Torun (K.Borkowski at Mon Sep 20 10:03:58 METDST 1999) Success

10 minutes lost (3:29 - 3:38 on the first day, 259) due to unwrapping of the antenna cables around the azimuth axis.

Jodrell (Alastair Gunn at Mon Sep 20 11:09:11 METDST 1999) Minor failures

Prior to this experiment telescope control system had failed so all source changes were being done manually. Data may be affected in some scans. Control established at about 09:40 UT. Azimuth servo fault occurred and data lost between 12:48 UT and 13:00 UT. No other known problems.

Noto (C.Trigilio at Tue Sep 21 12:33:46 METDST 1999) Minor failures

No problem till 16:52 UT (day 260). A serious problem at the recorder (capstain motor) caused the interruption of the observations: lost the last 24 scans.

Westerbork (Tony Foley at Tue Sep 21 13:57:34 METDST 1999) Minor failures

Most of the time had 12 telescopes in the array. Data lost from 07:44 to 08:04UT with problems in the tied array
