              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Another lovely clear night - with meteors!  During the day, Bill re-leveled the telescope, undoing the changes from Monday night.  I reverted the pointing model back to where it was last week and pointing was pretty good (even with APOLLO!) if not quite the best we can do.  It can wait until the next observing time, so we won't need to pre-empt anyone.
After that it was all clear sailing.  The dcam shutter stuck open, but the ecam shutter behaved tonight.  Last night it was the other way around.  Go figure.
