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.

Hb HOB+0102 (bank A) Data recorded = 5365.691 GB (VK)
08:05UT: Antenna wind stowed. Antenna got stuck coming out of wind stow, had to reset drives, but immediately had to go back into wind stow. Stowed antenna, halted schedule, to wait for wind to subside enough to safely resume schedule. (Imogen)
08:15UT: Abnormal auto-correlation reading in channel 11. Corrected itself when schedule restarted after wind stow.(Imogen)
08:22UT: Attempted to restart schedule, but antenna immediately went back into wind stow. (Imogen)
08:26UT: Attempted to restart schedule, but again antenna did not come out of wind stow. Stowed antenna, halted schedule and rebooted drives. Resumed schedule and restarted drives. Antenna still went back to wind stow. Wind speed average 35kph and decreasing. (Imogen)
08:32UT: Wind speed has sufficiently slowed, but antenna did not move to source. Stowed antenna, terminated field system. Began procedure to restart field system, however at that time, wind reached over 60kph and stayed there, so schedule was not resumed immediately. (Imogen)
09:08UT: After wind subsided, drives were reset again, schedule was successfully resume. (Imogen)
Missed scans 285-0802 to 285-0906.
09:30UT: Antenna entered wind stow again. (Imogen)
09:57UT: Mark5 was recording when antenna was stowed, therefore may have some useless data before 09:57UT. Mark5 was stopped, schedule restarted. However, drives were still indicating as stuck, even though there was no wind stow indicated in drive control window. Halted schedule, turned off antenna with antenna=off, restarted antenna with antenna=open, antenna=operate. Restarted schedule successfully at 10:05UT. (Imogen)
Missed scans 285-0931b to 285-1006. (Imogen)
10:23UT: Wind stow activated. (Imogen)
10:32UT: antenna did not recorver from wind stow, had to turn antenna off and on again. (Imogen)
