              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Another night of weather indicators crying wolf.  I kept the dome open the whole night, but I did stop and close covers right around the program changeover when I was feeling nervous and there was nothing to see but clouds.
The DIS R400 grating motor was a little flaky and had to be adjusted for both the first and second half programs, but otherwise everything worked well.
