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.

Ke (11,467 GB on HOB+0125)
- Experiment started OK
- UT 04:17 Schedule halted to insert new module into mk5 bankB
- UT 04:34 Schedule restarted. Expecting to miss scans between 260-0417a and 260-0431a. Expected disk deficiency is ~70 GB.

Hb (Recording to HOB+0127) at 8,377 GB
- UT 01:15 Schedule halted for system checks at scan 260-0115b. ~10 TB on disk
- UT 01:48 System checks over. Expected first scan to be 260-0153b at UT 01:53. Disk deficiency of 160 GB.
Ke Recording to HOB+0125 at 9,171 GB
- UT 23:25 schedule halted due to FS crash, 10081 GB recorded. Restarted at UT 23:33.
- UT 00:57 Scans from last hour are lost due to FS crash again.
- UT 01:16 Restarted OK. Expecting scans from 259-2326 to 260-0116 to be missing. Disk deficiency of ~450 GB.
Yg Started on HOB+0119 at 0 GB but changed to HOB+1007 at UT 01:07
- UT 22:59 Swapped disk in bankA (R1 exp) - now mk5 does not record: mk5 connection failure.
- UT 23:03 - schedule halted. 499 GB recorded so far. Scan is 259-2301a.
- Discovered that the pointers on the 32 TB disk have become confounded as prior to UT 23:03, diskpos is ~1TB
- UT 23:40 Schedule restarted
- UT 23:46 Expect first valid scan to be 259-2343. However, again, mk5 connection failure.
- UT 01:07 recording this experiment to HOB+1007 now
- UT 01:08 Expecting first scan to be 260-0108. Looks good now.

Hb:
- Missed scan 258-1702a due to SpaceX changeover.
- Recording to USN-0201, +0 GB.
Ke:
- Missed scans up to and including 258-1901a due to VPN issue.
- Missed scans up to and including 258-1939 due to bad autocorrelation. First scan is 258-1944b.
- Recording to BKG-0052, +0 GB.
Yg:
- Missed scans up to and including 258-1837b due to VPN issue. First scan is 258-1841.
- Mark 5 at Yarragadee was powered off, however, this problem was not identified and rectified until 258-2037.
- Recording to USN-0179, +0 GB.
- Chris' comments
- Some (all?) scans have not been observed due to problems with the mk5. I appear to have made it run again. First scan is 258-2227a at 22:27:53.
- Recording to module TR-00014.
- Was anything recorded to USN-0179? Why are we not using it anymore?
- Scans 259-0005, 259-0007a, 259-0009a were missed for a module swap. 32 TB module HOB+0119 is now in bank B.
- Ross' comments
- USN-0179 has no useful data on it but was swapped out in case it was at fault.
