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.

07:23UT - DBBC strangely restarted itself. Logged back in, reconfigured and the problem is fixed for now (Imogen)
07:50UT - It seems the GPIB has lost its connection with the mark 5 and field system. Tried to restart mark 5 and field system, didn't work. Then tried to restart the GPIB but the PDU webpage was not available for some unknown reason. The antenna also got stuck. The internet connection wasn't working effectively and I couldn't log in to timeke to rectify the problem by restarting the drives. It would not stow through field system command initially. Not even webcams are working so can't tell if the antenna has actually stowed. (Imogen)
08:17UT - still trying to fix mark 5/DBBC/GPIB problem but nothing is responding due to poor internet connection. There was a power glitch and UPS connected to the DBBC and Mark 5 has died. Martin is taking the DBBC, GPIB counters and Mark 5 off the UPS and connecting them to the mains, so if there is another power glitch, the DBBC, Mark 5 and GPIB counters will still be able to be restarted remotely. (Imogen)
09:14 - Martin restarted UPS's. Mark 5 clock is still not synced, trying to fix the problem (Imogen)
09:35UT - ALARM: error st -999 systemclock connection error. Fixed with commands “antenna=operate” and “antenna=open”. Mark5 was stuck with its record mode on (FHG_on), so ended the process and did another fmset. This fixed the problem. (Imogen)
09:55UT - DBBC lost connection again - it seemed to restart, possibly another power glitch? halted schedule while DBBC reconfigured. Restarted schedule 09:59UT. (Imogen)
10:10UT - Alarm kept sounding for Mark5 apparently not being in sync, halted schedule, ran fmset, restarted schedule (Imogen)
22:06UT - Volume of data recorded is 3.835 TB, which is about 900 GB behind schedule (Chris)

- Observations started as planned, but the mk5 was not yet synced. The first good scan starts at 00:07:20 (0826-373) (Chris)
- 00:53UT: Observations are about 8 GB behind predicted schedule amount. This is not quite the same as how much was missed at the start, but only within 5 GB. (Chris)

- 16:30 UT Looks like DBBC PC was off, did a reset (halt issued at 16:34) and resumed at 1642 UT (JS)
- 16:48 UT FS dead (no response with clkoff command) FS terminated (JS)
- 16:58 UT schedule resumed (default command) (JS)
