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.

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.

Disk VSN: HOB+0117/32000 | free space at beginning: 11502 GB, data volume begin 20498 GB (Warren) disk is 32000 G in total and experiment is around 6000G so should be fine .
- 17:30UT- Experiment started OK (Katie) - Although eremote control completely lost connection, but closing and opening it again fixed it.
- 21:20UT-ALARM: error fl -1 previous source in this schedule not reached before new source was commanded, then saw on eremote control instead on 'Antenna onsource' or tracking, it said antenna stuck. Also Drive status –> Not Ready. On timeke, it says that the E Stop has tripped. Called Mick, didn't reach him. Warren on the way though. (Katie)
- Antenna problem started at scan 163-2124 (Katie)
- Antenna fixed and next good recording aua046_ke_163-2259 at 22:59 (Warren)
- 09:00UT-eRemote control, keeps losing connection for a few seconds and then reconnects. (Katie)

Module currently in is too small, tonight's R1 is a double data rate experiment. Have contacted Mick, he is heading out to swap it for a 6TB disk now.

Module too small, called Michael at Yg and he is swapping over to a more suitable size.
Disk VSN: HOB-0022 (not showing VSN in FS) | Data volume at beginning: 0.705 GB
17:00UT - Experiment started OK (Tiege)
14:16UT - No PCFS activity for xx minutes. Check VNC session to see if Field System software is running Check Network connection. Error in VNC saying 'wrong length written, file probably too large'. Same problem as before, not enough space for logs, called Jamie and he made more space (Katie).

18:30UT Experiment started OK (Patrick)
06:00UT Warning: No PCFS activity for xx minutes. Check VNC session to see if Field System software is running Check Network connection. The disk on the PCFS machine was full so it couldn't write the logs. Called Warren and he made more space (Simin).

Hobart 26m
Disk VSN: HOB +0119/32000 | Data volume at beginning: 2050.764 GB
Received error “Problem connecting to metserver socket” for every scan (mas)
18:00 UT Experiment started OK (mas)
18:37:40 UT Log monitor started to report negative disk usage for some of the scans (mas)
19:53 UT Halt schedule to sync the Field System clock. Missed scans no0022 & no0023 (mas)
07:30 UT - Noticed autocorrelation spectra was not updating. Checked procedure file (compared to aua043) and noticed it was missing a bunch of procedures (including postob, which produces the spectra). Copied those procedures into the aua045ho.prc file, and reloaded it with proc=aua045ho. Now the spectra are showing up, and they look fine (Patrick)
11:34UT - windstowed: 11:34-11:56 (scans no00183-no00186) (Patrick)
16:55UT - S/X receiver cryo pressure jumped to above 6 microns Hg, and 70K stage started warming up. No point driving out to Mt. Pleasant to fix it, as experiment only has 1 hour to go. (Patrick)

18:00 UT Experiment started OK (mas)
18:00 UT Received “Warning: error tc -301 continuous cal not enabled for DBBC” for every scan (mas)
18:18:45 UT Log monitor started to report negative disk usage for some of the scans (mas)

07:00UT - Recieve an -103 pointing computer tracking errors are too large and qo -301 warning: onsource status is slewing! at the start of each scan. Telescope is late on source by a few seconds. (Patrick)
09:20UT - continuous cal error is safe to ignore according to Warren, so I have changed the Ke alarm_actions.txt to ignore it for this experiment. (Patrick)

18:15:30 UT Halt schedule and tried to sync the seconds decimal for Field System and computer (0.02 micro seconds difference with Mark5) but couldn't sync. Maserdelay and clkoff are OK. Missed scans no00005 & no00006 (mas)
07:00UT - Recieve an -103 pointing computer tracking errors are too large and qo -301 warning: onsource status is slewing! at the start of each scan. Telescope is late on source by a few seconds. (patrick)
12:43UT - Module MAT+0003 ran out of disk space. Called Yg, new module put in (HOB+0051). Schedule resumed at 12:50UT. Scan missed: no00194 (Patrick)

- Experiment started okay (Lucas).
- Had to quickly restart dimino on mk5ke. Wasn't sure it was running correctly as it didn't have the “./dim r1845ke” in ps -ef | grep -i dim even though DIMino -m0 was running (Lucas).

Disk VSN: IAA-0064/2000 | Data volume at beginning: 0.00 GB
- Very windy at Yaggy. Pointing check interrupted. First few scans missed.
- Note if comments.py doesn't pick up wind stows (or all wind stows) you can
- grep “Auto” r1845yg_erc.log | grep -C 1 “Restart”
- and it should get all instances of stows starting and ending (Lucas).
- First scan 155-1709 (Lucas).
- Stows so far:

18:30:00 UT Formatter to fs time offset was high. Rebooting mk5 and sync did not fix the issue. Had to wait for Warren to fix it. Scan missed from 151-1830b to 151-1859. Recording resumed from 151-1903. (Atifur)
19:35:36 UT No delay drift was noted but alarm sounded with error “Delay through DBBC has changed”. Schedule halted and DBBC reconfigured. Schedule resumed at 19:42:16. scan missed: 151-1934-151-1943b. (Atifur)
Halt and resume schedule several times. Tried to reconfigure and reboot the DBBC. Received continuous alarm “Alarm large difference between formatter and maserdelay. Check for stability of new offset”. Delaylive show linear drifting. Missed scans 152-0022a to 152-0027a, 152-0054 to 152-0105, 152-0123 to 152-0138b (mas)
