Geomagnetic Storm Watch Issued for Earth for Sunday
weatherboy.com ^ | SEPTEMBER 24, 2021

Posted on 09/25/2021 5:35:58 PM PDT by BenLurkin

The Space Weather Prediction Center (SWPC) , a unit of the U.S. Department of Commerce under NOAA,which sits alongside its terrestrial National Weather Service, has issued a Geomagnetic Storm Watch for all of Earth for Sunday, September 26 for the possibility of G1 or G2 storm conditions.

On Thursday, a sunspot, known as AR2871, experienced two explosive eruptions, each producing a significant M-class solar flare. Solar flares are classified according to their strength, on a B-C-M-X scale. B flares are the smallest while X are the largest. Similar to the Richter scale used to help quantify earthquakes, each letter represents a ten-fold increase in energy output. Within each letter class, there is also a finer scale that usually extends from 1-9. Within the powerful X class of flares, the number could exceed 9 to reflect a massive flare event.

...

AR2871 initially produced a M1.8 flare and a subsequent coronal mass ejection (CME). According to the SWPC, initial analysis and model run indicate an overtaking of the slightly slower CME that was also produced by region 2871 earlier on the 23rd with an arrival anticipated for the first half of September 27.

A coronal hole high speed stream, known as CH HSS for short, is due to hit the Earth by midday on the 26th. The National Weather Service’s Space Weather Prediction Center (SWPC) says, “Isolated G1 (Minor) geomagnetic storming is likely 26 September as a positive polarity CH HSS extension from the Northern crown becomes geoeffective.”

Right now, the SWPC says there is a 30% chance of only active geomagnetic activity on the 26th, a 40% chance of a “minor storm”, a 25% chance of a “moderate storm”, and a 1% chance of a “strong-extreme storm.”

Trust science. This is the best that they can do with billion dollar budgets. Weather.com, which is wrong except in hindsight, could do that poorly.

No. Probably not Detroit either.

“So, I should stay up tonite and re-read “One Second After”?”

Or you could watch Melancholia on Hulu. That’s kind of close. I think Pufeflix has the Left Behind series....

There's a midday somewhere on the Earth all day

The last time this happened, I was at work in a VOIP teleconference. Got a lot of static throughout.

I asked my husband if we needed to do anything re: disconnecting from the grid. He said he got in prayer a few days ago, out of the blue, that a circuit breaker is not a switch, so I guess I’ll just unplg a few things.

What brand panels are you seeing fail you ?

Please share with the world, or at least freep mail me the brand and model numbers.

Just finished installing 64 new panels made in Texas last month.

fyi — my 10 year old panels are doing fine. Seem to be at least 90% of what they were new. Hard to really compare as over time I change things !!

btw — don’t buy any Fronius inverters. After ten years and two 5 kw installed, we are on like #6 between the two under warranty. I’m on my own in another month.

Does it count if my wife said to me ? “Too the moon” aka Ralph

Sounds like it’s time to lawyer up.

If she sends you to the dark side of the moon your Pv panels will be safe.
