7-Day Arctic Tour for B-46 Balloon

A long duration foil party balloon transmitting Contestia 8/250 telemetry data on 434.500 MHz USB was launched on Friday, April 18 from Silverstone in the UK by radio amateur Leo Bodnar M0XER. Its seven day journey has taken it to Iceland, Greenland across the Norwegian Sea and down into Finland.

According to the current projected course it may continue south into Russia and travel close to the Ukrainian border.

Depending on the altitude, the balloon could have a radio range of 300-500 km. See the current track of the balloon at http://spacenear.us/tracker/?filter=B-46
