America, Headed Your Way!
The K6RPT-12 long-duration high-altitude balloon left the North American
mainland, after crossing directly over Halifax, Nova Scotia, Canada at
approximately 17:35 US EDT (2230 UTC 2 December).
It's heading out almost straight east across the Atlantic ocean at about 210
MPH (340 KM/h) at aproximately 110,000 feet (33,500 meters). At it's
present rate of travel, we will have about another 90 minutes to two hours
before it goes out of range of igates in North America.
Tune your igate receivers to the North American APRS channel of 144.39 MHz
by around 0200-0300 UTC 3 December to try to igate it.
The flight is having problems with the GPS receiver constantly unlocking and
relocking, yielding a rather odd saw-tooth-like track. The true track is
easily discernible, if you ignore or filter out the beacons with an
elevation near sea level.
