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.

Yarragadee 12m
Disk VSN: HOB+0116/16000/1024| Data volume at beginning: 6728 GB
- 1800UT Experiment started OK (David Schunck)
- 0600UT Getting persistent errors “previous source in schedule not reached”, as well as some warnings “time window exceeded 0.25 seconds …”, and messages in fs saying antenna stuck/antenna moving repeatedly. Warren says there is no easy fix as the antenna is playing up. Only thing we can do is check that the azimuth and elevation coordinates are regularly moving to new sources on timeyg. (Eloise)
Hobart 26
- 1800UT S/X receiver is not on axis. The focus is stuck. Hobart26 will join the OHG142 once the S/X receiver is on axis.
- 2234UT sx on axis first source (warren)

Hobart 12m
Disk VSN: flexbuf-2hb | Data volume at beginning: GB
- 1830UT Experiment started okay (Lim).
- 0610UT Alarm: Large difference between formatter and maser delays. Check for stability of new offset. Checked new offsets and the alarm showed up again. Reconfigured the dbbc3hb. Affected scans: 083-0609 to 083-0710a (Simin).
- 0815UT Alarm: Large difference between formatter and maser delays. Check for stability of new offset. Happened again after the reconfiguration of the dbbc3hb. Jamie had a look at it. It seems serious and linked to the maser (Maser pps/ 10 MHz is drifting). Nothing can be done so the schedule halted and terminate (Simin)

Disk VSN: MAT+0003 | Data volume at beginning: 1063.33 GB
- 1830UT Experiment started okay. There's issue with tracking so probably most scan will not be “TRACKING”. (Lim).
