               ------------- ACTIVITY LOG --------------
 Observing Specialist: J. Coughlin
 Az Velocity Scale was 579.9, measured 574.9, 576.9; 575.9 changed to 576.0
 Clouds were thick before sunset, but were mostly cleared out by twilight,
 so we were able to open on-time. Light to medium clouds rolled in and
 out for most of the night, but useable data was obtained by both programs.
