Experiment End date Friend Result Problem Text
EC0442014-06-17Jimmy CullenMinor failuresFSControl computer failed causing loss of data 20:40 - 21:14 UT and 03:30 - 03:55 UT
EC0482014-06-02Jimmy CullenFailureNoneMissed observation due to telescope control computer falling over
EG078B2014-06-06Jimmy CullenMinor failuresLATE FSProblems with the Mark5 recorder not accepting disk packs meant we missed the first hour of observations. Two control computer crashes at 04:27 UT and 05:51 UT meant observations were disrupted too.
EG078B2014-06-06Jimmy CullenMinor failuresNoneLow sensitivity eventually found to be an LO power level set in correctly. Polarisations swapped also.
EH0312014-06-04Jimmy CullenSuccessNoneDue to a bogie failure, the Lovell was replaced by the MkII for this observation. Otherwise no problems.
EL048A2014-06-03Jimmy CullenSuccessNoneNo known problems

EP087G2014-05-29Jimmy CullenSuccessNoneDue to a bogie failure, the Lovell was replaced by the MkII for this observation
EP087H2014-06-09Jimmy CullenMinor failuresLATEStarted observation a couple of minutes late. LO problems found and fixed during observation.
EP087H2014-06-09Jimmy CullenMinor failuresANTCal diode hardware failure detected and repaired. No cal diode data before 09:31UT
EP088E2014-06-02Jimmy CullenMinor failuresNoneObservation started at 09:12 UT when control of telescope was regained, however it was subsequently found that the LOs were incorrect and synthesizer control was lost. Telescope parked 11:00 - 12:00 UT while equipment was power cycled.

EP088F2014-06-10Jimmy CullenMinor failuresNonePotential LO problem at start of observation
ER035B2014-06-19Jimmy CullenFailureRECEUnknown problem, but we suspect a fault in the receiver

F14L22014-05-29Jimmy CullenMinor failuresRECO LATEMark5A recorder refused to acknowledge any disk packs. Eventually got it going, a little late. Jive5ab was started from the wrong directory (/opt/) and the first ftp fringetest failed because oper did not have permission to right the .m5a file there. Restarted jive5ab in home, but missed the second ftp fringetest because of a timing error in the schedule.

N14L22014-06-02Jimmy CullenMinor failuresRFIAfter the first ftp fringe test results were available we were aware that there was a problem. Eventually found an incorrect LO value had been set, which was corrected ~18:00 UT. Strong RFI noted in the band.
