Experiment Feedback
Medicina (Sergio Mariotti at Fri Nov 19 10:44:20 MET 1999) Minor failures
NO scans lost.
Sometime, few seconds pointing off due short blackout of Main Electrical Power.
Weather rain, snow, wind.
RFI on band
Torun (K.Borkowski at Fri Nov 19 10:54:57 MET 1999) Minor failures
No problems noted until 6:05 of day 323. Then, a power failure
caused a damage to a few sensors of the elevation drive resulting
in a loss of telescope control. The observations could not be continued. Work is in progress to purchase new sensors and bring
them from Warsaw yet today, so that the telescope can be made
operational before the next experiment in this session.
Jodrell (Alastair Gunn at Fri Nov 19 12:35:10 MET 1999) Minor failures
Telescope servo failed at 03:57 UT and restored at 04:17 UT.
Brief servo failures also at 04:47 and 04:56 UT. Azimuth
motor failure at 08:26 UT, restored by 09:05 UT. No other
known problems.
Cambridge (Alastair Gunn at Fri Nov 19 12:35:46 MET 1999) Minor failures
Telescope control failure at 08:26 UT, restored by 09:05 UT. No other
known problems.
Effelsberg (A. Kraus at Fri Nov 19 12:36:02 MET 1999) Failure
A significant number of scans had to be skipped due to snowfall.
Observations were only possible between UT2200-0030 and UT0600-0630.
Westerbork (Tony Foley at Mon Nov 22 09:00:16 MET 1999) Success
No known problems. 13 telescopes in the tied array.
Onsala (A. Polatidis at Mon Nov 22 10:16:01 MET 1999) Success
Noto (C.Trigilio at Thu Nov 25 10:52:35 MET 1999) Success
Only 4 minuts lost because of power fail.
Calibration (Jean\-Francois Desmurs at Wed Dec 15 13:13:09 MET 1999) Minor failures
