Yebes (Isaac Lopez-Fernandez at Wed Mar 17 12:36:34 2010) Minor failures: LATE

Problems with the first operator. Observation started at 08:03;38. All sources before that were lost. Fine weather. No other problems.

Effelsberg (Uwe Bach at Wed Mar 17 13:21:52 2010) Minor failures:

A few scans were lost because of problems with the antenna control. Happened around 2:30 UT and 9:40 to 10:30 UT

Medicina (Morsiani at Wed Mar 17 14:08:26 2010) Success:

Onsala (Michael Lindqvist at Wed Mar 17 15:44:16 2010) Minor failures:

Antenna stowed due to wind between 4-6 UTC. We also (again!!:-() had problems with the Mark 5 (when switching to an partly recorded pack). Have a look at the log, e.g., the scan_check, very confusing??!! Then (8-12 UTC) we got some of errors "MARK5 return code 6: inconsistent or conflicting request" but the scan_check looked OK. Not sure if the operator noticed the errors.

Shanghai (Bo Xia at Thu Mar 18 02:53:08 2010) Success:

Torun (K. Borkowski at Thu Mar 18 09:15:19 2010) Minor failures:

Due to short outage at 6:23 we observed off source till 7:00 UT. However, at the experiment end it was noted that the LO was set to 5901 MHz instead of 5900 MHz. We cannot tell whether it was so during the entire experiment or after the outage. We fear the whole experiment had this 1 MHz offset (for prior to the exeperiment we carried out observations with just such value of LO) and suspect similar situation may have happened a few times in the recent past when JIVE reported no fringes to some experiments (in June and October 2009 sessions and on 1 Feb 2010). This would suggest the lo= command issued by our FS may not get executed properly. The problem is being investigated.

Westerbork (Geert Kuper at Thu Mar 18 19:31:55 2010) Minor failures:

Only RT7 in array. Due to backend problems scan 7-13 were lost. No data from 00:56 UT - 01:34 UT

Noto (P. Cassaro at Fri Mar 26 09:32:39 2010) Success:

Jodrell_Bank (alastair gunn at Mon Mar 29 12:18:22 2010) Success:

No known problems.

Cambridge (alastair gunn at Mon Mar 29 12:19:19 2010) Minor failures: ANT

Modem failure between 02:58 and 03:16 UT. No other known problems.
