               ------------- ACTIVITY LOG --------------
 Observing Specialists: J. Davenport
Was able to open at about 10:45 and stayed open the rest of the night!
2nd half users noticed problems with the DIS guider. It started guiding
when they didn't ask it too, and the corresponding images in the guider
directory are missing (proc-d0231.fits, for example). We didn't try to
figure this out since the guider started behaving normally again right
away...
We were able to take our throughput measurements on BD +28 with low-res
gratings! Look forward to seeing the improvement after shutdown.
