              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started with heavy large hail around 17:00.  Thunderstorms persisted until 19:00, then some clearing, but radar showed thunderstorms just a few miles from us. Post-storm, the humidity spiked and we ended up in a cloud by 20:00. High humidiy persisted until about 22:30 when humidity rapidly dropped, and we decided to take advantage of that. We tested last night's echelle sag adjustment, then switched over to the guider to do a poitning model (it was not quite photometric enough for throughput). Pointing model was implemented. CU02 used the full time for their program.
