Onsala (Jun Yang at Tue Jun 15 07:57:26 2021) Failure: ANT

No observations because of a failure of the antenna declination encoder.

Yebes (Javier Gonzalez at Fri Jun 18 12:06:40 2021) Minor failures: TSYS

No amplitude calibration due to noise diode failure. We have measured Tsys manually with hot load after the schedule at 4 elevations: 88, 65, 45, 20. Results appended to the logfile. Antabfile manually generated using gain tracking (AGC deactivated during recording) and reference calibration at elevation = 45 degrees.

Westerbork (Blaauw at Wed Jun 23 12:09:32 2021) Success:

Jodrell_Bank (Alastair Gunn at Fri Jul 02 13:51:01 2021) Minor failures: ANT

Lost first 2.5h of observation (on source soon after 0600 UT) due to problems with antenna control. No other known problems.

Tianma65 (Bo Xia at Tue Sep 14 12:10:33 2021) Failure:

didn't observate due to the national task.
