                ------------- ACTIVITY LOG --------------
 Observing Specialist: G.Saurage
Thunderstorms in the early evening dramatically cleared off in time to open, but
after a few hours the cloud cover was substantial enough to prove unusable. We
closed when we weren't getting any data. The clouds continued to come and go during
second half, but with bigger clear gaps. Clearing at twilight.
No problems.
