Experts Warn The #Internet Will Go Down In A Big Way — And You'd Better Be Ready
Story by Geoff Williams, 9/23/2025
"It’s bad enough when the internet goes down for a few hours because your power went out after a storm, but what if the internet went down indefinitely, sort of everywhere? What if your state or an entire region of the country lacked the internet or electricity because of a cyberattack or something innocuous, like problems with an aging grid or the federal government forgot to pay a bill?"

Even the sun is getting in on the #ExtremeWeather action! Yikes!
'The sun is slowly waking up': NASA warns that there may be more extreme #SpaceWeather for decades to come
NewsA new NASA study suggests that solar activity will remain high or rise further in the coming decades, contradicting previous assumptions that the sun was quieting down — and scientists "don't completely understand" why.
By Harry Baker, published September 17, 2025
"NASA scientists are warning that the sun may be "waking up" from a brief period of relative inactivity, contradicting past assumptions about our home star. If true, this could mean that decades of potentially dangerous space weather are in store.
[...]
"In a new study, published Sept. 8 in The Astrophysical Journal Letters, researchers analyzed multiple metrics of solar activity, including solar wind, magnetic field strength and sunspot numbers, and found that they have been on an upward trend since around 2008, and could rise further over future cycles, suggesting that the deep solar minimum theory is well and truly dead.
[...]
"During the current maximum, Earth has also been hit by several major geomagnetic storms, or disturbances to the planet's magnetic field. The most noteworthy was an 'extreme' event in May 2024, which triggered some of the most vibrant aurora displays in centuries and caused over $500 million in damages."

#SolarFlare update via #SolarHam
Another X-Flare
June 19, 2025 @ 23:55 UTC
"X-Flare Alert. Sunspot region 4114 just produced an X1.9 solar flare peaking at 23:50 UTC (Jun 19). Coronal dimming is not yet evident meaning a noteworthy #CME is unlikely. More to follow whenever necessary."

Millions of Americans Told to Stay Indoors After Rare X1.2-Class Solar Flare Eruption
Story by Michaele Allies
June 17, 2025"On June 17, 2025, the Sun unleashed a powerful X1.2-class solar flare from sunspot region 4114, which was directly facing Earth. This intense burst of energy prompted warnings for millions of Americans to stay indoors for three days due to increased radiation risks and communication disruptions. The flare caused immediate effects such as radio blackouts, especially over the Pacific Ocean and Hawaii, impacting aviation and amateur radio operations.
"This event underscores the importance of understanding solar flares, as they can significantly affect Earth's environment and modern technology, including satellites, power grids, and navigation systems. #NASA’s Solar Dynamics Observatory [#SDO] captured detailed imagery of the flare, while #NOAA issued alerts to help mitigate its impact. As solar activity intensifies during this solar cycle, such events remind us of the Sun’s power and the need for preparedness against space weather threats."

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?
By: Jonathan Strickland
Updated: Jun 9, 2023"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."

@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."

I hope those in charge of all this stuff are taking the CME threat seriously.
What Damage Could Be Caused by a Massive Solar Storm?
An enormous solar storm could short out telecom satellites, radio communications, and power grids, leading to trillions of dollars in damages, experts say
Joseph Stromberg
February 22, 2013"If a CME as large as the one that triggered the 1859 storm were to occur today, the consequences could be devastating. Given the increase in our reliance on electricity and telecommunications (even since 1989), the effects would certainly be far more significant than malfunctioning telegraph pylons.
"It’s hard to appreciate just how many aspects of modern life rely on technologies that could be affected. As Daniel Baker of the University of Colorado’s Laboratory for Atmospheric and Space Physics told National Geographic in 2011, 'Every time you purchase a gallon of gas with your credit card, that’s a satellite transaction.' A giant storm could disrupt our GPS systems, communication with planes in flight and other crucial satellite-based technologies.
"But the biggest concern, experts say, would be disruptions to our power grid—as a 2011 OECD report (PDF) on the impacts of solar storms points out, 'Electric power is modern society’s cornerstone technology on which virtually all other infrastructures and services depend.' A surge in solar wind can blow out power transformers by melting their copper windings, and especially in highly interconnected regions (such as the East Coast), transformer failures can trigger cascading effects, spreading power outages over wide areas.
"One analysis looked at a 1921 storm—which was ten times more powerful than the 1989 event—and estimated that if it occurred today, it would leave some 130 million people without power, potentially affecting water and food distribution, heating and air conditioning, sewage disposal and a host of other aspects of the infrastructure we take for granted daily. The total cost of an even larger storm, such as the 1859 event, could be enormous: an estimated $1 to $2 trillion in the first year alone, and a total recovery that could take 4 to 10 years in total."

#SpaceWeather update from Spaceweather.com
ARE WE ABOUT TO EXPERIENCE A NEW CARRINGTON EVENT?
"No. #AR3664 is indeed a '#Carrington-class' sunspot, but the #CMEs it hurled toward Earth over the past few days are not as potent as the monster CME of Sept. 1, 1859. NOAA says we might experience a severe geomagnetic storm when the CMEs arrive this weekend. If geomagnetic storms were hurricanes, 'severe' would be category 4. The Carrington Event was category 5 or greater. So this is no #CarringtonEvent. Even so, category 4 is pretty intense--if it happens.
"FIVE CMEs ARE HEADING FOR EARTH: Great sunspot AR3664 has hurled an astonishing five CMEs toward Earth.
"According to a NOAA forecast model, the first three CMEs could merge for form a 'Cannibal CME.' Cannibal CMEs form when fast-moving CMEs overtake and gobble up slower CMEs in front of them. Internal shock waves created by such CME collisions do an good job sparking geomagnetic storms when they strike Earth's magnetic field.
"The #CannibalCME is expected to arrive on May 11th. It alone could spark a strong (G3) #GeomagneticStorm. With two more CMEs following close behind, storm levels could become extreme (G4), sparking auroras at mid- to low-latitudes across Europe and the USA."
