16:38 UT I just turned on automatic SK flagging of RFI. We will see what problems it creates...
It was windy all day, so no calibrations could be done. The calibration for the following day (Jan 21) was written to the SQL database at 2018 Jan 20, 14:00 UT.
We had a power outage at around 15:10 UT, lasting until a few hours later.
19:35 UT Kjell modified Ant 1 DCM to add an optical attenuator, in an attempt to reduce the sensitivity of baselines with Ant 1 to air conditioning cycling. I will check the results after some time has passed.
00:10 UT Delays were reset except for ant 6, which I (Natsuha) couldn't find good delay center. They were found to have not been reset following the power outage on Jan 22.
