              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
TSPEC corrupted images during checkout tonight.  I tried Bill's trick of taking a couple images, but no change.  Since TSPEC isn't scheduled for a few days I left the instrument alone so the Engineering staff can further investigate.
Since we were closed for weather I did some slit rotation tests for Russet.  DIS slit rotation tests (1.5 arc sec slit, 0.4s, Br. Qrtz.)
Clouds and the threat of the dark clouds on the satellite, just to our west, kept us closed all night.  We called it at 04:00.
