Onsala (Michael Lindqvist at Fri Oct 28 13:12:54 2005) Minor failures : WIND
We had to stop observing at 07:40 UT due to high wind speeds.
Medicina (Andrea Orlati at Fri Oct 28 13:15:44 2005) Minor failures :
Antenna was not tracking the sources due to an error in Antenna Control Unit configuration. Problem fixed at 0:30 UT.
Effelsberg (A. Kraus at Fri Oct 28 14:43:38 2005) Minor failures : FORM RECO
Severe formatter communication problems all through the experiment; unclear how this affects data quality. Several attempts to improve the situation (check communication or use spare formatter) did not work (but led to a loss of a few minutes of data each time). Due to a Mark5 failure no recording was done between UT2326-2346 (reboot was necessary). Some RFI in the lower bands.
Torun (Kaz Borkowski at Mon Oct 31 07:06:12 2005) Minor failures :
Around 1:30 UTC BBC5 lost 1pps and remained so throughout the rest of this experiment (later this bbc unit has been replaced for a spare one, so that the following exps are not affected).
Westerbork (Tony Foley at Mon Oct 31 08:40:41 2005) Minor failures :
Wb phased array (ZP).
Bad RFI about 1620MHz. System restart lost
array from 01:43-01:50UT
Jodrell_Bank (Alastair Gun at Tue Nov 1 12:23:03 2005) Success :
The Lovell Telescope was used.
No known problems.
Cambridge (Alastair Gunn at Tue Nov 1 12:24:07 2005) Minor failures : ANT
VLBA rack was running with failing PSU from the start, which
may have resulted in unlocked BBCs. It was almost certainly
dead by 09:30 UT and was taken offline at 11:43 UT for repair.
Schedule was left to run with no valid data.
Robledo (Esther Moll at Wed Nov 2 14:34:03 2005) Minor failures : HIGH RFI POIN
VC#5 (294.49MHz) degraded by L-band known RFI. VC#1 (230.49MHz) and VC#3 (262.49MHz) were less affeted.
Due to a encoder problem, the antenna was operated in computer mode instead of the usual mode. Pointing was checked before the observation.
