@g7izu So, what are the chances of a #CannibalCME at this point? Inquiring minds want to know.😎
Major Solar Flare (X9)
October 3, 2024 @ 13:50 UTC (UPDATED)
via #SolarHam
"A major X9.0 solar flare was just detected around Earth facing sunspot region #AR3842 at 12:18 UTC (Oct 3). This is the strongest X-Ray event of the current solar cycle. More details to follow regarding a possible CME.
"#CME Update: A coronal mass ejection (CME) with a halo signature is evident following the major X9.0 solar flare this morning. Because the source region AR 3842 is directly facing Earth, the plasma cloud appears to be aimed directly towards our planet. A further update will be provided later today once a CME tracking model becomes available. Please note that a faint CME associated with the X7 event on October 1st is expected to pass our planet sometime during the next few days.
"Aurora sky watchers at middle to high latitudes should have their camera batteries charged up should geomagnetic storming be observed as forecast."

Westport ObservatoryCANNIBAL CME ALERT: Multiple Coronal Mass Ejections are heading toward Earth following a series of strong M-class solar flares this weekend. Two of the CMEs may be merging to form a potent Cannibal CME. The action begins on July 30th and 31st when the CMEs are expected to arrive, possibly sparking strong G3-class geomagnetic storms. https://Spaceweather.com for the latest.

It's more about whether or not Earth's #magnetosphere is affected by the #GeomagneticStorm, rather than the #SolarFlares themselves.
Could an extremely powerful #SolarFlare destroy all the electronics on Earth?

"Because our atmosphere absorbs most of these dangerous rays, terrestrial systems are fairly safe from solar flares. But another solar event called a coronal mass ejection (#CME) can cause serious problems for electrical systems here on Earth. During a CME, the fluctuations of the sun's magnetic fields cause a large portion of the surface of the sun to expand rapidly, ejecting billions of tons of particles out into space.
"Sometimes CMEs accompany solar flares -- but not all solar flares produce #CMEs and not all CMEs accompany solar flares.
"Unlike a solar flare, a CME doesn't produce intense light. But it does produce a magnetic shockwave that extends billions of miles out into space. If Earth is in the path of that shockwave, our planet's magnetic field will react to the event. It's similar to what happens if you put a weak magnet next to a strong one. The weak magnet's field will align itself to the strong magnet's field. A magnetic shockwave from the sun could cause the alignment of the Earth's magnetic field to shift unpredictably.
"Pretty lights aren't the only consequence from a CME. The magnetic fluctuations can cause compasses to fail. And since magnetic fields can induce electricity, any conductor could become an inductor. A powerful CME could induce electricity in large, powerful conductors. That could overload electrical systems and cause massive damage."

@QuadRadical So, basically, if you are able to call your phone in whatever you're using as a #FaradayCage, it's NOT going to be effective against #EMPs.
"Trefethen also points out that microwave ovens, despite their thick wires, are not perfect Faraday cages. That is because if you put your mobile phone – which communicates via microwaves – into an oven and call it, it will almost certainly ring."
#SolarFlare #SolarFlares #SolarCycle25 #CMEs #CannibalCME #CarringtonEvent
@QuadRadical Here we go...
"There are some examples of Faraday cages that we use these days. Faraday cages can be quite complex or very simple, ranging from a shoebox to an entire building. Wrapping your phone in plastic and then wrapping it in aluminum foil, for example, creates a makeshift #FaradayCage."

@QuadRadical Hmmmm... That may not work... I'd say maybe wrapping stuff up in aluminum foil might provide more protection. Wrapping them in foil and put them in the microwave *might* work.
"A microwave is an electric oven that heats and cooks food by exposing it to microwave-frequency electromagnetic radiation. People use this to heat their foods quickly, and some are curious if microwaves can classify as an example of Faraday cages.
"This article will show you what a faraday cage is and if a microwave is considered a faraday cage.
Is a Microwave a #FaradayCage?
"Simply put, Faraday Cages disperse electrostatic charge around their perimeter. As a result, they act as a barrier to anything within them.
"In this regard, they are a hollow conductor in which the electromagnetic charge remains only on the cage’s external surface. But, as with many things, the reality is a little more complicated.
"Microwave ovens are another common application for Faraday Cages. However, unlike other applications, they are designed to reverse and keep the microwave radiation within the oven. You can see a portion of the cage on the microwave oven’s transparent window.
"Microwaves nowadays are not built and designed as a Faraday cage, but rather a 1/4 wave choke that effectively attenuates 2.4 GHz but not other frequencies.
However,
"A Faraday cage is from any material that conducts electricity. This cage could be wire mesh, metallic sheets, or wire coils. They can be any shape, such as a box, sphere, or cylinder, and any size, ranging from extremely small to extremely large.
"According to Florida State University, the cage’s exterior can be as simple as aluminum foil. The outer covering, or conductor, can be as thin as foil, but thickening it will provide additional protection from more powerful electric fields."

I'm not sure what's going to happen, but I plan on making sure all my electronics are turned off and disconnected, and might put some of them in a makeshift #FaradayCage until after the #CMEs hit Earth. I'd like to think utilities and such will have learned from warnings from 2013, but then again, it's the human race we're talking about. Unless there's a buck to be made, we seem to be woefully unprepared for stuff that can happen -- unfortunately...
"If a massive CME were spotted, such 3-day forecasts give us some lead time: there are some measures #ElectricUtilities could take to protect their equipment, such as quickly disconnecting #transformers. Polar flights, which travel at the highest altitudes, could be rerouted to avoid contact with damaging solar particles, and some #satellites could be switched into a #SafeMode to minimize damage. Here on Earth, at the very least, we’d have some time to prepare for potential power #blackouts and other problems."
