 +  * Some wind stows. Check logs to note off source times. (Jim) 
 +  * 2017.013.06:​14:​55 ALARM: Large difference between formatter and maser delays. Check for stability of new offset. Reconfigured dbbc. This seemed to work. Hobart was wind-stowed anyway (Lucas) 
 +  * 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=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)
