                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 First half we were clouded out.  I spent the time trying (in vain) to get
 my web creation software to directly talk to our web server.
 Second half looked more promising with the system apparently mostly
 dissapated, but not dissapated enough.  Clouds came and went and then
 came back a few minutes later.  It was a check outside every 15 mins to
 see if things had improved enough to open or not.  The cloudcamera was a
 bit deceptive as there were large masses of clouds just outside its field
 of view that kept sending more our way during the night.
 Finally around 03:25 it looked promising enough to actually open.
 No problems with the telescope.
