              ------------- ACTIVITY LOG --------------
Observing Specialist:    J.Huehnerhoff
Moderate clouds at start of night increasing shortly after sunset.  Even
though the telescope was open no science was possible till 2230MT.  Clouds
cleared by 2300MT but started to build back up at 0330MT.  Reopened at
04:45MT when the clouds thinned enough to get a science image.
ecam continued to behave oddly.  The camera appears to be reading out a
delayed image which results in the current stars position to be different
from where it was in the last image.  Caused problems with the remote
user.
