              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
Check cables error on omea, rebooted alcor computer.
We had some light rain in the afternoon, and then a lot of clouds and some threatining radar for most of the night as the storm sat just east of us. When clouds started to clear up, dust counts went up due to wind from the southeast. We did not open.
