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.

"Transpower has issued a grid emergency notice ahead of a severe geomagnetic storm and removed some South Island electricity transmission lines from service.
The national grid operator says the move won't affect the electricity supply to homes and businesses, but will prevent damage to critical equipment if the storm worsens.
Geomagnetic storms can send unwanted currents through electricity circuits, and have the potential to cause serious damage if they reach substations transformers or large hydroelectric dams.
The storms are caused by space weather, when the Sun ejects plasma and other matter in Earth's direction.
Coronal mass ejections (CME) are rare, and generally aren't noticed on earth thanks to the planet's magnetic field shielding the planet from particles, Transpower said."

NASA’S Parker Probe is on a mission to “touch the sun.” It’s orbiting, with each trip around a bit closer than the previous.
Parker has a camera system called WISPR that films the sun’s corona. It just recently sent back stunning images of the closest images of its atmosphere.

Aurora Australis from Royal National Park! This is AMAZING.
The big solar storm that is passing us this week, triggered nu a coronal mass ejection from the Sun has produced a class G4 / G5 geomagnetic storm.
Our magnetosphere deflects most of the particles from Sun away, but near the poles, some spiral down and excite our atmosphere - producing aurora.
This storm was powerful enough to generate aurora sightings as far north as Coonabarabran and the Siding Spring Observatory. That's around 340 km NW of Sydney (closer to the equator, at 31 degrees south!)
While city lights drowned out the view for many, those under darker skies were treated to an extraordinary show. This stunning timelapse footage, captured by my friend Filippo Rivetti from Royal National Park south of Sydney, offers a glimpse of the awe-inspiring beauty and planetary-scale force of this event.
A reminder of the vast, dynamic forces at play: a star lashing out across space, and a planet, our home planet with its protective magnetic shield - hosting the only life we know of so far in the Universe, safely within.

#SpaceWeather update via #SolarHam
"So is old region #AR3664 still active? Of course it is!
"An X2.9 solar flare was observed around the returning region at 07:08 UTC (May 27, 2024). The event is also responsible for an energetic coronal mass ejection (#CME) now emerging in updated coronagraph imagery. Because the sunspot region is still located behind the east limb, the flare itself was likely stronger than the X2.9 measurement. The CME itself should be directed away from our planet. We may see some busy days ahead of us. Stay tuned!"

Estimated X12 #SolarFlare from [presumed] #AR3664, which is on the far side of the Sun right now.
#CarringtonEvent was believed to be X45.
#AR3664 will be Earth-facing again soon.
"A fast moving, full halo coronal mass ejection (CME) is seen leaving the Sun this morning beginning around 05:30 UTC (May 20). Based on updated imagery, this event occurred on the farside of the Sun and is not Earth directed. Perhaps our old friend AR 3664 is up to its old tricks again. We should begin to see the big sunspot region turn back into view early next week."

