The observations went smoothly. There might have been a problem soon after the tape change. The FS was complaining about the head 2 positioning; this was fixed by re-entering the positioning by hand. A few seconds of the first forward pass on the second tape might have been lost.

Onsala (A. Polatidis at Sat Nov 21 11:44:03 MET 1998) Success

The problem with the recording head was fixed and we are observing again. No known problems.

Noto (C.Trigilio at Mon Nov 23 10:19:57 MET 1998) Success

seems OK

Westerbork (Tony Foley at Tue Nov 24 16:28:12 MET 1998) Minor failures

Possibly polarization wrong from 0800 to 0820UT. Many scans after 1130UT outside Hour Angle range. During a playback test tracks 26-32 gave high parity errors, but our decoder works badly at 8Mbits/s.

Jodrell (Alastair Gunn at Wed Nov 25 07:47:06 MET 1998) Minor failures

FS crash at start of scedule, okay by 08:07 UT. Tape didnt stop at 08:27 UT, error by PI in timing. Tape failed to start at 13:01 reversal, started manually at 13:05. Incorrect antenna.ctl file used, should be Mk2.

Calibration (Jean\-Francois Desmurs at Fri Dec 11 16:14:14 MET 1998) Success
