| + | * 10:30 UT Hobart recovered from 'wind stow'. | ||
| + | * Antenna probably hadn't been wind stowed actually for a while. I noticed the wind speed had dropped to 7.5km/h bu the antenna hadn't recovered. | ||
| + | * Anyway after a few resets of antenna, drives, reboots, system and no change I thought the monica data was wrong since the wind speed didn't change from 7.5km/h. This has worked for me in the past to I tried it first. | ||
| + | * Antenna started setting off alarms due to missed scans and started trying to record data whilst stowed. Never a good sign. Solution was to: | ||
| + | * halt | ||
| + | * disk-record=off | ||
| + | * antenna=off | ||
| + | * terminate fs | ||
| + | * restart | ||
| + | * antenna=open | ||
| + | * antenna=operate | ||
| + | * proc=r4774hb | ||
| + | * schedule=r4774 | ||
| + | And it was away! | ||
| + | * First good scan after recovery 013-1039. | ||
| + | * **IMPORTANT NOTE** I skimmed the logs to see where it went wrong and I think the moment it buggered up was a note that said 'auto-stow recovery failed'. From then on it got stuck in a loop of trying to stow but never getting there. Maybe this should be an alarm?? | ||
| + | * 14:30 Automatic wind stow. Released on it's own. 013-1451 first scan after release. | ||
| + | * 15:20 I think monica weather server isn't working, wind data hasn't updated for a while. I needed to go up to the telescope (to put in a mv004 module) and the wind was very clearly >7.7km/h (it nearly blew me over) that the monitor system showed (Lucas) | ||
| + | * 15:30 Auto-stow released, source 1144-379, but probably not for long (Lucas) | ||
