              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Echelle checkout image looked dim/non-existent, but after manaully taking a flat then a re-run of checkout script it was fine. A storm blew in at the exact time dome checkout was being performed. A sudden gust caused an enclosure collision. I reset the enclosure controller, checked the collision sensors and I slewed back to 104,10. I did not want to risk more az slew tests in those conditions. Rain started at 18:45. It was finally safe to open around midnight. Around 03:00 returns began to appear on radar. They worsened, and around 03:15 we closed again. We did not open again.
