I thought the Drive's article was pretty good including details of a Canadian flight to (presumably) check on the balloon as it went over the Okanagon roughly.

Similar balloons appear to have been photographed in Hawaii, India (Andamans), Japan. A different type was recently photographed over the Philippines and there is a comment about use over Guam.
