“Here comes the sun”*…
Earth’s magnetic field provides an imperfect shield against solar stormsFurther, in a fashion, to last Wednesday’s post… We’ve looked before (e.g., here) at the potential havoc that solar storms could wreak on our electified lives. Now, as Paul Voosen reports, scientists are speculating on a defense, suggesting that gases released from satellites could slash the threat of severe “space weather”…
When violent eruptions from the Sun slam into Earth’s magnetic field, they do more than paint aurorae across the night sky. They can scramble the electronics of satellites and induce powerful ground currents that knock out electrical grids. It’s been estimated that a one-in-a-100-year solar storm like the 1859 Carrington Event could cause more than $3 trillion of damage to the power grid alone. [See here.]
Yet for decades, society’s only defenses have been better space weather forecasts and more durable technology on the ground and in space. Now, a small group of space physicists says humanity should intervene and weaken solar storms in real time. In a study published [recently] in Space Weather, the researchers describe a provocative proposal called “StormWall”: a fleet of satellites that would release hundreds of tons of gases into space just before a solar storm strikes Earth. Computer simulations suggest the artificial cloud could cut the intensity of a major solar storm by half or more. “It’s as if you could install an airbag in the magnetosphere,” says Daniel Welling, a co-author and space physicist at the University of Michigan.
Call it “helioengineering”—a deliberate intervention in the near-Earth space environment. But unlike controversial geoengineering proposals to mitigate global warming, which would inject long-lived Sun-blocking particles into the atmosphere, StormWall’s protective gases would dissipate within hours, says Brian Walsh, the study’s lead author and a space physicist at Boston University. “It’s waiting for us to do some temporary modification.”
The proposal would require more extensive simulations and testing. But it is “highly innovative and appears to be quite feasible in the near term,” says Allison Jaynes, a space physicist at the University of Iowa. It’s a “laudable idea,” adds Gurudas Ganguli, a space physicist at the U.S. Naval Research Laboratory (NRL)…
[Voosen explains the technology proposed and considers the challenges in its implementation…]
… Of course, like an airbag, StormWall would have to be replaced if deployed. But just as NASA and other space agencies are studying how to protect the planet from asteroids [and here], Walsh says there’s a good argument for fortifying an electronics-dependent society against massive solar eruptions. “If we lose all our power grids and can’t use the internet for 6 years, it would be traumatic.”
“Radical proposal would block solar storms with orbital ‘airbag’” from @science.org.

As we apply sunscreen, we might send bright birthday greetings to Godfried Wendelen; he was born on this date in 1580. And astronomer (and Catholic priest) known as “the Ptolemy of his time.” Despite the tenets of his church, Wendelen was an audacious proponent of the Copernican theory that the planets orbit around the sun. He made more accurate measurements of the distance to the sun than those previously made by Aristachus (2,000 years earlier) from the geometrical relationships at the exact time of a half-moon.
Wendelen is considered by many as a precursor of Kepler and Newton, and was in fact cited by Newton in his Principia. The crater Vendelinus on the Moon is named after him

Today’s view (Feb 5, 9:34am EST) of the enormous sunspot region 4366, compared with my previous shot (2nd photo, taken Feb 2).
It’s clearly grown since rotating into view — Space.com says it’s now a staggering 15 Earths wide, big enough to see without telescopes or binoculars (though you still need eye protection). And it’s been spitting out powerful M- and X-class flares. Clear skies to all you aurora hunters out there!

Solar activity increases even further with an M6.6 solar flare peaking at 10:02 UTC (Feb 1). The source, AR 4366, is magnetically complex and is now a threat for an isolated X-Flare. Image below by SDO/AIA.High Solar Activity
February 1, 2026 @ 16:50 UTC (UPDATED)
What a difference a few days make on the Sun. Active sunspot region 4366 turned into a firecracker on Sunday with at least fifteen M-Class solar flares and one X-Flare (so far). Despite the brightness of these events, the mechanics have so far failed to launch any noteworthy coronal mass ejections into space and towards our planet. That could change over the next few days as the region continues to develop and currently sports a Beta-Gamma-Delta magnetic configuration. More solar flares including another X-Flare will remain possible.[And today...]
Impulsive X8.1 Solar Flare
February 2, 2026 @ 00:10 UTC
An impulsive X8.1 solar flare was just detected peaking at 23:57 UTC (Feb 1). This is the second strongest flare in terms of peak X-Ray flux of the current solar cycle. Although a bright flare, new imagery suggests that if a CME is associated, it will likely be fairly mild.

We need to shift from the grid as the primary source of electricity, with renewables and batteries as individualized backups, to the other way around.
Being one solar event away from the collapse of our society, individualized sources of electricity can be protected by Faraday cages, with the grid (relieved of strain) serving remote areas and backing up individual solutions in the event of failure.

