               ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 We had heavy clouds at sunset, with rain and fog a little later.  We
 were able to open just at midnight as the edge of the cloud system
 approached, and the visiting instrument team got a little data at
 high airmass and poor seeing.  For second half, seeing started out
 poor and improved somewhat, but a chunk of time in the middle of the
 morning was unusable due to clouds even though the telescope stayed
 open.
 Everything worked well.
