- General Note: e-remote ctrl doesn't connect to newsmerd. Running new e-remote ctrl. Have had new erc crash upon submitting checklist. (Bryn)
- 17:50UT - He supply pressure hovering around 273 ish, has come up from low of 271 about 30 mins ago. Deemed not critical since middle of the night and experiment is about to finish. (Ellen)

- 1700UT - Good start, everything peachy (JS)
- 2200UT - Getting some DBBC offset drifts (JS)
- 2205UT - Reset DBBC during gap, still missed scans 159-2210,159-2212a (JS)
- 0030UT - Heater switched off in maser room (Approximate time given by Bret, may have been >0033UT) (JR)
- 0033UT - ALARM: Delay through DBBC has changed. Will monitor and reset DBBC if problem persists. (JR)
- 0825UT - ALARM: Delay through DBBC has changed. Monitoring for now (Tiege)
- 0836UT - Still drifting, Have halted the schedule and attempting to reset dbbc and fix the problem. Scans 160-0825, 160-0828a, 160-0834 were all undertaken during the drifting. (Tiege)
- 0908UT - Think I have fixed the issue, first two attempts at stopping the drifting were unsuccessful, drifting occurred again within minutes of resetting DBBC, additionally mk5 spat the dummy and dimino needed to be killed and restarted. Scans missed were 160-0836a through to 160-0910b inclusive. First good scan is 160-0918a. (Tiege)
- 2016.160.13:04:28 ALARM: Delay through DBBC has changed. Monitor for stability and reset DBBC if it drifts. (Lucas) Only one alarm so far but will reconfigure if it persists.
