The sky has been lighting up in North America too. I’ve heard reports of the aurora from New England and, here in the Pacific Northwest, it’s currently visible by naked eye and striking in long exposure shots. I always thought I would have to visit Alaska or Scandinavia to see the northern lights, never thought I could catch a glimpse so close to home.

It was visible as far south as northern San Antonio last night.

Earlier quoted context omitted.

A couple of years ago in the middle of Norway (not south, not north, in-between) me and a friend saw in the news that there would be aurora borealis, which is not common in that part of Norway. We were outside at like 2AM in the night that day trying to spot it but could see any hint of it for the life of us. Finally we used his phone and long exposure to see what it would pick up and on the captured photo we saw sha…

For what it's worth... growing up in Tromsø, we have auroras a few dozen times per winter usually. They were always strong enough to be easily seen, often quite dramatic. It really does look like that if you're far enough north.

I was lucky enough to be in Tromsø in February 2013 during the last solar cycle maximum. It was absolutely amazing, even a local who we happened upon near one of the fjords while he was cross country skiing - in the middle of the night - said that he had never seen such aurora. They were gold and purple along with the more common greens and reds that we had seen all week.

How long ahead of time can one forecast these events?

Realistically only about half an hour. There are instruments at the L1 lagrange point that can measure the properties of the solar wind and/or CME as they pass and allowed real informed responses to events.

There are also very, very simplified CME propagation models (WSA-ENLIL, etc) that can start with some assumptions and give a reasonable idea about when the CME will arrive within ~12 hours.

But for every time the simulations succesfully predict severe geomagnetic events or the like they give false positives a couple dozen times. The simulations cannot predict the geoeffectiveness.

i have the unique experience of being in a plane over the Bering sea a few hours ago. https://twitter.com/JeremyRubin/status/1789273537179426922 i was going nuts in my seat and seemed to be the only one on the plane aware of what was going on.

Ive had a similar experience but looking at massive forest fires outside and noone in the cabin caring in the least bit. Its a strange thing.

I’ve got a flight tonight at 23:00 so hopefully can secure a window seat!

Went about an hour north of Vancouver BC Canada to get away from bit city lights and watch.

It was probably not the brightest small strands I've ever seen - if my memories of Northern Saskatchewan as a kid are still accurate - but I don't think I've seen the whole sky light up to such an extent.

here's a photo: https://www.reddit.com/media?url=https%3A%2F%2Fi.redd.it%2Fu...

magenta and green colours were clearly visible in person during the intense periods, although obviously not as bright or intense as long exposure photos. Solidly visible bands for at least the two hours I stayed out.
