CORRECTION: I’d forgotten that I rotated the movie. This is the Sun’s western edge, rather than the north pole.
(Sorry for being slow with reporting this. I’d hoped to make more content yesterday but have been dealing with a family emergency)
A strong geomagnetic storm could bring aurora down to mid-latitudes (perhaps even lower for short bursts), with no notable adverse effects on technology expected.

A beautiful filament of plasma erupted from near the Sun’s north pole today! Beautiful stuff.
Yesterday the Sun did this, and today we have the world’s largest solar telescope (the 4m diameter ‘Inouye Solar Telescope’) pointing at the same region for a few hours – as part of our solar flare observing proposal! Fingers crossed that the Sun’s fireworks continue today.
The Sun has really woken up today, with some beautiful edge-on filament eruptions addition to the Earth-directed solar flares we just experienced. Our local star is certainly beautiful!
Some snapshots:
Is the Sun firing blanks? In my most recent “Sunny Sci’d Up” Substack post, I discuss why it’s so hard to predict the arrival time of Earth-directed eruptions on the Sun! Link here: ryanjfrench.substack.com/p/is-the-sun...

For those who hadn’t seen already, there are currently three coronal mass ejections en route to the Earth (launched by solar flares on the Sun yesterday). We are expecting these eruptions to merge together, reaching Earth and triggering a strong geomagnetic storm tonight!
