| - | - Hobart 26m : We are experiencing occasional formatter problems which Jamie suspects are due to timing distribution issues. Further investigation is needed (action: Jamie, Brett) | + | - Items arising: |
| - | - On one or two experiments recently we've been getting close to module capacity or just going over. More care needed to make sure modules are big enough (action Jim, Jamie) | + | - Hb has had a couple of experiments recently where data were lost because the delay through the DBBC and Mark5 was unstable and drifting. The only solution seems to be power-cycling the DBBC. Please keep a close eye on the delay difference. [[operations:starting_monitoring_9.10.5|Documentation on what to look out for and how to monitor it is here]]. See the section "clkoff reading is drifting or far from the maser-GPS offset". |
| - | - Sometimes we send Hb or Ho data to Japan for Ultra-rapid experiments. Sometimes we forget to notify observers that they are on, and, as the procedure files are slightly different, no data are sent on the network. Ultra-Rapid experiments should be tagged in the schedule and observers notified (action Jim) | + | - Hobart 26m : We are experiencing occasional formatter problems which Jamie suspects are due to timing distribution issues.

| - | - The Ke control room needs an internal light that can be turned on/off remotely so observers can read the Mark5 module VSNs at night. (Action Brett, Martin) | + | - On one or two experiments recently we've been getting close to module capacity or just going over. More care needed to make sure modules are big enough (action Jim, Jamie) |
| - | - Yg earthing has been changed recently (following Brett's maintenance visit, completed July 31) and there's been a great improvement. However there were multiple clock drifts/jumps during R4599 and another one after setup for CRF77, but before it started, then again at ~04:15 UT (0.03 us). Please continue to watch out for clock jumps and note times. More discussions with MOBLAS staff needed to try and improve things. | + | - Sometimes we send Hb or Ho data to Japan for Ultra-rapid experiments.
