Travelling slowly, eyeballing it, somewhere between 10-20k kilometres up if in orbit. Altitude would be consistent with the flare duration, it disappeared out of sunlight within 2 minutes. Heading was about 130-150. Passed pretty much right overhead, perhaps a little southwest of me. Looking at today's launches, doesn't seem like anything would be above Warsaw at this time. Any ideas?

Same exact thing but northwest in Bosnia(21:15)It appeared to be red moving in strange directions.I actually followed and wrote it down,was too faint to record.First it appeared to my eye about few degrees above horizon after that as it was rising in sky it grew brighter and brighter almost as bright as Jupiter.Then it reached its peak of 30° above the horizon and appeared to go back down gradually becoming fainter and fainter and repeating same motion.Strangest thing I ever experienced,any ideas
Rocket Fuel becoming plasma in the upper atmosphere.
Kinda looks the theoretical swirl of a Wormhole.
Could be someone (or something) using some sort of gate technology we’re unaware of (for now).
Fuel dump from a falcon 9 upper stage before it de orbits, the stage will be rotating during this process hence the spiraling effect
Please be an alien invasion. Please. Andromeda, you’re our only hope!
Falcon launch venting excess fuel before burn back
10-20k kilometers… altitude? Where did you get these numbers?
Weird, someone else just posted about it too. No indication where they are location, though, as far as I can tell.

The star right next to it is Capella/Alhajoth, you can find it using the Skyview app.
Should be visible if you are in Europe and look roughly up and towards North-West.
Also if you don’t have cloud coverage.
> 10-20k kilometres up
A great example how people are completely hopeless at estimating distances. It’s Falcon 9 upper stage deorbiting. You were off by just an order of magnitude.

Has everyone completely forgotten the Norway spiral? By far the most impressive of this phenomenon ever recorded. And it was a failed Russian SLBM test so extra interesting.
My friend literally rang me an hour ago to say he saw something weird in the sky. Both of us live north Manchester, UK. Even the Manchester evening news posted about it and within 20 mins which is strangely fast for them
Just saw this in Oxford, UK a couple hours ago. News mentioned it is likely a fuel dump from a “spy satellite launched by spacex”.
Space X had a launch today
