              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started out clear but with only moderate seeing due to a northern wind. Seeing improved as the night progressed but CU01 was cursed with clouds during their transit. Only while the planet was in transit, mind you, it was clear during all the baseline data! Sigh.
No problems tonight.
