Experiment Feedback

Noto (L. Nicotra at Mon Oct 20 01:05:02 2014) Success:

No known problems

Metsahovi (Minttu Uunila at Mon Oct 20 04:30:51 2014) Minor failures: TSYS

LCP works fine, RCP doesn't have enough noise (only 1.6K) -> Does not work properly and results in non-reliable Tsys values.

Onsala (Jun Yang at Mon Oct 20 06:49:34 2014) Success:

It was cloudy and quite humid. Once rain started, Tsys increased significantly. The weather was certainly not good for the 43 GHz observations. No other known problems.

Metsahovi (Minttu Uunila at Mon Oct 20 11:54:36 2014) Minor failures:

Weather: no rain but it was really humid and cloudy.

KVN_Tamna (Taehyun at Mon Oct 20 15:58:38 2014) Failure: ANT

Antenna Hexapod problem was occurred.

KVN_Yonsei (Taehyun at Mon Oct 20 16:02:14 2014) Minor failures: WIND HIGH

Rain & High Tsys from UT 15:30

KVN_Ulsan (Taehyun at Mon Oct 20 16:03:12 2014) Success: HIGH

Yebes (Daniel Sastre Walter at Mon Oct 20 20:58:51 2014) Success:

No known problems

Effelsberg (Uwe Bach at Tue Oct 21 08:54:36 2014) Success:

No known problems, but no fringes and the maser was not seen in the NME. Further investigations on the receiver will be done in the gaps between C-band VLBI in the following days. Weather was quite nice, only between 16 UT and 21 UT there was stronger wind with short a rain shower around 20 UT.
