Handover notes
Please use this page to write up any notes on anything that needs to be passed on to the next observer or should go into the end of experiment message.
Notes should be placed below the horizontal line as a new blog entry.
Continuing problems should be copied to the Current Issues page.
**Template for Handover notes:**
Be sure to add any specific notes about the experiment if required, for example “Special back end configuration for x reason”. Put as much detail as you can - the more the better.
====== Experiment Name ====== **Hobart 12m** Disk VSN: abc-123 | Data volume at beginning: 2.34 GB * 1300UT a comment from me (user) **Katherine 12m** Disk VSN: | Data volume at beginning: GB * **Yarragadee 12m** Disk VSN: | Data volume at beginning: GB * 1300UT Experiment started okay (JMc).
Format for entering a comment It is important to stick to this formula - there is a good reason we need this information, so please include it!
Time stamp in UT * Comment * (Your Name)
For Example:
20:00UT: Wind stows, Missed scans 012-3456 to 012-3457 (Jim)
20:50UT: Mark5 lost connection, had to restart Mark5 and reconfigure DBBC, called Jamie on call to fix, missed scans 012-3456 to 012-4567 (Jim)
Again - as much detail as you can. It is important to remember that these notes will be sent to the correlator, so please make sure they make sense to others.

- 17:00 UT - Experiment auto-started OK (JS)
- 23:00 UT - Channels 6,7 and 9 (from 0) looking bad. From ongoing DBBC issue? Tsys looks very bad.
- 00:13 UT - Reconfigured DBBC. Autocor and most tsys now look good. S band still poor. No missed scans. (Dave)
- 05:30 UT - Network connection flaky
- 06:30 UT - I rang the station and the guy rebooted the router and now the internet is fine (Ellen)

Hobart 12m:
Disk VSN: HOB+0127
Data volume at beginning: 7864 GB
Auto-started ok.
04:55 UT: Disk_pos 45 GB behind schedule. Recording is starting 3 seconds late, will be monitored for now (Ross).
07:15 UT: Disk_pos 50 GB behind schedule. Recording is starting 1-2 seconds late, looks stable (Ross).
12:05 UT - Disk_pos 70 GB short. mk5=net2vbs? Reading active on scan and inactive off scan. (vk)
16:44 UT - disk_pos 94 GB short (vk)
Katherine 12m:
Disk VSN: HOB+0129
Data volume at beginning: 7861 GB
Auto-started ok.
2015.039.08:39:31.04?ERROR st -27 Computer ACU time difference exceeded 0.25 seconds, problem corrected itself after scan started (Ross).
Yarragadee 12m:
Disk VSN: HOB+0123
Data volume at beginning:6663 GB
Auto-started ok.
07:20 UT: Disk_pos 30 GB behind schedule half-way through experiment, scans starting only 1 second late, will be monitored for now (Ross).
12:02 UT - Disk_pos ~50 GB short (vk)
12:16 UT - Channel 13 on autocorrelation spectra seems to have a discontinuity - almost. Is it RFI? The distortion in the spectrum is like a step, but has the band edges at the base of the plot. Notified on-call person –> Imogen.
16:34 UT - disk_pos 55 GB short (vk)
Anomaly with Channel 13 autocorrelation spectra has vanished.

Ops2 froze and crashed - had to restart, also internet seemed to be down for about half an hour All schedules started late. (Imogen)

21:56UT - Yarragadee eRemoteCtrl has completely lost connection; monitoring telescope via VNC to PCFS. (Imogen) 38/07:15UT - Antenna reported stuck. Resetting the antenna system in the HMI interface fixed it. 038-0715 partially missed. (Dave)

Hb USN-0072 0GB (6TB)
- 18:00 UT - Experiment started OK
- Around 05:50 restarted rfpic by mistake (with Yg) (Liza)
Ke USN-0012 0GB (4TB)
- 18:00 UT - Experiment started at around 18:03 UT due to antenna checking procedure for a1501ke. Around 3 minutes lost on scan 035-1800a. First full scan is on 035-1811.
- 21:54 UT - disk_pos ~10 GB short. This seems to be consistent with having missed the first scan after all.
Yg OAN+0006 0GB (4TB)
- 18:00 UT - Experiment started OK. sband tsys troublesome as usual.
- Scan 036-0535b may be bad due to antenna stuck at the azimuth limit (Liza)
- around 05:50 UT - restarted rfpic twice (once by mistake) (Liza)
- 08:44UT: scan 0119+115 antenna waiting at limit (Lucia)
- 12:05UT: The log monitor completely froze (this was when the last line was displayed). It didn't register an entry for almost an hour before I notice because it didn't set any alarms off. It wouldn't except any commands and I couldn't even close it. So I just open another instance at 13:02UT and dragged the other one off to the side… (Ellen)

Hobart 26m
recording to module HOB+0035, starting at 0GB
started ok
04:50UT: Connection lost with Hobart26, PC rebooted amongst other things, restarted monitoring at 05:33UT. Some scans in this time lost due to field system reboot (Ross).
