                ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st Shift: Russet McMillan
 Clouds and high humidity kept us closed all evening.
 Observing Specialist, 2nd Shift: Jack Dembicky
 Lt. Freezing rain around 1AM and Fog/Humidity/clouds all night long
 prevented any real chance of opening tonight.  Dome is facing due S to
 help melt any accumulated snow/ice (snow program is NOT running).  Filled
 Echelle LN2 tank this morning as well.
