The marine buoy ZL1SIX with an Amateur radio package is being tracked as it moves around the Pacific Ocean.  Bob Sutton ZL1RS reports that at the mercy of the tides, currents and wind direction, the solar powered buoy is moving at an average of average speed of half a kilometre an hour.

Tracking is via its transmissions of data on the 30m band each hour on the weak signal WSPR and JT9 modes.  More details on the exciting project along with real-time mapping is available here.

At 00:00 UTC today (June 17th 2016) present position after 30 days in the ocean is AG15FD.  Direct line change from the launch point at RG93SQ: 334km at 062 degrees, average speed 0.46km/hr.
