              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Getting back into the swing of things over here. Due to the warm dome this afternoon, DIS started heating up and Bill had to raise the warning temperature. The red side wasn't reading out correctly and the power supply needed to be restarted. After that, no more problems. It was taking me awhile to get the DIS wavelengths properly centered. Finally realized I needed the Argon lamp!
I noticed the counter weight was off by 20000 when I went to adjust the weight from ARCTIC to DIS. However, the range between upper and lower (~2000) remained the same, it seems like the displayed values were just off by 20000. I sent a PR.
We had clouds with virga and rain nearby but it never reached us. The seeing was great all night!
