              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Tonight was a lovely night with clear to photometric skies and good seeing.  PAO was able to observe multiple science targets down to the diffraction limit of 0.1 arcsec. (!!)
ARCSAT was having trouble again, which was very sad on such a nice night.  But this time, with some help from my husband, Bill and I were able to determine that it's a real problem and not just that I was too busy to spend time in the other dome.  If the problem is a blown fuse it might be fixed tomorrow; if it requires parts to be ordered, ARCSAT might be down for a few days.
