Experiment Feedback

Torun (K.Borkowski at Fri Jun 5 11:57:54 METDST 1998) Minor failures

No apparent problems until 8:32 UT. At this moment the recorder failed to move the tape altogether (near the low tape sensor). We cannot dismout the tape; it looks as we have a serious problem.

Medicina (Morsiani at Fri Jun 5 13:42:38 METDST 1998) Success

It looks that log file is missing.

Onsala (John Conway at Fri Jun 5 14:17:20 METDST 1998) Failure

Did not observe this experiment, had a complete failure of the MAT card used for head positioning during previous expt. This card had now (Friday midday) been replace and we are observing again. Sorry Franco this expt seems jinxed somehow.

Noto (C.Trigilio at Mon Jun 8 17:38:25 METDST 1998) Success

Jodrell (Alastair Gunn at Tue Jun 9 03:02:41 METDST 1998) Success

High signal in VC4, doesnt look like RFI. No other known problems.

Cambridge (Alastair Gunn at Tue Jun 9 03:03:20 METDST 1998) Minor failures

Vacuum lost at 00:58 UT, tape started again at 12R scan at 01:10 UT. Lost again at 02:00 UT, started at 17F at 02:06 UT. Receiver cryostat failure during the previous night - expect low signal. Telescope taken offline at 09:00 UT to fix receiver.
