              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started out with clouds and threat of rain.  However, we attempted to open, as the clouds were visibly clearing.  Unfortunately, while we were open, neitherDD04 or APO1 were able to get any photons.  CU03 had better luck and was able to get some good date.  Humidity spiked near 1am but we were able to stay open for the rest of the night with excellent seeing.
No problems tonight and I did not hear the clunking sound from the left dome door that I hear last night.
