              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
My 3rd observer notices a low level noise pattern in the TSPEC images.  I examined some images from last April and the noise was less.  PR submitted for further investigation.
Winds shut us down at 04:10 tonight.  Gusts stayed above closure limits and my observer gave up at 05:30.
