                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Closed most of first half due to humidity. At 22:30 I was tricked by
 what the Sloanies were calling a sucker-split. The humidity dropped
 I started ventillating and opened, 8 minutes later by the time I
 returned to the control room the depression was less than 2 degrees.
 We immediately closed. So when the dewpoint split again grew at 00:20
 I waited about 20 minutes before having the courage to open again.
 The rest of the night went well.
