Onsala (Michael Lindqvist at Sun Jun 5 06:46:50 2005) Minor failures :
1. Rather bad weather, rainy from time to time
2. Mark5 hanged, day 154, around 17 UT, lost about 30min
3. According to scan_check (in checkmk5a) there might be problem with the scan (note the "?"):
4. RFI ==> Bad tsys in a few cases.

Torun (K. Borkowski at Mon Jun 6 07:29:57 2005) Minor failures : PCAL
Last 8 hours (since 22:10 on day 155) lost because after crash
of one of computers the operator failed to properly set attenuators.
Also, there was no phase-cal signal during this experiment.
Westerbork (Tony Foley at Mon Jun 6 11:54:57 2005) Minor failures : WIND
Wb used in phased array mode.
AAAAARGH I overwrote the log file by a typo
We also had RTC in the array from 06:30 to 09:56 on Friday
(The PI requested both RTC and RTD out)
On friday evening (16:32) on of the telescopes had a reset caused by
nearby lightning strike - so it was out for a few minutes.
Effelsberg (A. Kraus at Tue Jun 7 09:00:35 2005) Minor failures : WIND TSYS SLEW
Thunderstorm: stopped UT1615-1655 (June 3rd). Most Tsys measurements lost due to inadequate slewing time.
Hartebeesthoek (Jonathan Qcuik at Tue Jun 7 09:40:05 2005) Minor failures : RECO RFI
The Mark5A failed to record correctly after an automatic bank switch at d154 23:33 UT though the record pointer did increment - the FS only giving an error at disk_record=off at 00:15 UT. Mark5 manually rebooted and recording restarted at 00:45 UT. Intermittent RFI throughout experiment

The Lovell Telescope was used.
No known problems.
Cambridge (Alastair Gunn at Thu Jun 16 10:32:59 2005) Minor failures :
