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.

Hobart 12m:
Disk VSN:HOB+1009/16000
Data volume at beginning: 11682.37 GB
- pcfshb unresponsive, had to be rebooted (Ross)
- 17:00 UT - Experiment started OK (Ross)
- 19:38 UT - IVS halted for SpaceX support, missed scans 103-1947 through 103-1959b (Ross)
Katherine 12m:
Disk VSN:SHAO-020/2000
Data volume at beginning: 0.00 GB
- 17:00 UT - Experiment started OK (Ross)
- 06:00 UT - sband tsys high throughout obs (vk)
Yarragadee 12m:
Disk VSN:MPI-0153/2000
Data volume at beginning: 0.00 GB
- 17:00 UT - Experiment started OK (Ross)
- 17:20 UT - e-remote not working, killed all instances using pcfs and restarted (Ross)
- 21:09 UT - Power outage at Yarragadee, entire system rebooted. Missed scans 103-2106a through 103-2211a corresponding to a deficit of 51.1 GB. Time difference between Mark5 and field system high but stable at 0.5 seconds (Ross)
- 23:20 UT - Phonecall from Jim Lovell who's going to have a go at fixing the ACU time difference errors as well as the error from the System Monitor as a result of the power failure (vk)
- 23:35 UT - Reboot of Field System PC seems to have solved timing issues. Scans 103-2334 and later should be OK. Unsure if scans between 103-2106a and 103-2333b will be recoverable (Jim L)