[May be behind a paywall] The Strongest #SolarStorm in 20 Years Did Little Damage, but Worse #SpaceWeather Is Coming
Years of careful planning helped safeguard against last weekend’s severe space weather, but we still don’t know how we’d cope with a monster event
By Jonathan O'Callaghan & Lee Billings
May 16, 2024"For years, we have been warned about impending doom from the sun. If pointed in our direction, powerful eruptions of radiation and plasma from our star can strike our planet to supercharge Earth’s atmosphere and magnetic field, effectively hitting a global 'reset' button on much of our #ModernTechnology. A sufficiently intense bombardment could raise a #Geomagneticstorm that would push satellites out of orbit, short out submarine cables that suture together the #Internet and plunge the world into darkness with massive #blackouts from collapsed #PowerGrids. Yet this past weekend, when one of the strongest solar outbursts in 20 years blasted our planet, we managed to emerge unscathed thanks to years of careful public and private planning.
"The storm has ebbed, although the solar region that sparked it has since spat out additional monstrous flares—fortunately no longer targeted at Earth because of the sun’s spin [which will change in a short time, as that spot will once again be Earth-facing]. But while we’ve passed our biggest test yet, experts say now is not the time to let down our guard: the question of more cataclysmic solar activity isn’t a matter of 'if' but 'when.'
"'This is a success story,' says Shawn Dahl, a space weather forecaster at the National Oceanic and Atmospheric Administration’s [#NOAA] Space Weather Prediction Center (#SWPC) in Boulder, Colo., but the weekend’s storm was 'nowhere close' to the strength of more powerful known historical events. Is it time to put our feet up? 'Heck no,' he says.
"On May 8, after ground- and space-based telescopes detected multiple explosive outbursts from the sun headed for Earth, the SWPC issued a warning of an imminent severe space weather event. At least seven of these outbursts, known as coronal mass ejections, or #CMEs, walloped our planet with billions of tons of solar plasma—an interplanetary punch that left Earth’s magnetic field ringing and made the upper atmosphere swell, almost as if bruised. The resulting geomagnetic storm was the most severe since 2003. It posed potentially grave dangers to global infrastructure while also bathing much of the world in achingly beautiful #auroral displays.
"At present, it’s difficult to say just how close we came to catastrophe because many companies— from grid controllers to satellite operators—do not like to reveal information on how a geomagnetic storm affected them, says Daniel Welling, a climate and space scientist at the University of Michigan. "'They don’t want to look like they’re vulnerable,' he says. 'Satellite operators have to insure their spacecraft, and that can be very expensive.' Yet various scattered reports are already offering some insight into the storm’s disruptive effects. Flight trackers showed airlines rerouting planes to avoid Earth’s poles, where crews and passengers would have been exposed to worrisome spikes in #CosmicRadiation from the storm. Transpower, New Zealand’s state-owned enterprise running that nation’s electric power, said in a statement that it had preemptively 'switched off some circuits across the country on Saturday [May 11],' and as a result, there was 'no impact on New Zealand’s electricity supply.' In Minnesota, the firm Minnesota Power opened capacitor banks to deal with possible effects from the storm. Similar precautions were likely taken at other power grids around the world, too, although the lack of information makes it 'tremendously' difficult to know how effective those measures were, Welling says.
"Geomagnetic storms can also play havoc with signals from #GPS satellites, and multiple farmers reported issues with GPS-guided farming equipment over the weekend. In South Dakota, one farmer’s tractor started #DrivingInCircles during the storm, and multiple farmers reported outages on social media. 'Our GPS on both the planter and the strip tiller were absolutely bonkers today,' one commenter wrote on Reddit. 'I saw this post and looked ... no GPS,' said another. LandMark Implement, a John Deere dealership based in Nebraska and Kansas, texted its customers an advisory to 'turn off' GPS devices on their farming equipment. 'The base stations were sending out corrections that have been affected by the geomagnetic storm and were causing drastic shifts in the field,' the company noted in an online post. LandMark declined to comment further when contacted.
"The storm posed hazards in space as well. Seven astronauts on the International Space Station were mostly safe from the storm’s effects, #NASA said, but did have to take some precautions. 'The crew was told to avoid lower-shielded areas of the space station out of an abundance of caution,' says Sandra Jones, a spokesperson for NASA’s Johnson Space Center. 'Certain areas provide less protection from radiation, such as the air lock, while other areas, such as crew quarters, provide enhanced protection. The crew was never in any danger, and the energy levels have since decreased.' Other satellite operators experienced greater difficulties. One company in the U.K., Sen, which streams 4K video from a satellite in low-Earth orbit, chose to power down its spacecraft for four days to prevent any damage from the storm, such as fried circuit boards or electronic failures. 'It was in an idle mode,' says Marcin Bujar, spacecraft operations lead at Sen. 'We just kept the bare minimum on—the flight computer and radio receiver.' This prevented the satellite from carrying out some tasks, including planned observations of flooding in South America and wildfires in Canada. 'It definitely had an impact,' Bujar says."

Interesting article. though McDowell's “The sun is a powerful enemy” is a strange way to express our predicament.
human systems may be both dependent on—and vulnerable to— all that the sun has to give...
but the real adversaries are right here - extractive industrialisation & agriculture, cutting down the forests, burning all the fossil fuel...

