              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Heavy clouds and threat of rain all night, with a few short periods of actual rain.  I did not have trouble during test slews but did not test extensively.  Echelle has been cooled and appears okay, hopefully it will remain stable.
