Hartebeesthoek (Jonathan Quick at Tue Oct 21 18:44:56 2014) Minor failures:RECE

Receiver partially warmed up during experiment due to an electrical breaker failing and then re-cooled once power was restored to the helium compressor. No other known problems

Yebes (Daniel Sastre Walter at Tue Oct 21 20:07:09 2014) Minor failures: RECO

Some problems to record properly from scan 38 to scan 43

Onsala (Jun Yang at Wed Oct 22 06:26:06 2014) Minor failures:

The first 10 minutes were out due to a change of antenna gearbox. Proper Tsys data were not available until the noise source were reset to normal MK4 calibration mode. At 9:15 UT, there was an error: ERROR sc -24 setcl: Mark 5B syncerr_gt_3. CONSIDER using fmset 's' option to fix. I tried to run fmset for a few times, while, MK5B was busy and refused to sync time during the gap (no recording).

Jodrell_Bank (Jimmy Cullen at Wed Oct 22 08:22:26 2014) Failure: WIND

Observation missed due to high winds

Torun (K.Borkowski at Thu Oct 23 11:27:07 2014) Success:

No known problems.

Onsala (Jun Yang at Mon Oct 27 06:59:03 2014) Minor failures:

Switching on and off noise source had a long time delay (~20 seconds) in the first hour and so there were no Tsys measurements. After that, the bug was found and fixed by our software engineer. There was an error: 2014.294.09:15:50.22?ERROR sc -24 setcl: Mark 5B syncerr_gt_3, CONSIDER uisng fmset 's' option to fix. According to its suggestions, we tried to run fmset to fix it during the gap for a few times, while MK5B reported too busy to service request.

Effelsberg (Uwe Bach at Tue Oct 28 13:04:00 2014) Minor failures: WIND

There were two stops due to high wind at 15:00-15:30 UT 18:40-19:55 UT
