                ------------- ACTIVITY LOG --------------
 Observing Specialist: G.Saurage
Overcast skies, high winds, high humidity. Running on generator power exclusively.
Observing cancelled.
Generator has been shutting down; requiring a restart several times. Most of the
telescope systems were taken down gracefully in the afternoon/evening and the
telescope was stowed at zenith in case we lose air. Gravimeter compressor switched
off as per T.Murphy's instructions. APOLLO has not been drained yet; if power is
still questionable tomorrow it probably should be.