Strong (G3) #GeomagneticStorm WATCH Valid for 09 Dec 2025
published: Sunday, December 07, 2025 04:42 UTC
A full-halo coronal mass ejection (#CME), associated with an M8.1 flare from Region 4299 at 20:39 UTC on 06 December, is expected to impact Earth early to midday on 09 December, potentially causing periods of G3 (Strong) geomagnetic storming.
Strong Geomagnetic Storm WATCH Valid for 09 December G3
WHAT: A CME is expected to arrive at Earth on 09 December and lead to increased geomagnetic field activity.
EVENT:
A coronal mass ejection (CME) is an eruption of solar material and magnetic fields. When they arrive at Earth, a geomagnetic storm can result. Watches at this level are infrequent, but not uncommon.
EXPECTATION:
A CME is anticipated to arrive at Earth early to midday on 09 December causing elevated geomagnetic field activity, and dependent upon the orientation of the embedded magnetic field, potential exists for G3-Strong storm levels.
EFFECTS:
Limited, minor effects to some technological infrastructure possible, but usually mitigatable. The aurora may become visible over many of the northern states and some of the lower Midwest to Oregon. The general public should consider monitoring our webpage for the latest information and updates.

Record #SolarSuperstorm shrank Earth’s plasma shield 78%, #GPS at risk
Story by Alexander Clark, 12/1/2025
Excerpt: "Why this storm is a warning shot for the #SatelliteEconomy
"Even without a total collapse of the magnetosphere, the recent superstorm delivered a clear warning to the satellite industry. Constellations in low Earth orbit [#LEO], such as #SpaceX’s #Starlink or #OneWeb, already have to contend with atmospheric drag and radiation, but they usually operate well inside the magnetosphere’s protection. When the plasma shield shrinks, those satellites face a double challenge: increased drag from a heated upper atmosphere and a more hostile radiation environment that can degrade electronics and solar panels. The event that compressed Earth’s shield by nearly 80 percent effectively stress-tested the assumptions behind the rapid expansion of commercial space infrastructure, a point underscored in analyses of how a solar storm can threaten satellites when the magnetosphere is squeezed.
"For operators of navigation, communications, and Earth observation satellites in higher orbits, the implications are even more direct. Many of these spacecraft were designed based on historical records of geomagnetic storms that did not include such extreme compression of the magnetosphere, which means their shielding, redundancy, and fault management systems may not fully account for the conditions seen in this event. As I look at the trajectory of the satellite economy, with thousands of new platforms planned for launch in the coming years, the lesson is clear: space weather resilience can no longer be treated as a niche concern. It has to be built into hardware design, constellation architecture, and operational playbooks from the start, or the next superstorm could turn a profitable orbital network into a liability overnight.
"Preparing for the next superstorm in a crowded sky
"The recent compression of Earth’s plasma shield did not trigger the kind of global blackout or navigation collapse that worst-case scenarios envision, but it came close enough to expose the seams in current preparedness. Space weather forecasting has improved, yet the lead times and confidence levels are still limited, especially for the most extreme events. To protect GPS, power grids, and other critical systems, operators need not just alerts that a storm is coming but actionable guidance on how severe the magnetospheric compression is likely to be, which orbits will be most exposed, and how long the elevated risk will last, insights that depend on the kind of multi-satellite observations and modeling showcased in the reconstruction of this storm.
"As I weigh the evidence, the path forward looks less like a single technological fix and more like a layered strategy. That means hardening satellites and ground infrastructure against radiation and induced currents, building redundancy into navigation and timing systems so that GPS is not a single point of failure, and integrating space weather scenarios into everything from grid planning to aviation routing. It also means improving public communication so that when the next superstorm hits, people understand both the seriousness of a 78 percent shrinkage of Earth’s plasma shield and the practical steps being taken to manage the risk. The recent event was a vivid reminder that our digital civilization is built inside a magnetic cocoon that can flex and falter, and that planning for those moments is no longer optional."

'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."

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."

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."

#SolarMaximum could hit us harder and sooner than we thought. How dangerous will the sun's chaotic peak be?
The sun is quickly approaching a major peak in solar activity. Experts warn it could potentially begin by the end of 2023, years before initial predictions suggested.
By Harry Baker, June 23, 2023
"Originally, scientists predicted that the current solar cycle would peak in 2025. But a bumper crop of sunspots, #SolarStorms and rare solar phenomena suggest solar maximum could arrive by the end of this year at the earliest — and several experts told Live Science we are poorly prepared. "
• The sun is becoming more active and may reach peak activity sooner than expected.
• Solar maximum was predicted to happen in 2025, but #sunspot activity has changed that.
• An unusual burst of sunspots this year suggests solar maximum could hit by the end of 2023.
