginning of twilight.
NICFPS needed a restart of the instrument control software right after mounting, but after that it only gave a few bad images before settling down, and then a couple more at the end of the night.  But check out the near-record seeing, which was delivered for some of the science images as well.
