Any chance it'll be there tomorrow too? Seems beautiful in the French alps, wonder if it's worth trying to go there tomorrow https://www.skaping.com/chamrousse/la-croix?archives=MTcxNTM...

There were some follow on flare events. "Additional activity expected"

If you want the best possible view with the naked eye, give them a chance to adapt to the dark properly. The human eye is about 100,000 more sensitive after an hour in total darkness. A smartphone screen or car headlight is enough to undo it.

car headlights are brighter than the sun from a short enough distance; perhaps you think we can guess what distance you're talking about seeing the car headline from, but actually you have to be explicit about it

Earlier quoted context omitted.

Can you share a photo?

I took one semi successful photo using my crappy beat-down a20e Samsung phone. It doesn't do what we saw justice at all. https://imgur.com/5mlD22W

grafelic's image looks totally black on my crappy laptop monitor unless I turn brightness up to 100%, even then it's barely noticeable.

Here's a color enhanced version of grafelic's photo that shows the color bands more easily,

Added some blur after color adjustments to remove pixelation artifacts.

Are we supposed to be able to see anything in North America?

In some places yes https://services.swpc.noaa.gov/images/aurora-forecast-northe...

Keep in mind, this is only a 30 minute leading forecast. And day-night status has a strong effect on the ionosphere, to the extent that radio stations have different regulated broadcast power day versus night, and amateur radio folks bounce radio off it at night.

In the dark notice how much light comes from a phone and how much that illuminates the person holding the phone.

A car headlight shining your way from hundreds of meters even over 1km will often illuminate that person far more than their phone screen.

So if the phone screen is enough to undo the hour long eyes adjusting to the dark duration, then the car headlights at almost any realistic distance causes an undo.

Anyone know of sources/sites that track the magnitude of geomagnetic storms as a time series? (interested to gauge the magnitude of recent ones relative to those of the past, similarly to how we may do so for earthquakes)

Perhaps not quite what you're looking for, but this might give you a start:
