              ------------- ACTIVITY LOG --------------
Observing Specialist: M.Croom
Threatening radar delayed opening until 1 hour prior to the end of A Half. Pollen counts were made throughout the night and discussed with Sloan, and we both decided to open with the relatively low pollen counts after the radar was no longer a factor. ARCSAT had a dome/weather-listening fault right as B Half joined. Fortunately, Jack was online and he corrected the ARCSAT issue while I focused on 3.5-m B Half startup activities.
No issues with the 3.5m tonight.
