AOV012

Hobart 12m:

Disk VSN: HOB+0102, start 6819.09 GB

  • 1730UT Experiment started okay (JS)
  • 1945UT SystemClock1 errors. Attempting to diagnose (JS)
  • 1950UT Looks like the generator has died at hb, Brett is going out to refuel (JS)
    • Affected scans: 286-1941 to 286-2307a. ie first good scan was 286-2311
  • 2311UT Experiment restarted (Liz)

2016.287.03:28:26 Scan name = 287-0027 2016.287.03:28:26 ALARM: error m5 -900 already off

2016.287.03:28:26 WARNING: error m5 -906 mark5 return code 6: inconsistent or conflicting request 2016.287.03:28:26 Total data recorded = -7041.000 GB 2016.287.03:28:26 Scan name = 287-0032 2016.287.03:28:26 ALARM: error m5 -900 no scans

2016.287.03:28:26 WARNING: error m5 -906 mark5 return code 6: inconsistent or conflicting request

  • 11:40 UT Autocorrelations look a bit askew in sub-bands 7 and 9. I'll monitor them over the next few scans and configure the dbbc if they persist (Lucas)

Katherine 12m:

Disk VSN: HART+104, start 7040.11 GB

Disk VSN: HOB+0015, start 1533.39 GB

  • 1730UT Experiment started okay (JS)
  • 2117UT Katherine switched back to bank A (HOB+0015) since bank B was at capacity.

HOB+0015 will need to be shipped off for the r1761. So it's best to start recording to a third module as soon as we can, and then retrieve the data for this experiment from HOB+0015 later before shipping. Speak to the on-site person when they're in to switch out a module

  • 0030UT Katherine switched back to bank B (XAO-1013) for bank A (HOB+0015) to be able to be shipped etc for r1761. (Liz)
    • Missed scans 287-0027 and 287-0029 (Liz)
  • 0328UT alarm sounded ALARM: error m5 -900 already off, WARNING: error m5 -906 mark5 return code 6: inconsistent or conflicting request, ALARM: error m5 -900 no scans, and then fixed itself. On closer inspection, log monitor seems to be printing information about scans from the last 2 hours in quick succession over 0321-0331UT. All outputs before and after this bracket match the schedule file. Seems to be fine now, and eremote was unaffected so appears to be a strange log monitor artefact rather than anything wrong with the experiment. Will monitor for now. (Liz)
  • 0509UT Happened again. Alarm at 0457UT and 0503UT. Spoke to Jamie. Log file was reading from a tmp file which he thinks was probably the cause. Made new log file on /vlbobs/~ seems to be something was26 GB

2016.287.06:05:10 Scan name = 287-0605b interfering with the tmp file and log monitor was having to rewrite experiment history (Liz).

  • 11:40 UT Autocorrelations look a bit askew in sub-bands 1, 3 and 8. I'll monitor them over the next few scans and configure the dbbc if they persist (Lucas)

  • 1720UT No response from MK5 needs to be rebooted, can't get trhough to yg telephone!! (JS)
  • 1740UT reset mk5 via ip switch (JS)
  • 1752UT Onsource for 286-1752a (JS)
    • missed scans: 286-1730 to 286-1745
  • 2345UT For some time yg has had formatter to fs time difference 0.5s or greater as mk5=dot? response nearly 1 sec out. According to Jamie fix with fmset after this experiment end. (Liz)
