I wonder if we're going to see an aurora over Seattle tonight?

Too much light pollution. You'd have to get well outside of the city. I looked at the weather last night and I think there might have been some trails on Tiger where you would've seen it with headlamp off.

In Seattle you can barely see planets.

I'll be going out tonight if this continues into Australian night time hours.

At this strength, I could see the full display including colors with my naked eye in Melbourne, May 11th 2024. This storm is slightly stronger than that event.

I'll be attempting to get some photos/footage from Esperance.

There's a high triple threat bar for Astro photos sourced from Western Australia.

If you manage to pull off the Aurora Australis above a triple curl at The Right with a shark body surfing into the green room ... the internet will explode.

Hopefully it's clear space weather for Artemis II coming up. I wonder what they do if it's inclement en route?

There's not that much they can do. It's often discussed that if the extreme August 1972 solar storm had overlapped with an Apollo mission (it didn't), it would have acutely sickened the astronauts.

https://en.wikipedia.org/wiki/August_1972_solar_storms#Human...

> "Had a mission been taking place during August, those inside the Apollo command module would have been shielded from 90% of the incoming radiation. However, this reduced dose could still have caused acute radiation sickness if the astronauts were located outside the protective magnetic field of Earth, which was the case for much of a lunar mission. An astronaut engaged in EVA in orbit or on a moonwalk could have experienced severe radiation poisoning, or even absorbed a potentially lethal dose."

The Orion capsule's contingency plan looks something like this:

> "To protect themselves, astronauts will position themselves in the central part of the crew module largely reserved for storing items they’ll need during flight and create a shelter using the stowage bags on board. The method protects the crew by increasing mass directly surrounding them, and therefore making a denser environment that solar particles would have to travel through, while not adding mass to the crew module itself."

For All Mankind “illustrated” a solar storm at surface-level of the moon, including “boiling” regolith. I wonder how embellished this was, or whether particle bombardment would actually cause this.

My mind goes to the working mechanism of eidophor projectors, where oil on the projection bowl does indeed deform under electron beam exposure.

Possible aurora visible through central US tonight

Might be a coincidence but for the first time last night, my son's sleep projector[0] didn't stop after 1h like it does normally.

I guess this could be related to it? (we are in Montreal)

I doubt these toys are protected from those kinds of events.

It seems that the peak was several hours ago, and I haven't observed any effects from it...

The peak was originally supposed to be 6-7 hours from now... it's still showing KP 8 here though, so I'm not sure what's going on. It could get more intense.

Darn Montreal is still too south. Wish I were in Winnipeg.

I live somewhat close to the arctic circle and the aurora has been exceptional lately. One recent evening it looked like there was a massive city behind the cloud cover, and a few nights before when the sky was clear I watched enormous green flames for hours.

Aha, you probably witnessed a glimpse of Cittàgazze. You can capture it in photograms with a special emulsion: https://hisdarkmaterials.fandom.com/wiki/Aurora?file=Citt%C3...

any effects on the human body??

Depends. If you're outside at night and tilt your head up, the Default Mode Network of your brain may be temporarily suppressed, while dopamine may increase.

We never get aurora in Japan :(

Hokkaido got some back in November: https://www.asahi.com/ajw/articles/16155623

Yeah I figure Hokkaido may get a taste but we here in Honshu never do :'(
