              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We had some unusual weather; once the afternoon storms had passed we opened for a few hours, only to have more storms pop up all around us shortly after midnight.  They gave us some rain, then passed away and let us open again.
We encountered the mystery shutter issue on the DIS slitviewer for a while, but it didn't interfere with guiding and eventually it went away again.  This will be a target for further diagnosis during upcoming engineering.  Otherwise, everything worked well.
