"A Solar Superstorm Caused a GPS Glitch Bad Enough to Crash Self-Driving Cars
The massive eruption threw GPS readings off by more than 33 feet (10 meters).
On November 11, 2025, the Sun unleashed a series of solar flares that struck Earth, triggering a severe geomagnetic storm that peaked for around six hours. The event triggered beautiful auroras across the skies, but it also wreaked havoc on crucial technology we rely on for our daily lives.
In a new study published in the journal Geophysical Research Letters, a team of scientists measured the disruption to global navigation systems caused by the geomagnetic storm. The results revealed significant positioning errors, large enough to mess with precision agriculture and autonomous vehicles across the U.S."

Ancient #SolarStorm smashed Earth at wrong part of the sun's cycle — and scientists are concerned
The 9,200-year-old storm left researchers with a stark conclusion: We are not ready for the next one.
By Brandon Specktor
published January 28, 2022"An extremely powerful solar storm pummeled our planet 9,200 years ago, leaving permanent scars on the #ice buried deep below #Greenland and #Antarctica.
"A new study of those ancient ice samples has found that this previously unknown storm is one of the strongest outbursts of solar weather ever detected and would have crippled modern communications systems if it had hit Earth today.
"But perhaps most surprising, the massive storm appears to have hit during a #SolarMinimum, the point during the sun's 11-year cycle when solar outbursts are typically much less common, according to the study, published Jan. 11 in the journal Nature Communications. Because of this unexpected discovery, the study researchers are concerned that devastating solar storms could hit when we least expect them — and that Earth might not be prepared when the next big one arrives.
"Solar storms occur when magnetic field lines on the sun's corona (the outermost part of the sun's atmosphere) become tangled up and then violently snap back into place. This sudden magnetic reconnection can release huge gouts of plasma and magnetic field known as coronal mass ejections (CMEs), which surf across space on the sun's ever-gusting #SolarWind.
"If a powerful #CME passes over Earth, it can compress the planet's #MagneticShield, causing what's known as a #GeomagneticStorm.
"Mild geomagnetic storms can damage #satellites and interrupt radio transmissions; severe storms, like the 'Halloween storms' of 2003, can cause widespread #PowerOutages across the world and permanently damage #ElectricalInfrastructure, such as power transformers. Some researchers fear that a sufficiently large solar storm could also ravage the world's undersea internet cables, resulting in an '#InternetApocalypse' that leaves huge chunks of the world population disconnected for months.
"CME outbursts typically peak every 11 years or so, when the sun enters the part of its natural activity cycle known as the solar maximum — the time when magnetic activity in the corona is in high gear.
"Today, satellites can monitor solar outbursts directly. But finding evidence of ancient storms requires some atomic detective work. The authors of the new study looked for evidence of special particles known as #CosmogenicRadionuclides — essentially, radioactive isotopes (versions of elements) created when charged solar particles collide with elements in Earth's atmosphere.
"These radioactive particles can appear in natural records, like tree rings and ice cores. In the study, the authors looked at the latter, analyzing several cores drilled in Antarctica and Greenland. Cores from both locations showed a remarkable spike in the radionuclides beryllium-10 and chlorine-36 around 9,200 years ago, indicating that a powerful solar storm swept across Earth at that time.
"Further analysis of the cores showed that the storm was particularly powerful — perhaps on a par with the most powerful solar storm ever detected, which occurred during a solar maximum between the years 775 B.C. and 774 B.C.
"The newly discovered storm's occurrence during a solar minimum, when magnetic activity on the sun should be low, left the study authors puzzled and alarmed.
"'This [storm] further pushes the magnitude of a potential worst-case scenario for [solar storm] events,' the researchers wrote in the study.
"According to the study authors, it is now essential for researchers to detect more ancient, extreme storms in the ice-core and tree-ring records, to determine if there is some sort of pattern beyond the sun's 11-year cycle that dictates when the most extreme storms will occur."

A massive solar storm hit the Earth 14,300 years ago, leaving traces in tree rings. The storm was 10 times stronger than any recorded in modern history and could have caused widespread auroras and geomagnetic disturbances. The storm could also provide clues to the origin and frequency of such events, which could threaten modern technology. #SolarStorm #TreeRings #History https://timesofindia.indiatimes.com/home/science/solar-storm-earth-tree-rings-apocolypse-impact-of-solar-storms/articleshow/104283176.cms

#SolarHam Updates:
Minor Radiation Storm Continues
March 14, 2023 @ 18:50 UTCProton levels remain at the minor (S1) radiation storm threshold a full 36 hours following a major coronal mass ejection (CME) on the farside of the Sun. We can use common sense to understand that had the full halo CME estimated to be traveling at least 3000 km/s been Earth directed, we would be talking about a significant radiation storm and more than likely, a severe geomagnetic storm. Earth dodged a solar storm this time around, however the next several years will see more opportunities for major events as we head towards solar maximum."

#Spaceweather news:
"EXTREMELY RARE' FARSIDE CME: Something big just happened on the farside of the sun. During the early hours of March 13th, SOHO coronagraphs recorded a farside halo CME leaving the sun faster than 3000 km/s.
"MINOR GEOMAGNETIC STORM WATCH: Minor G1-class geomagnetic storms are possible on March 15th and 16th in response to a number of incoming CMEs. NOAA forecasters believe that 2 or 3 glancing blows are possible, individually weak but collectively effective.
"FARSIDE SUNSPOTS: The source of yesterday's farside CME (described below) is a mystery, but there are two leading suspects. Helioseismic maps reveal a pair of large active regions on the far side of the sun.
"Both will rotate around to the Earthside of the sun within a week, potentially bringing potent sunspots into our planet's 'strike zone.' In the meantime we will keep an eye out for CMEs flying over the edge of the sun, indicating additional farside activity.
"Because of its extreme speed, this CME is classified as 'extremely rare,' a fast-mover that occurs only once every decade or so. A NASA model of the event shows the CME heading almost directly away from Earth. Good thing!
"Although the CME was not Earth-directed, it has nevertheless touched our planet.
"NOAA's GOES-16 satellite has detected the particles reaching Earth--all from the CME's backside. Imagine what a frontside blast would have been like. Earth's magnetic field is funneling the particles toward the poles where a type of radio blackout is underway--a polar cap absorption (PCA) event.
"Airplanes flying over these regions may find that their shortwave radios won't work due to the ionizing effect of infalling protons. This PCA could persist for a day or more."
