              ------------- ACTIVITY LOG --------------
Observing Specialist:    J.Huehnerhoff
Light to moderate clouds throughout the night.  Radar returns threatened
to move into the local vicinity but dissipated as they passed nearby at
0400MT.
Agile collimation data taken during morning twilight.  Collimation looks
good based on this data.
Standard slitmask put back in DIS, mask files updated.
