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.

- recording on USN-0130 3% used by 3 previous MEX tracks
- clear
- source set (?) at 2015.008.07:06 (antenna “waiting at limit” after), schedule halted, antenna returned to stow

- el offset is still large, run pointing procedure on the telescope before the start of the tracking – telescope got stuck, late start of the valid data due to that

Experiment was started late.
Hobart 12m:
Disk VSN: HOB+0112
Data volume at beginning:0GB
05:20UT - Hobart started schedule (Imogen) (1260 GB missed)
14:26UT - The hard drive of the pcfs machine for Hb became full, and the log was not writing. A few minutes (until 14:34) of log was missed. Deleted some files to keep the log writing (emailed Jamie about this) (Chris)
Katherine 12m:
Disk VSN: HOB+0104
Data volume at beginning:0GB
- 05:14UT - Katherine started schedule. 1243 GB missed. (Imogen)
- 09:40UT - System reported antenna was stuck. Rebooting antenna firmware a couple of times and re-establishing connection to fs fixed it. Scans 354-0940–354-0949 missed. (DH)
Yarragadee 12m:
Disk VSN:HOB+0083
Data volume at beginning: 8.04TB
05:27UT - Yarragadee started schedule. 1207 GB missed (Imogen)

- Data volume at beginning: 13.308 TB
Katherine 12m:
- Disk VSN: HOB+0075/8000/1024
- Data volume at beginning: ???
13:20UT - DBBC appears to be on but not responding, cannot be power cycled. Katherine will miss start of experiment (at least) until Martin can visit site (Ross).
19:10UT - Appears internet connection to Katherine may be down (Ross).
20:25UT - Internet switches power cycled by Martin and dbbc plugged directly into main ethernet router. Mark5 not logged in, re-logged in to by Martin (Ross).
20:54UT - Katherine finally has joined the experiment with scan 352-2052, -230 GB (Ross).
23:20UT - Can't connect to specke, timeke, ipske, kvmke, pdu2ke even though lights appear to be on. pcfske, mk5ke, mk5-2ke, pdu1ke and dbbc computers are fine. Martin has gone to fix (Ellen)
23:44UT - Everything except specke restored. Martin just re-powered the d-link, but did say that he could hardly ever get specke to work. (Ellen)
01:40UT - DBBC just shut down out of no where. I opened the VNC session and the program wasn't running. Schedule halted 01:43UT. Bad scan: 353-0140a. Schedule resumed 01:45UT, no scans missed. (Ellen)
KATHERINE HAD A WIND STOW :O 05:37UT - the antenna got stuck first, and then at 05:39UT after I tried to reset it, it got caught in wind stow. Schedule resumed 05:49UT. Missed scans 353-0533b and 0548. Also, just following the procedure in the current issues didn't work, I had to manually turn drives off and on again before “antenna=operate” worked. (Ellen) … corresponds to ~40 GB shortage in data (vk)
