                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
01:27:18 - 01:2728 Wind pushed telescope in Altitude and altitude drive released, telescope
free-slewed to hard upper limit (about 30 deg).  We were facing into the wind with gusts around
30MPH
01:51:40-01:51:50 Alt drive released again, 30 MPH gusts and pointed directly into wind.
Telescope was at about 70 deg alt. and tracking, I was still trying to focus.  I had the observer
move to another target not facing the wind.
Clouds moved in around 21:00 and closed us.  They stuck around until around 03:30.  We re-opened
at 03:50.
