                ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st Shift: Russet McMillan
 Persistent high clouds kept the telescope closed for most of first
 half, until I gave in and chased a sucker hole, gaining lots of cloud
 flats and a few foreground stars, but not much of scientific value.
 I did manage to confirm that there was no gross coma, at least at
 NA2, so the effects noted last night were probably a result of high
 airmass.
 Observing Specialist, 2nd Shift: Jack Dembicky
 Clouds kept the telescope closed the 2nd half of the night.
