                 ------------- ACTIVITY LOG --------------
 Observing Specialist: Jack Dembicky
 I started cooling fans and opened the louvers at 18:35 tonight. I closed
 the louvers/turned cooling fans off at 19:55 since the skies were not
 looking promising to open anytime soon.
 Clouds remained all night long with the occasional sprinkle to set the
 rain sensor off so we remained closed.  We also had a couple dust events
 during the night.
