Current storm is visible in Florida and Southern Texas, per NOAA.

Like, visible visible? I’m a lot farther north than that and if I hadn’t known there was something going on, I’d not have noticed it. It kinda shows up on camera, but naked eye viewing is not even worth a walk to the nearest window. Nothing to see, really.

Having your eyes dark-adapted (even a bit) makes a big difference. Here (Maine) I couldn't see anything out the window, or much of anything stepping outside, but after two minutes could see large-scale aurora across the entire sky, despite being near a bunch of streetlights and passing cars.

This is related to the cycles of Earth’s core Our planet’s magnetic field is “entangled” with the Sun’s activity This unusual flare means unusual activity for our magnetic field, hence for the core as well It would be cool to have some realtime comparison/visualization of Earths magnetic core activity, vs solar flares

Could you provide sources for this? Sounds plausible, given it is electromagnetic energy.

Just speculating

It’s known that the magnetic core is generating/sustaining the magnetic field, which means that anything that happens to the field, has some sort of counterpart in the core

So it would be cool to have that data: what happens inside Earth’s core when a big magnetic event is affecting it’s magnetic field

Doesn’t look like that in reality. If I take a photo on my phone here in the UK midlands I get pink and green in all directions with a 3 second exposure. However with just the naked eye it’s like super high level clouds

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…

One thing to consider is that when you run outside because you get a tip about northern lights, your eyes need about 20-30 minutes to fully adjust to darkness. If you do things like look at a phone display or camera display while waiting, that "timer" gets reset.

In my experience when the lights are strong (and your eyes have adjusted), they look a lot like the photos - not as saturated color-wise, but very bright.
