Torun (K.Borkowski at Wed Nov 18 09:28:09 MET 1998) Success

No known problems.

Onsala (John Conway at Wed Nov 18 12:43:14 MET 1998) Failure

We did not observe due to the failure of our write head positioning immediately before the expt. The problem appears to be in the inchworm itself and not the drive electronics. We are investigating to see what we have to do to get back on the air.

Medicina (Dallacasa D. at Fri Nov 20 07:51:44 MET 1998) Success

No apparent problems reported during the observation.

Westerbork (Tony Foley at Fri Nov 20 12:11:51 MET 1998) Minor failures

No valid weather information. Please check polarization! We were using a new system to check it.

Effelsberg (dgraham at Fri Nov 20 14:49:13 MET 1998) Success

seems OK

Urumqi (Liu Xiang at Mon Nov 23 05:46:00 MET 1998) Minor failures

The system seems okay, but in UT23:25--UT 01:24 the time was faster two seconds than correct time. The clock offset was 1.5us. It was clear.

Noto (C.Trigilio at Mon Nov 23 10:15:07 MET 1998) Minor failures

Clear sky. BBC03 not working from 22:00 to 23:00. Subreflector not in correct position -> gain expected lower of about 10%

Jodrell (Alastair Gunn at Wed Nov 25 07:45:18 MET 1998) Success

Incorrect antenna.ctl file used, should be Mk2.

Cambridge (Alastair Gunn at Wed Nov 25 08:17:49 MET 1998) Minor failures

Missed first two passes due to wrong FS/formatter day/time. Fire alarm at 03:04, data lost until 03:12 UT.

Shanghai (Huang Xinyong at Fri Nov 27 06:49:38 MET 1998) Success

No knowed problems. Tape was sent out from Shanghai to Bonn on 26, nov..

Calibration (Jean\-Francois Desmurs at Fri Dec 11 16:12:25 MET 1998) Success
