I saw this in the Denver area in Colorado, US an hour and a half ago. I looked up and couldn’t believe the sky was red. Took me a while to realize it was the aurora borealis. Very cool!

15 min ago I saw it north from Denver - half of the sky was red.

I know there are a lot of comments from people saying they’ve seen it, but as I understand it this solar flare won’t hit until 16h UTC, or about 12 hours from now, and there are two weaker flares hitting about now that are currently visible? Is that understanding correct?

So - even bigger tomorrow? Tonight was pretty amazing.

Checking in from Littleton - saw it as well! My friend all the way from Grand Junction CO posted photos too

Earlier quoted context omitted.

So .. they don't see scotland as part of the UK anyway? Why was it such an issue then that they wanted to leave? (And why were there bloody wars fought about it in the first place?)

Who wanted to leave? What wars?

Scotland the UK? (They were allowed to vote in the end and voted to remain)

And wars happened when scotland was forced to become part of the UK in medieval times. (Braveheart)

US power grid info:

PJM:

    Geomagnetic Disturbance Warning 
    11.11.2025 19:25 (PJM times are Eastern Standard).

    PJM-RTO
 
A Geomagnetic Disturbance Warning has been issued for 19:25 on 11.11.2025 through 04:00 on 11.12.2025 . A GMD warning of K7 or greater is in effect for this period.

This is only a warning. There are no listed actions being taken. When you see Geomagnetic Disturbance Action, not just Warning, there's a problem. That happened most recently on June 1, 2025. Extra people are probably on standby all night in case something happens.

CAISO: Nothing.

ERCOT: Nothing.

Hydro-Québec: Multiple snow-related outages near Montreal and some other locations.
