05:41:00 : High Wind ALERTS at W05 and W06.
           Intermittently applying brakes.

07:15:00 : Due to high wind, W04 intermittent applying brakes.
07:35:00 : Due to high wind parked all antennas and stopped scan and 
command file because 2 mins average wind gone beyond 40kmph so 
ONLINE program WARNED to park an array.
11:00 : Observing session over.
