I don't know if anyone else has noticed but for the last few days (weeks?) there has been an automatic weather buoy [AMOUK42] parked in Southampton. It's transmitting hourly SYNOP, here's the 1500 UTC one:

BBXX AMOUK42 1315/ 99509 70014 46/// ///// 10133 20078 40305=

I can only assume its in for a service and tied up at one of the quays.
