The telescope and facility are looking and working great. Thanks!
The dorm rooms and comedor are in th best shape I have ever seen. Very well done.
We really should get TASCA movies going again during the night. They are very useful for clouds.
The last two nights, the M1 temperature has been excellent wrt the ambient. However, the DIQ on DECam has been significantly worse than the DIMM seeing. There was little wind last night and the vents are closed tonight. At airmass 1.57, pointing south, the DIMM gave 0.8'' while the g band seeing was 1.45''. Guiding issue? I am watching centroids on Guider pane and there are large +/- 0.5'' errors which look to be damped when sent to TCS.
