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.

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.

- 1800UT Started OK, 40k at 400K :( pressure is dropping and temperatures rising keeping an eye out (JS)
- 1930UT Helium pressure is above 5 umHg, can't do anything until Warren gets to MtP (JS)
- 23:00 stopped for an hour to change cryo hose. Still a leak (Warren)
- 00:00 receiver cool but helium requires constant topping up Warren)
- 00:00 data down about 170 GB due to service hour (warren)
- 10.42 UT, Cryogenics He supply pressure is warming up now (250 psi). 70 K stage temperature around 125.9 K and pressure 7.1 micorns Hg. Have informed Warren about it, he said just need to wait till experiment finish (mas)

- 00:49UT - FS terminated due to operator error, restart delayed due to drive PC crash. Schedule resumed with first good data from 0103. (JMc)
- Missed scans 010-0049 and 010-0056 (JMc)
- 06:05UT - S/X receiver pressure rising, Warren is heading out to fix the He pressure which is also falling and will fix this also. However, he can't go out until after his lecture. Data from now until otherwise said will be subject to higher than nominal system temperatures. (Tiege)
- 09:30UT - Warren has fixed the S/X receiver pressure, will take a while for the 70K stage temperature to fall to nominal values, but it should be getting better from now. (Tiege)

- 14:29UT - Prior to experiment start, GPIB has given up the ghost. first with error “ib -524 gpib/232 converter timed out”, then after fs restart “ib -10 ibcon initialization failed, gpib devices inaccessible”. Rebooting pcfske to try and fix (Tiege)
- 15:00UT - Jamie thinks it is an issue with the UPS attached to the GPIB etc. Going to try and get someone on site in the morning. Manually entering counters for now. (Tiege)
- 15:10UT - I have sent a message to Mick letting him know what has happened, what the assumed problem is, and asked him to head out first chance he gets in the morning. (Tiege)
- 16:00 UT - Mick just called, he has gone out and switched the UPS back on, everything working now, though the storms are violent at the site (Tiege)
- 17:00 UT - Experiment started OK (Tiege)

1900UT Experiment started OK (mas)
- 00:00:39 - Module full, phoned Yarragadee to swap in a fresh module. Scheduled resumed on HOB+1009 at 00:04:59 (JMc)
- 05:16 Mark5B crashed. (Warren)
- 05:40 Called conrtrol room to restart Mark5B (Warren)
- 05:48 synced Mark5B (Warren)
- 06:39 Mark5B responding but producing connection errors. Rebooted and resynched. First good scan no0131 (Ross)
- 15:53UT mk5 has konked out again, first restart has not helped, trying a second restart now, First scan affected no0220 (Tiege)
- 16:27UT Second restart caused the mk5 to not want to rise from the dead, called Yg and they manually power cycled. This didnt fix it, so IP power cycled one more time. This time everything appears to be running OK. First good scan should be No0230 (Tiege)
- 17:03UT It was not running OK, called Jamie, seems to be running okay now as of scan No0236. Jamie believes it is something to do with there being 2 modules in the Yg mk5. (Tiege)
- 17:40UT Errors + alarms are back again and drives are stuck, going to leave it until morning for a fix as once its up again there will be only 45 mins left of experiment (assuming it works first try…) (Tiege)
