Hartebeesthoek (Jonathan Quick at Thu Oct 20 21:41:37 2005) Minor failures : RECE ANT

Started late due to secondary reflector controller failure. RCP receiver went unstable some 2.5 hours into the esperiment, LCP seems OK.

Shanghai (Tao An at Thu Oct 20 21:42:48 2005) Success :

before experiment clock offset = utc(seshan25)-utc(gps)=78.83us. after experiment clock offset = utc(seshan25)-utc(gps)=78.92us. the frequency accuracy is 0.74x10(-12). No known problems.

Shanghai (Tao An at Thu Oct 20 23:03:17 2005) Minor failures : HIGH

We have found that the cryogenic system stopped working before the experiment. As a result, the system temperature increased by a factor of 2. We are examining the cause of the problem.

No known problems.

Onsala (Michael Lindqvist at Fri Oct 21 06:44:55 2005) Minor failures :

Short antenna communication problem, around UT 18:40. Rather bad weather (some rain) and high wind speeds.

Formatter problems between UT1924-1935.

Wb used in phased array mode. no known problems

Jodrell_Bank (Alastair Gunn at Tue Nov 1 12:07:24 2005) Success :
