              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started with high haze but calm. Seeing was good. Clouds and haze blew out around 21:00. Nicfps was returning 0s in images when we did the swtichover (it was fine during checkout). A nicfps init fixed it. At 01:00 nicfps experience the same error, same solution. Happened again at 05:30. Same error, same fix. Happened again at 06:20, ditto. We were open all night.
