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.

Yg
Module: HOB+1007, +0GB
- Good pointing fit. (Dave)
- eRc refusing to connect. Using backup FS interface. (Dave)
- Tsys still looking good! AGC in IFC is close to saturated though at ~62. (Dave)
- 22:05 UT: eRemote Control restarted and working fine (Ross).
AuScope "Bedroom"
There is a very bad burning smell in the room. Liza noticed it at 5pm on Friday and Security was called but they didn't come. When I took over for my shift at 11pm, Liza said it smelt worse (after leaving the window open for her entire shift) and she phoned Security again. This time they said they'd come and have a look but didn't (or the sight of me asleep on the floor in the main room terrified them and they just ran away). The only solution we came up with was to close both doors.
Liza and I dragged the mattress out in front of ops2 and an I just slept there (I think it may actually be more comfortable than sleeping on the frame…)
If you concerned about this during your shift, maybe you will have better luck convincing someone to come take a look…
Good luck, Ellen
