All of this and the only image linked is a collage clocking in at a whopping 512x218px...anyone know where we can see the full resolution? It looks spectacular from the thumbnail!

Yeah, annoying.

This one is better:

Took me a bit of time to realise this wasn't about spotting a plane from the ISS... which is apparently possible but difficult:

why is it red?
somat•44m ago
Best guess, high altitude atomic oxygen.

Based on the wikipedia aurora article it sounds like the lower atmosphere has a more mixed bag of gasses, so it glows white, while in the upper atmosphere atomic oxygen(note that oxygen lower down is all diatomic and glows green) is able to showcase it's characteristic red glow.

https://en.wikipedia.org/wiki/Aurora#Colours_and_wavelengths...

But now I am wondering about the green(oxygen?) and yellow(sodium?) atmospheric bands visable. The green one is interesting because it may tear apart my atomic oxygen theory. why would a green diatomic band be above the red atomic sprite flare?

Pilot had been reporting things like that for years but nobody would believe them because they weren't "trained observers", until a pilot caught it on film in the 80's.

Same with sailors, who've been repairing rogue waves for centuries, but it wasn't until it was recorded scientifically on an oil rig that scientists took it seriously.

Still an awesome picture.

In 1995 or 1997, can't remember which, I flew from Belo Horizonte to Miami (if the former) or NYC (latter). When we were flying over what I think is the Caribbean, I recall seeing "upward lightnings". They were absolutely majestic. I was absolutely awaken. I don't remember much else as I was a kid but seeing this text made me come back to this beautiful memory.

> but nobody would believe them

Pretty well understood today. Dunno, why "OMG, they would have never known this back in 123, if not for this one trick!", is relevant. That is true for everything. If you are writing a popular science novel, maybe people will care that someone once upon a time wouldn't have known this, but now we do!

> In ensuing decades, high altitude electrical discharges were reported by aircraft pilots and discounted by meteorologists until the first direct visual evidence was documented in 1989.

From your link.

N2yhWNXQN3k9•42m ago
Your point being... what?
wfme•34m ago
It was in response to your original, unedited comment: "Pretty well understood" or something to that effect.

My point is that discounting historical accounts with a link to current information is neither particularly useful nor interesting.

IMO it is much more interesting to understand how our understanding has changed over time.

N2yhWNXQN3k9•31m ago
The link also contains information of the history of the current understanding? And is a direct summary of current understanding? I guess that contains your constraints for an interesting article (as it includes historical and current references that cover said history). So, what am I missing?

Also, I didn't edit the main premise of the comment, as it still contains the phrase "Pretty well understood today", unedited, but whatever.
