              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
DIS was misbehaving. Fortunately, today it only took 1 init to make it behave. Bill's dome setup may have helped, it was not as warm today on the int level. We started with storms to the north of us. Rain by 17:00. Rain stopped, but thunderstorms remained on our doorstep for several hours. Big temperature drop around 23:00 which pushed the RH over safe limits. Humidity dropped as another thunderstorm formed over us around 00:00. Rain began shortly after. Hudidit spiked again after 01:00. Heavy rain and storms by 02:00. We did not open at all.
