                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 Storms to our west (with virga falling) could be seen at sunset.  I held
 off opening until conditions looked better.
 Clouds rolled in around 21:40 and closed us down until midnight.  We
 re-opened around midnight for an hour until a thunderstorm brewing to our
 west moved over us.  It rained for about an hour with thick clouds until
 04:30.
 We had some NA2 guider problems as well tonight.  Fritz spent a couple
 hours figuring out what was going wrong and fixed the problem.
