              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Not a great night. Agile needed to be restarted at checkout. Azimuth oscillations were noticeable at (127, 59) and (340, 60).  We had clouds roll in at sunset and things were pretty thick all night making faints object difficult if not impossible.  However, we did have good seeing so...*shrug* that's something.
