              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
For most of the night we had clouds, rain, and threat of rain to keep us closed, along with occasional high winds and borderline dust.  Right at the start of morning twilight, conditions improved and we were able to open to get a small amount of usable data on a bright target.  So it wasn't a complete loss.  I did not record focus values since I was just adjusting focus by eye.
