              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Huehnerhoff
Light rain in the afternoon with clouds dissipating slowly in evening.
Delayed opening due to local radar with clouds over site.
Tertiary error while slewing to first target, 0300UTC (was not seen during
checkout).  When switching from ECHELLE to DIS the tertiary actuators
stopped responding.  Changing instrument to something different then
returning to original configuration fixed this problem.
