Hobart 12m:

Disk VSN: HOB+0127

Data volume at beginning: 0 GB

• Experiment started ok.
• 23:00UT: Sharp spike in band 13 autocorrelation function (Ross).
• 12:38 UT - disk_pos is ~70 gb short (vk)
• 13:52 UT - ~100 GB short (vk)

Katherine 12m:

Disk VSN: HOB+0129

Data volume at beginning: 0 GB. Now -50GB due to late start

• Experiment started 20 min late. Clock offset were heavily drifting. Had to restart the DBBC. Look good now (Lucia)
• 12:38 UT - disk_pos is ~70 gb short (vk)
• 13:35 UT - disk_pos is ~70 gb short (vk)

Yarragadee 12m:

Disk VSN: HOB+0123

Data volume at beginning: 0 GB

• Experiment started ok.
• 17:15UT: Yg called and reported a power failure, they run on the generator for the next ~1h. Observing look fine (Lucia)
• Problems with Tsys readings as usual.
• 23:00UT: Upon typing clkoff and maserdelay commands, delay difference worked out as 10^6 seconds. Repeated and sensible but this problem has occurred before (Ross).
• 23:15UT: Disk_pos 100GB behind schedule (Ross).
• 01:08UT: Disk_pos 135GB behind schedule, Jamie fixed issue with delayed start of recording (Ross).
• 1028UT: Antenna connection crashed, reopened at 1034UT (JS)
• 1238 UT - It looks like internet connection to Yg has fallen out. Cannot seem to call them even. Will try pining in a few minutes.
• 13:53 UT - Internet connection re-established. D-link modem restarted. Disk_pos is now ~200 behind prediction (vk)

Hart 15m:

• ERC couldn't get connection. Monitoring since 18UT.
