              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Bradley
Seeing started out bad, but settled down nicely soon after the start of the night.  At the beginning of second half, some hazy clouds rolled in.  Seeing went up to around 1.5".  Heavier clouds rolled in towards the end of second half, but we pushed through them.
