              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
TSPEC images looked back to normal during checkout today.
I took images with TSPEC at random times during the night to see if the instrument behaved, All images appeared to be fine until the last one of the night, that one was corrupted again.
A nice night once the clouds went away a few hours after sunset.
