Jodrell_Bank (Eskil Varenius at Mon Oct 22 12:05:26 2018) Minor failures: TSYS POIN

No known issues apart from general session feedback i.e. pointing and Tsys.

Cambridge (Eskil Varenius at Mon Oct 22 12:10:20 2018) Minor failures: RECO TSYS POIN

Using Cm for eMERLIN outstations feedback. All stations had recording issues until about 0945 when only ever 4th scan was recorded. This because of VEX-to-eMERLIN conversion bug for experiments scans without any gaps in between. The bug was fixed 0940 UT. Kn carousel issues, no usable data. Pi control code issues, usable data possibly only last 20 minutes. Da may have delay/phase jumps due to ADC timing issues. De, Cm in principle works OK except for recording issues.

Effelsberg (Uwe at Mon Oct 22 12:41:37 2018) Success:

Onsala (Jun Yang at Mon Oct 22 14:44:10 2018) Failure: WIND

Due to the strong winds, the telescopes stowed automatically before the observations. There were no useful data.

Noto (Andrea Orlati at Mon Oct 22 14:48:41 2018) Failure:

Did not observe due to receiver failure.

Shanghai (Bo Xia at Tue Oct 23 00:33:25 2018) Success:

Urumqi (Peng Li at Tue Oct 23 13:23:24 2018) Success:

Torun (Pawel Wolak at Thu Oct 25 10:23:43 2018) Success:

Kunming (Li Zhixuan at Fri Oct 26 08:12:45 2018) Success:

Onsala (Jun Yang at Fri Oct 26 11:54:55 2018) Success: WIND

Observed for some scans at night, while no useful data because the antenna was stowed automatically due to the strong winds.

Westerbork (Blaauw at Tue Oct 30 18:40:55 2018) Success:
