Failure of the two main breakers for the Glycol Chillers/Pumps at 23:40. Three hours later we are running the LN2 system on the air-cooled compressor only. We are extremely short of LN2 in the Linde tank one full tank at the C floor. DECam tank at 71%, heater off. Crates 1,2,3 off, top cap of telescope off, at NW platform, open lower shutter opposite, maintaining 35C. Computer room with two big fans, all access doors to G floor open, rack doors open. Trying to avoid warming DECam up, without melting everything else.

Diego, Hannah and Marco worked on debugging why the new readou6 machine will not produce believable AO results. They made good progress and found missing libraries that were installed. Tests were terminated by the Glycol failure.
