I live in rural very northern England. It’s incredible, clear with the naked eye. iPhone 14 camera with 3s exposure is out of this world (pun intended, but misleading)

Since we're all scientists here, I'll report a negative from central York. My wife and I stood up in the attic looking out of the Velux for 10 minutes. It was dark, clear and we were could see from NE-ish to SE-ish. We couldn't really call it. A very subtle effect on a 10s smartphone exposure, mayyybe? I will compare with tonight. We once rented a beautiful, slightly remote house on a beach outside Reykjavik and one…

I’m 5 miles to the east ! (Dunnington) and was gutted to hear this morning that I’d missed an amazing display here last night. Many people in the village saw the aurora in varied colours - greens, purples, pinks. Incredible photos… it sounds like it was just before midnight that it really kicked off.

Most of Europe == Not covered by light polution. (and specific areas) (it's orange outside and it's sodium vapor related) edit: kind of whish I was at my parent's place. It's a lot less poluted but no go here; nw europe densly populated, we also have the artificial sunrise here 24/7 by means of greenhouses.

Well, I was watching it in East London last night

Many of the photos here show it in such vivid colour, but for me the really breathtaking part was the scale and movement of the aurora.

Last night (here in Quebec) the entire sky was filled with colour. It's not as intense in person, but the slow shimmer of it is otherworldly. I was up on my roof for almost an hour, watching the blobs undulate in the sky. I think it made a bigger impression on me than the recent eclipse.

I feel I need to report my experience from Denmark, Jutland. It started with white broad streaks, which most of all looked like fog, but then perhaps after 10 minutes or so, we saw colors of red, purple and green begin to emerge from the these streaks. Most astoundingly it all seemed to emanate from a fluctuating point in the middle of the sky. If you looked closely at this point you could see it fall into itself, mo…

Poetry comes to us when we can’t say exactly how it made us feel. As a son of Jurgen, I appreciated your account.

Wait no way? That’s where the pirate eye patch trope comes from? There was a practical reason?

I had assumed it was because, being a pirate, you were more likely to have had one of your eyes poked out during some sort of mêlée. But that’s much more interesting…

This would explain why only pirates wear them rather than also ordinary seamen.

Not for long. The earth's magnetic field is decaying at an exponential rate as the poles shift. I believe we've spent far too much time worrying about CO2 and not nearly enough worrying about the dangers from our sun.

Got any scientific sources for that claim? > I believe we've spent far too much time worrying about CO2 and not nearly enough worrying about the dangers from our sun. Other than hardening our power grid to the effects of solar storms, what exactly could we do WRT the sun and the magnetic field? Also, given our serious lack of progress…

I wonder what you (or any of us) would like to say to N. J. Ayuk, Executive Chairman at the African Energy Chamber:- (his words, not mine)

“Africans don’t hate Oil and Gas companies. We love Oil and today we love gas even more because we know gas will give us a chance to industrialize. No country has ever been developed by fancy wind and green hydrogen. Africans see Oil and Gas as a path to success and a solution to their problems. The demonization of oil and gas companies will not work.”

and this is very far from an isolated opinion in the developing world. Given the amount of Western human capital applied to reducing dependence on fossil fuel it's a somewhat sobering experience to take a look at the Mauna Loa CO2 rate of increase. Can you see any significant decrease in recent years. I can't.

Ok why is it that some people say northern lights look EXACTLY like these spectacular photos, and others say in real life they are actually barely visible and you need a camera and very dark skies? Is there some kind of running joke I’m missing? I saw some northern lights in Iceland but they were very dim and underwhelming, I didn’t even know what I was looking at until I photographed them and saw the vivid green str…

Yeah, typically northern lights look like faint white clouds with a little bit of green tint to naked eye. The photos are like those time-exposure photos of the milky way, which is not what the eye sees.

You should try seeing the milky way from the middle of an ocean sometime - most folks have never been far enough from light pollution to really see it as it used to be.

It really does look like a river of starlight across the sky, once you are a few hundred miles away from shore.

There's no evidence that this use was real. Mythbusters tried it and said the trick itself does work (which any of has may already know), but who knows if it was even practical in a pirate boat, vs the loss of stereo vision etc. The whole idea of pirates wearing eyepatches seems simply the replication of one particularly colorful pirate archetype over centuries of literature and tales.

I feel like the advantages of stereo vision may be oversold in this scenario. At the distances that sailing vessels would engage there's limited need for binocular depth cues - they really only start to come into play at the point where you would begin a boarding action
