              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Bradley
Wind calmed down enough to try opening, and seeing was downright awful.  The 3.4 that I recorded was the minimum, and it was variable up to six arcseconds.    You read that correctly.  SIX!  The wind forced us closed after only an hour (not that we were getting anything).  Wind stayed very high for all of first half and part of second half.  We also had blowing snow.  I reopened at 02:30.  The wind stayed down for the rest of the night, although the seeing was still terrible.
