              ------------- ACTIVITY LOG --------------
Observing Specialist: H.Abbot,T.Sutherland

High pollen counts kept us closed all of A-half. Counts went down and was able to open for most of B-half.

Corrected pointing of Arcsat post-zenithing. 

Echelle still taking a very long time for fill sequences, but at least it's not draining LN2 from the nurse tank continually. Otherwise instruments and telescope all well behaved tonight.
