No problems, although not smoothly wound tapes may
result in a poorer playback. Weather predominantly fine (day sunny)
till tonight evening when an atmospheric storm passed nearby.
Noto (C.Trigilio at Mon May 29 10:26:53 METDST 2000) Success
Effelsberg (A. Kraus at Mon May 29 11:29:55 METDST 2000) Minor failures
At the beginning a wrong tape label was given. Since this was not
rejected by the system, during the first five scans a wrong tape speed
and footage was set. Only part of the data was recorded. Scans 3 and 5
were lost. This was corrected at UT 2235 (day 147). The failure of the
field system computer caused the loss of data from UT 1912-2015 and
UT2035-2100 (day 148).
Westerbork (Tony Foley at Tue May 30 10:31:30 METDST 2000) Minor failures
Used full array (14 telescopes). From 21:00 to 21:48 polarization
was swapped. Lost scans from 03:08 to 06:46 with DCB computer not
initializing, and again from 12:47 to 14:03. Had to reboot
Several scans from 14:05 to 16:29 out of hour angle range, so not
Westerbork (Tony Foley at Tue May 30 10:34:55 METDST 2000) Minor failures
A hacker was active in WSRT during this period.
There was no obvious interference in the online systems.
Jodrell_Bank (Alastair Gunn at Mon Jun 5 12:23:26 METDST 2000) Minor failures
Usual RFI at 1672 and 1685 MHz. Receiver performance looks very good
except for ringing around these RFI spikes. Running with IF filter
centred on 1658 MHz and 16 MHz bandwidth to keep interference out.
Problems with telescope control may have caused some scans to be lost.
