Real Time Perseid
Explanation: Bright meteors and dark night skies made this year's Perseid meteor shower a great time for a weekend campout. And while packing away their equipment, skygazers at a campsite in the mountains of southern Germany found at least one more reason to linger under the stars, witnessing this brief but colorful flash with their own eyes.
Presented as a 50 frame gif, the two second long video was captured during the morning twilight of August 12. In real time it shows the development of the
typical green train of a bright Perseid meteor. A much fainter Perseid is just visible farther to the right.
Plowing through Earth's atmosphere at 60 kilometers per second, Perseids are fast enough to excite the characteristic green emission of atomic oxygen at altitudes of 100 kilometers or so.

There are TWO flashes to the right... one higher, and one lower, which does not seem to be moving... what is that???

If you look closer the second flash does move slightly. I think this object might be a satellite.
Just as zero is not equal to infinity, everything coming from nothing is illogical.

Could be. Or maybe a flashing light from an airplane?

I see movement on the ground that is not explained. I assume it is not relevant but it is distracting for me.
Oh, now we have to pass an intelligence test? This is new.

It is easy even for the very intelligent to overlook things:

Yes, that might even be more likely.
