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.

General Notes At end of experiment couldn't see manual Yg weather data past 2016_08_25, spoke to Jamie who suggested an email to Jim, just processed logs without. To be followed up. (Liz)

- 17:30 UT - Delay difference is higher than normal, ~0.5 us, however it is sitting stable at this delay so I have left it be. (Tiege)
- 18:30 UT - Experiment started late, during first scan sync error developed, halted schedule, first valid scan is 252-1840. This also has fixed the larger delay. (Tiege)
- 23:10 UT - Delay difference falling off consistently though linearly. Rate has now begun to steepen over last few scans with alarm triggered (Ross).
- 23:40 UT - Delay difference following new linear fall off, but so steep it will exceed 1ms by end of experiment. dbbc restarted. Missed scans 252-2341b and 252-2348b (Ross).

- 14:21 UT - From 14:19:38 to 14:21:55 got “WARNING: error st -27 computer acu time difference exceeded 0.25 seconds, see value above.” As no major alarm sounded, recording continued throughout and seemed to rectify itself quickly, assumed non-critical and considered resolved.

- I messed up, and didn't start the telescopes at 1700UT. By the time I realised I was on, it was 2300UT. All telescopes running by 2320UT (JS)

General Comments
- All three antenna having the following error intermittently: “Antenna outside nominal tracking tolerance of 0.0045 degrees, current tolerance 0.0100.” Hb and Ke are windy, Yg not so much. Wiki states this is most likely due to the dish trying to compensate for the wind gusts. (AK)
- disk_pos is lagging on all stations by varying amounts. The amounts are logged in the checklists. (AK)

- Pre-observation setup: hb is stuck in /mk5/!mode? 0 : ext : 0x55555555 : 4 : 2 ; - I think there is something wrong with the proc file, Couldn't figure out the problem with Warren's help. (Bryn)
- Pre-observation setup: mk5=dot? returning syncerr_gt_3 constantly - have tried resetting ntpq on mk5, rebooting mk5, reconfig dbbc and running fmset several times, to no avail. (Bryn)
- 18:33 UT: Experiment started late - missed scan 245-1830 (Bryn)
- 18:35 UT: Getting WARNING: 0 : 0x00340003 : 1028 : interrupts error from mark-5b dim or dom, halting schedule to restart dim
- 18:50 UT: Rebooted mk5 computer. Resynced DBBC & mk5 with fmset. Still getting syncerr_gt_3 and interrupts errors (Bryn)
- 19:16 UT: Getting format problem errors from mk5, halting schedule until I can contact Jamie for fix (Bryn)
- 22:49 UT: Errors fixed by Jamie. Clock rate was set wrong on pcfs causing all of the above errors. First good scan is 245-2249 (Bryn)
