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.

This is a Lunar Lander observation.
No schedules on IVS server by the beginning of the observation, experiment started late. First scan: 250-1742 to source 0308-611 @ 280.17:42:46.00
Receiver 20K stage is hotter than 40K
LO unlocked at:
2014.280.21:14:28.44?ERROR ch -348 Receiver LO is unlocked
2014.280.21:14:49.51?ERROR ch -348 Receiver LO is unlocked
2014.280.21:15:10.59?ERROR ch -348 Receiver LO is unlocked
2014.280.21:29:19.43?ERROR ch -348 Receiver LO is unlocked
Tried to repair LO unlocked by moving the antenna manually. Missed scans from 22:31:31 to 22:32:55
LO unlocked 281-02:24UT - Brett fixed by moving it a bit
281-02:32UT Temperatures were rising rapidly (along with vacuum pressure) so the schedule was halted so Brett can fix it. Scans after 281-0229 missed. 0337 first scan back.
2014.281.09:00:28.49#rxp#Receiver focus X : -255.5mm ; Y : 250.8mm ; Z : 18.6mm – Y position is a bit off (should be: 248mm); He supply pressure fell from 307psi to 302psi in 4 hours

monitoring on ops4 due to problems with screens on ops2, as reported by Warren (Lucia-09:00)
Unexpected shutdowns of econtrol for Ke & Yg (Lucia-09:00)& Hb (10:30, L). When Hb is gone, need to close all other erc, start Hb first.
