                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky, G.Saurage (1/2 night)
 Clouds and humidity kept us closed for a couple hours at the start of the
 night.  Humidity spiked above closure limits around 00:30 but I remained
 open until 01:00.  We stayed closed for about an hour after that with the
 humidity on a roller coaster ride.
