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.

- All turned out to be due to FS problems. All corrected itself after one more reboot of pcfske.
- Experiment started OK (Liza)

Data volume at beginning: 0
- 08:40 UT - I noticed that the AneMonitor wasn't even running when I went to check the wind, I don't know whether it crashed or whether no one had been checking. (Ellen)

Module: CURT+102 start pos 1842.4 GB (this was the only module in the mk5 again!!)
- 1732UT experiment started OK (JS)
- 00:00 UT - All telescopes 1 second out. Had to reboot the FS as nothing else worked (under the guidance of Jim). Missed scans 182-0010 and 182-0019a. Schedule resumed for scan 182-0021 but the mk5 was still 1 sec out (we forgot to sync). (Ellen)
- 00:31 UT - Schedule resumed properly with no time differences. First good scan 182-0034b. (Ellen)
- 00:45 UT - Mk5 decided to correct its own time and so with our correction was out by 1 sec. We then undid our correction. Affected scans 182-0044 and 182-0052. (Ellen)
- 05:01 UT - Noticed error in Write status for antenna. I restarted the drive and that fixed it. I'm not sure how long it had been there for as no alarms went off. Scan 182-0451 affected. (Ellen)
- 07:42 UT - Windstowed until 07:47. Scan affected: 182-0739. (Ellen)
- 08:01 UT - Windstowed until 08:08. Scan affected: 182-0759b. (Ellen)

- 01:02 UT - Mk5 decided to correct its own time and so with our correction was out by 1 sec. We then undid our correction. Affected scan 182-0102. (Ellen)
- 15:39 UT - Antenna got stuck, reconnected 15:50UT. Scand lost: 182-1538, 1546. Later we learned tha the electreicity gone of at 15:39 (Liza)
- 16:04 UT - FS hunged up, killed, restarted. Resumed recordin at 16:16, scan 182-1604 is lost. Network is slow? (Liza)
- 16:28 UT - FS hunged again and after restoration again, restarted pcfshb, then restarted FS which hunged up again. Restarted at 16:46 UT (Liza)

- S-band tsys high. (Dave)

Fringe check done with all 3 telescopes using source 0537-441. No fringes detected in any baselines and plots were just flat lines. Trying again with the same source and all the plots had data in them the second time. (Ellen)
- Baseline hb-ke: no fringes detected

Really weird looking Auto-correlation, possibly rendering wrong?
UT 1810 Autocorrelation not updating elected to reset fs. No change (JS)
UT 1818 Tried the “file too large wrong length written” thing because the watchdog went off. FIXED Auto-corr spectum! (JS)
UT 1822 Scans 177-1754 to 177-1811a possibly bad because of auto-spec issues (JS)

- 01:00 UT - pcfshb out of disk space. No log file written between 00:49 and 01:17. Observations should not have been disturbed though. (Lucia)
- Model swap: small modules. Mk5hb hunged up after the swap and had to be restarted. Scans 0205-0226a lost. Scans 0228-0229a got recorded on the small module USN-0182/2000 meant for R4693hb. Run fmset, expect small clock jump. (Liza).
