              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Huehnerhoff
Mostly clear night with moderately good seeing.  Clouds coming from the
east appeared at 04:30MT.  They left as quickly as they arrived and left
enough time to reopen and get the required data for the last program.
