                ------------- ACTIVITY LOG --------------
Observing Specialist: G.Saurage
Clear skies and high winds. The winds shut us down at 21:00, we re-opened
at 23:20 when winds were only gusting 32mph (down from 44mph). Continued
high winds most of 1st half.
Winds were reasonable 2nd half, but seeing was pretty poor. Conditions
seemed to finally stabilize at about 4:00. Seeing improved a little. SN
observations were collected without any problems.
