Hi all,
Didn't know where to put this - kind of between local and deep sky I suppose. I spotted this last night at sunset and followed it for 2 hours.
I would be interested to know who launched it. It looks very much like a
NASA model as seen here. It has 36 ribs like the NASA balloon. These balloons can get up to 40 km high and wander around for very long periods of over a month or more.
I have images and a movie
here
