                ------------- ACTIVITY LOG --------------
 Observing Specialist: W.Ketzeback
 Cloud cover and threat of rain kept us closed until 2340. At 0330, the
 observer reported that they lost sight of the slit and stars in the dis
 slit-viewer. After a few short minutes it was discovered that the na2
 eyelid was closed. I attempted to reopen it remotely but that failed.
 I switched it to manual mode, and got the observer back to taking data.
 Seeing was variable and mostly poor throughout the night with winds
 parallel to the ridgeline.
