EL050C2015-06-02UweFailureWINDSorry, have to correct the previous entry. Because of strong wind the antenna was parked for most of the time. Started observations at 19:30 UT.
EL050D2015-06-03UweMinor failuresRECOProblem with parallel Flexbuff recordings kept the FS busy and therefore the we lost tracking between 15:35 and 15:55 UT.

EM115B2015-06-12UweSuccessNoneNone
EO0132015-06-18UweSuccessNoneEverything went fine using the new V105E firmware. High Tsys is BBC03 and BBC11 USB (1427 MHz), maybe because of RFI or spurious signals in the BBC itself.

EP096C2015-06-12UweMinor failuresWIND RFIAntenna was mostly stopped due to strong thunderstorms. Observed only between 15:55 to 16:15 UT and 16:50 to 18:30 UT.

ER043A2015-05-31UweSuccessNoneVery windy during the first hours until 16:30 UT.

GA0362015-06-01UweSuccessNoneNone
GB075C2015-05-30UweSuccessNoneLCP channel is faulty, Tsys is twice as high as in RCP and therewith less sensitive (higher SEFD). Weather was particular bad (strong rain) during the first two hours.
GL0392015-06-03UweFailureRECEMore or less a nearly complete failure. The antenna control system did not set the receiver to the correct LO frequency and Ef observed with an LO of 7900 MHz instead of 7700 MHz until 5:54 UT. Unfortunately the operator was not able to fix that during the night and it was solved only that late.
GN002B2015-06-14UweSuccessNoneStarted 17 minutes late at 14:47 UT, due to receiver set up problems.
GP053F2015-06-04USuccessNoneNone

N15C22015-06-04UweMinor failuresRECOAgain problems with parallel Flexbuff recordings which caused trouble with the main recordings as well.
