"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."

Como proyecto de fin de semana, convertí el RTL-SDR en un Poor Man's eCallisto (por los radiotelescopios de esa red), con una antena de handy y un cable usb de 5m. Lo voy a dejar tomando datos a ver si puedo detectar llamaradas solares en radio, está difícil, pero si detecta algo me tiro a hacer una antena mejor, una logarítmica o algo así #radio #telescopio #solar #rtlsdr #hamradio #solarburst #ecallisto #solaractivity #actividadsolar #solarstorm #tormentasolar

[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."

Bueno, en el Sol acaba de ocurrir una erupción solar clase X8.7 hace apenas un rato, siguiendo otras dos flares clase X1.7 y X1.2, la alerta por correo de esta última no ha llegado aún. Estos eventos fueron detectados por el radiotelescopio e-callisto del OALM y han ocasionado un type II y type III radio burst que son básicamente, señales de radio intensas, generadas por la aceleración por onda de choque de los electrones en la corona solar, que muchas veces acompañan las eyecciones de masa coronal o CMEs . El proyecto e-Callisto es una red internacional de estaciones terrenas con radiotelescopios de bajo costo que observan la actividad solar las 24hs distribuidos por todas partes del mundo entre 45 y 870MHz y que buscan detectar estos bursts o explosiones en radio. Esto ayuda a caracterizar la la actividad solar y en casos de eyecciónes de masa coronal, ayudar a determinar la velocidad de las partículas que vienen hacia la Tierra.
