First 20 scan without tsys: Problem to the frequency 5280
(K. Borkowski at Tue Jun 17 06:51:33 2014) Minor failures: HIGH ANT
First scan observed with very high Tsys (the reason seems to have something to do with change of HF filters, but is somewhat misterious and will be further investigated). Since 1:44 UTC for about one hour the FS lost telescope control which in this case means that during this period the telescope tracked continuously only one source (K3-35).

The LO was wrongly set up for all the experiment.

Control computer failed causing loss of data 20:40 - 21:14 UT and
03:30 - 03:55 UT
(Jun Yang at Mon Jun 23 09:40:32 2014) Minor failures: ANT
The fuse associated with the Declination motor was blew again at night. The exact time was
at ~0:40 UT. After that, the antenna could only track the calibrator J1925+2106. The
observations stopped at 3:40 UT when the operator noticed the problem.
