              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
It was a dark and stormy night... Lots of rain, all the rain. Clouds, fog, rain. No hope of opening. The puddle by the echelle was much smaller today but I still wasn't going to risk opening the mirror covers.
No problems tonight.
