              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shelden
01:10 Closed for a large and very surprising dust spike.  We checked the sky (which looked clear) and verified with the handheld dust counter in the Sloan room, which agreed with the normal dust counter.  So I closed, especially since it continued to climb.  Reopened at 03:52.
At 04:15 the ecam shutter became stuck.  I called Joe, and we tried restarting the camera and tested multiple stars but it won't open.  I went up and watched the shutter while Joe took exposures, and it never moved.  The rest of the night was lost.  We called Bill as well.
