2025-11-12YESTERDAY'S X-5 FLARE

Posted on 2025-11-12 by Librarian

And most of you probably saw in various news reports there was an X-5 Flare yesterday which produced a significant CME that arrived at Earth last night just as two other, smaller, CMEs arrived.

The result was a some rather spectacular Northern Lights that were seen as far south as here in North Carolina. We personally couldn’t view them as we live in the woods and would have had to drive to the beach late at night to get a clear view of the Northern sky. Plenty of people are posting images of them in every Social Media network.

I ran across this article this morning while drinking my tea and thought I’d post it. What’s notable about it, at least to my mind, is the lack of real understanding of that which he is writing about. Sort of in line with “Oh look a two headed calf!” It has a decent write up of what flares and CME are and even references the Carrington Event so the writer did so his research.

What really struck me though was the line…”We are, quite literally, one severe solar storm away from living off-grid.”

“Living off-grid”?… Not… a Total Collapse of Technological Civilization? Not… the death of 95% of the the Human Race? Not… a worldwide collapse into barbarism and anarchy?

“…living off-grid.” Sounds almost…. Romantic.

Still, all in all it’s a decent article, which does address the issue well up to that point.
