                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Closed all night due to weather. I worked on a long standing request by
 J.Holtzman to study image quality improvements by simulating a tip-tilt
 system using shift and add techniques on some of the fastcam data. Initial
 results were sent to Jon. The only problems tonight were spurious ground
 fault trouble alarms in the Sloan Support Building on the site fire alarm
 system.