#SolarHam #Spaceweather Update:
Largest #SolarFlare Of #SolarCycle25 Observed
May 14, 2024 @ 17:05 UTC (UPDATED)
"The largest solar flare of the current solar cycle 25, and largest since 2017 was just observed around deparing #AR3664 off the west limb. The #X8.7 event peaked at 16:51 UTC (May 14) causing a strong R3 level radio blackout directly over North America. More to follow.
"And Then...
"An eruption in the vicinity of newly assigned #AR3682 measuring M4.4 was observed at 17:38 UTC (May 14). This event looks to be eruptive, meaning a #CME will be produced.

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."

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."

Enormous '#Sunspot archipelago' 15 times wider than Earth could soon bombard us with #SolarFlares
Story by Harry Baker, November 21, 2023
"One of the largest and most densely populated sunspot regions seen in more than a decade has appeared on the sun's nearside to Earth — and has begun to unleash a barrage of solar storms that are shaking up our home star's surface in a big way. The sunspots' emergence could make it an interesting few weeks for Earth, which will soon be in the firing line of these eruptive dark patches.
"The first sunspot group, named #AR3490, rotated onto the sun's nearside on Nov. 18 over the star's northeastern shoulder. The dark patch was quickly followed by another sunspot group, #AR3491, which trailed in its wake, #Spaceweather.com reported.
"Scientists already knew that the sunspot groups were on their way because they had been tracking '#HelioseismicTremors," or ripples in the sun's surface, from the area. The sunspot region is 'so large, it is affecting the way the whole sun vibrates,' Spaceweather.com representatives wrote.
"Since emerging, the sunspot groups have split up and birthed new dark patches, including #AR3492, #AR3495, #AR3496 and #AR3497, which has created a 'solar archipelago of sunspots,' astronomy news site EarthSky reported.
"In total, the massive collection of sunspots spans around 125,000 miles (200,000 kilometers) across, which is more than 15 times wider than Earth, according to Spaceweather.com.
"The sunspots have already spat out at least 16 C-class and 3 M-class solar flares — which are the third and second strongest flare classes, respectively — in the last 4 days, according to SpaceWeatherLive.com. And experts are warning that there could be many more of these flares in the next few weeks, as well as potentially #XClass flares, the strongest type of solar flare.
"The impending flares may also birth coronal mass ejections (#CMEs), or enormous blobs of charged solar particles, that could slam into Earth and trigger strong geomagnetic storms, which could cause radio blackouts and spark vibrant aurora displays.
"Astronomers have also spotted several large loops of plasma, known as #SolarProminences, growing above some of the sunspots in the group. The largest loops tower more than 40,000 miles (64,000 km) above the surface, according to EarthSky, and could snap off and fling into space at any moment, temporarily leaving behind enormous 'canyons of fire' in the sun's surface.
"At least three sunspot groups have also emerged on the sun's southern hemisphere in the last few days.
"The sunspots' emergence is the latest sign that the sun is fast approaching the explosive peak in its roughly 11-year solar cycle, known as the solar maximum, which scientists now predict will begin next year.
"During solar maximum, sunspots become much more frequent and increase in size as the sun's magnetic fields get tangled up, allowing the dark patches to grow more easily.
"The latest dark patches make up 'probably the biggest sunspot region I've seen so far from [the current] solar cycle,' Chris Wicklund, a meteorologist and aurora photographer, wrote on X (formerly known as Twitter). 'The next 14 days could be very interesting,' he added."

@ai6yr @harkank @melanie So, the phenomenon I was thinking of is "multiple #CMEs" or #CannibalCMEs" -- where they combine together...
From December, 2023: "A new NOAA model shows three CMEs combining to form a single storm front, striking in unison on Dec. 16th around 20:00 UT.
All of the incoming CMEs were launched into space by sunspot AR3514, which has been flaring almost constantly since Dec. 13th. The most important CME is linked to the X2.8-class flare of Dec. 14th; that one alone should be sufficient to spark a geomagnetic storm this weekend." -
#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."

Estimated X12 #SolarFlare from [presumed] #AR3664, which is on the far side of the Sun right now.
#CarringtonEvent was believed to be X45.
#AR3664 will be Earth-facing again soon.
"A fast moving, full halo coronal mass ejection (CME) is seen leaving the Sun this morning beginning around 05:30 UTC (May 20). Based on updated imagery, this event occurred on the farside of the Sun and is not Earth directed. Perhaps our old friend AR 3664 is up to its old tricks again. We should begin to see the big sunspot region turn back into view early next week."
