              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
During the afternoon while NM07 was taking their echelle calibrations, the instrument read out all zeros. This was in the middle of a cal series. I restarted the icc and all was good.
The night started clear with good seeing and we had no problems! A lovely night.
