              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night was at level cockatiel.  There was much dust and things were rather flighty.  The wind crested to nearly 50mph and we were left grinding our beaks over the situation. NM04 only managed to clutch their standard stars and nothing else.  CU06 had a little more luck on their first night of training and preened themselves pretty with 3.5 hours of exposures.  Seeing was moderate due to all the dust.
No problems tonight.
