Experiment Feedback

Onsala (Michael Lindqvist at Wed Jun 3 20:32:35 2009) Success :

Apart from RFI. No known problems.

Medicina (Andrea Orlati at Wed Jun 3 21:04:33 2009) Minor failures : LATE

Schedule launch was 90 minutes late due to a block in the telescope driving computer.

Shanghai (Bo Xia at Wed Jun 3 21:45:31 2009) Minor failures :

From UT 10:30 to UT 10:46(No0001-No0003),the connection of the mk5 device and the clock pc is time-out with the network preoblem, so we cannot get the useful date. Form UT 10:47 to UT 10:59(No0004-No0006),the scan_check is failure,so we change to another diskpack. Two bad scan_check with 44 and 76 .

Urumqi (Wenjun Yang at Wed Jun 3 23:19:32 2009) Minor failures : HIGH

It is rainy and a little snow. From UT16:38 to 16:58, about three scans were lost because of the diskpack failure, quited mark5A system at UT16:38 and restarted recording at UT16:58. And there is warning message "Mark5A Warning:Recording throttled(can' keep up)" in Mark5A machine, no other error message. we will put Mark5A log file on to vlbeer's ftp server later.
