Medicina (Andrea Orlati at Mon Feb 21 10:19:43 2005) Success :
It snowed starting from 22:30 UT. No other known problems
Effelsberg (A. Kraus at Mon Feb 21 12:51:40 2005) Minor failures : WIND
Stopped due to snowfall: UT1430-1530, UT1700-1945.
Robledo (Cristina Garcia Miro at Tue Feb 22 17:44:31 2005) Minor failures : RECO TSYS PCAL
During pre-cals formatter was failing the sync test, command form4=/syn was sent at 13:26UT, additionally fmset was run to synchronized formatter with station time.
Small delays in schedule execution (and too short scans) produced tape position errors at beginning of reverse passes of about 1000 feet.
Phase cal tones amplitude was readjusted from 22:50 to 23:15UT.
X-RCP noise diode was manually configured and fired to provide tsys measurements at beginning of most forward and reverse passes (until 21:18UT).

Effelsberg (A. Kraus at Fri Mar 11 09:11:32 2005) Minor failures : HIGH
In addition, Tsys is higher, sensitivity lower - probably due to snow in the dish.
