              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Triplespec continued to showed the amplifier light.  After Eilat Glikman began taking exposures corruption in the images were noticed.  We changed to DIS and  attempted to open the dome at 20:25 but closed 5 minutes later due to too high humidity. I never gave tcc control to Eilat.
High humidity continued for the rest of the night and we were not able to open.
