              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Echelle read out all zeros while UW05 was taking calibrations. I reset the echelle in the icc and it was fine.
There were thunderstorms all to the east and stayed that way. Some clouds did roll in at sunset and lingered for a bit. Once it cleared up the seeing was moderate. At one point, when the wind shifted, it went above 2".
