Hi All

 

I was imaging Jupiter tonight, and during post in AS!4 of one of my captures, it picked up an anomaly.

 

So I looked at the .ser file, and found this... click to animate.

 

 

This is slowed by the Animated GIF output of PIPP to 3fps, but I was capturing at 200fps, and this thing just flies by - it takes 130 frames to cross - so about 650ms in real time.

 

At first, I thought balloon maybe?  But it stays quite spherical, and travels in a straight line.  Of course, given difference in apparent distance, it could actually be a balloon now that I think about it.

 

But for fun, any ideas?

 

Cheers

Liam

A balloon is all I can think of.  That's crazy.

Very interesting

Cool! --- yes, a weather balloon ~at altitude~... subtending a few arc sec. Nifty and interesting happenstance!    Tom

Might be that pesky Tesla Roadster again.

I haven't measured it but let'd say it subtends 5 arc-sec. That equates to 1 part in 83,000. So options are:

1) a 1 ft balloon at 83,000 ft. Seems too small. It would have started off being tiny, to expand to that diameter at that altitude.

2) a 13 ft 'sphere' in low-earth-orbit, 200 miles up. A bit of a satellite or rocket?
