EC070F2020-02-22UweMinor failures, , , , WIND, , , , , , , , , , Started one hour too late, because of high wind speeds. Wind stayed strong during all the observations.

EC070H2020-02-23UweSuccess, , , , , , , , , , , , , , Strong wind at the end (last hour), but kept observing.
N20Q12020-02-24UweSuccess, , , , , , , , , , , , , , Observed with different LO than given in the schedule. New LO 42400 MHz. Applies also for user observations. Weather was really bad, lot of rain and wind.
GA043A2020-02-25UweSuccess, , , , , , , , , , , , , , Unfortunately the weather was really bad, lot of rain and wind.
EC070H2020-02-23UweMinor failures, , , , WIND, , , , , , , , , , Sorry, did not keep observing. stopped at 8 UT, because of the wind.
GA043A2020-02-25UweMinor failures, , , , WIND, , , , , , , , , , Stopped observing because of high wind from 12:30 to 13:30 UT and 18:10-19:46 UT.
N20C12020-02-25UweMinor failures, , , , , HIGH, , , , , , , , , When switching the source in the middle of the observations the DBBC lost somehow the calibration on IFC. All LCP data shows an enormous increase in Tsys and huge spikes: e.g. http://old.evlbi.org/tog/ftp_fringes/N20C1/scan08/st04_lcp-st04_lcp-ch0-lsb-0-2_large.png Reason not understood yet.
EM141A2020-02-26UweMinor failures, , , , , , , , , , , , , , Stopped observations at 0:55 UT because of snow fall. Lost about the last 30min.
EC070I2020-02-26UweMinor failures, , , , WIND, , , , , , , , , , Had to stop observations from 4:40 to 5:40 UT because of snow fall.

EC070L2020-02-28UweFailure, , , , , , , , , , , , , , Not observed because of snow fall. Snow stopped at some point, but because of the wind some snow was blown into the dish and the dish was too heavy to be moved.
EM140B2020-02-28UweMinor failures, , , , WIND, , , , , , , , , , Started late because of snow stop. On source at 7:18 UT.
