AUST37

Hb:

  wind stows early in experiment, scan missed. Ross didn't record which scans were missed so I will have to manually go through the log at the end

Ke:

  Tsys bands 09, 11, 12 been a bit high 160-190 all experiment, and this has been happening with band 09 continuously in previous experiments too

Yg:

  problem with DBBC: scans missed, again Ross didn't note which ones
  Tsys band 11 consistently a bit low ~50 (I don't know if this is an issue) I don't know if this has been happening in previous experiments
  E-remote crashed for no reason but the field system kept running so no scans missed due to this (06:30 UT)

AUST38

Experiment started OK 00:00, all modules blank: Hb - HOB+0118/16000, Ke: HOB+1008/16000, Yg: HOB+0118/32000 And yes, that's correct, we have two different modules with identical VSNs: HOB+0118/16000 in Hb and HOB+0118/32000 in Yg. Both are used for AUST38 and AUST39.

Hb: strong spikes in ch 14,15)

Ke: S band, esp. ch11, 12, 15 – strange autocorr bandpass, extremely high Tsys (150-185K). RFI? Bad calibration?

Yg: DIMino program fails sporadically (scans 221-0101 - 0108 are lost); S band Tsys in ch 12, 13, 14 is too high (105-120K)

All: autocorr bandpass in ch.14 looks “steep” in all three antennas.

The Katherine delay difference has been drifting between .300 and .315 us

tsys on SBand at Katherine has also been very high at times throughout my shift

———————————————————————————————————————- AUST39

The disk positions are recorded on the printout (fairly early in the experiment) as too many scans were missed and there was no connection to Ke and Yg to figure out the start diks pos of the experiment End person (Warren) will have to look through the logs just for the first couple of scans to see which ones were actually recorded.

Hb:

  mk5 returned errors stating the that mk5 can't record while data transfers (for some reason this did not set off the alarm like it did at Ke)
  these errors were returned during the 1st couple of scans so I don't know if they're any good
  log reported that recording stopped mid scan 222-0016a (at UT00:16:42) and then reported that the next scan was 0013 (???)
  this ridiculous notion of re-recording a previous scan I think is what caused the field system to crash, missing all scans after this until 0036: e-remote doesn't work well as a time machine evidently
  schedule resumed at scan 0036 (disk pos: 5382.679)
  All S band tsys values too high for entire experiment

Ke:

  Alarms went off right at the beginning of the experiment saying things like (mk5-900): “can't record while data transfers”, “not while other activity”
  This went on until the field system had a fit and Jamie had to restart - again, I have no idea how usable any of these scans are
  first recorded scan after FS fit was 222-0041 (disk pos: 5843.831)
  Tsys values in bands 09-12 always too high (band 09 approximately 180K)

Yg:

  no connection throughout the start of the experiment but presumably, similar errors arose
  first scan after finally re-connecting was 222-0044 (diskpos: 5996.523)
  Tsys values in band 11 consistently 50K

Schedule errors day 222 22:32:31 and 22:33:27, requests to Mk5 recorder ( for scan_check perhaps?) while recording. Recording continued despite error messages.

——————————————————————————————————————– AUST41+42 Ke: Module USN+0224 8000 GB was loaded in Bank B but key not turned on! Martin attempting to get there, but probably expect late start…. Recording finally started to USN+0225 at 00:39 after modules sorted. Recorded data is -179 GB short of scheduled, due to late start. ATTENTION! Looks like module in bank B USN+0224 has bad soft VSN (name too long warning) will need to sort out when there is a substantial gap in scans. Aust42 commenced on bank B module USN+0224, as above. Hb: Recording to HOB+0041 starting at zero GB. Module changed in A to HOB+0023 6 TB ready for aust42 by Warren on Saturday. Hb automatically changed to bank A for start of scan 229-0530. Yg: Antenna stuck. Not in windstow, elevation brakes wont release. Dave local at yg went out to reset power in pedestal. Still no joy. Move to Current Issues! Elevation brakes will not release. fs, halt schedule. Need to switch power off in pedestal, open cabinet and switch to maintenance mode. Switch power back on, but this time to hand box control. Should be able to drive by hand. Switch power back over to remote mode. HMI interface should now drive telescope might need to “Reboot Central” in HMI. fs, antenna=open, antenna=operate, resume schedule. Good luck with all of that…. Recorded data is -404 GB short of scheduled, due to late start.

After start channels 11, 12 looked suspect in autocorrelation. clock jumped at 19:00. halted schedule and reconfigured dbbc at 19:03. fs crashed also. one missed scan 240-1902a. next good scan 240-1916. (missed scan record stop means -20 GB approx.) clock delay drifted from -0.29 us to -0.4 us around 240/20:30 and has stabilised see ke_ddiff.txt plot missed scans 240-2312 and 240-2328 due to dbbc reconfig. clock delay stable since 240-2330 (as of 240-0315) At UT13:40 day 241, the delay difference at Katherine started to drift quite badly, had to run fmset at 13.53UT (Imogen) For some reason, gnuplot will not plot values of ke_ddif.txt past ~11:00UT - not sure why (Imogen). At 14:29UT, restarted DBBC as clock drift was still occurring, ran fmset to resync dbbc and mark5. Delay seems to be stable as of 14:42UT, however cannot plot the values as they do not seem to be reaching the ke_ddif.txt file. yg: recording to USN-0019 start 0 GB spurious wind stow 240/21:22, antenna will not release elevation brake.

Ho This is a Lunar Lander observation. No schedules on IVS server by the beginning of the observation, experiment started late. First scan: 250-1742 to source 0308-611 @ 280.17:42:46.00 Receiver 20K stage is hotter than 40K LO unlocked at: 2014.280.21:14:28.44?ERROR ch -348 Receiver LO is unlocked 2014.280.21:14:49.51?ERROR ch -348 Receiver LO is unlocked 2014.280.21:15:10.59?ERROR ch -348 Receiver LO is unlocked 2014.280.21:29:19.43?ERROR ch -348 Receiver LO is unlocked Tried to repair LO unlocked by moving the antenna manually. Missed scans from 22:31:31 to 22:32:55 LO unlocked 281-02:24UT - Brett fixed by moving it a bit 281-02:32UT Temperatures were rising rapidly (along with vacuum pressure) so the schedule was halted so Brett can fix it. Scans after 281-0229 missed. 0337 first scan back. 2014.281.09:00:28.49#rxp#Receiver focus X : -255.5mm ; Y : 250.8mm ; Z : 18.6mm – Y position is a bit off (should be: 248mm); He supply pressure fell from 307psi to 302psi in 4 hours
