                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Delayed opening because of high winds, blowing snow and humidity.
 Once we did open seeing was horrific even in the near IR because
 of a strong wind from the NE blowing turbulent air across the
 ridge. Seeing remained greater than 2 arcseonds until after
 midnight. The tertiary rotation worked fine during checkout
 as well as to and from the APOLLO observations tonight.
 Conditions again forced us to close at 0200. Dewpoint depression
 was over the limit for the rest of the night. We gave up at
 04:45.
