    "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."

  2. Solar Storm?

    The risk of solar storms for humans living on the Moon is much greater than for those safely living on Earth under Earth’s protective magnetic field.

    🌍 SOLAR STORM RISK ANALYSIS: A FUTURIST ASSESSMENT

    1. VIDEO RECAP

    Core Thesis: NASA Goddard research reveals Earth’s magnetosphere has no saturation safety valve—geomagnetic response scales linearly with solar storm intensity, making Carrington-class events potentially catastrophic for modern civilization. The apparent flattening in historical data was a statistical illusion caused by measurement noise and propagation delays between L1 and Earth.

    Key Findings:

    • The Myth of Saturation: Historical storms appeared to flatten because satellites at 1.5 million km (L1) measured delayed, noisy plasma evolution. Correcting for this bias reveals a strictly linear response—no natural upper bound exists.
    • LEO Threat: Mega-constellations face simultaneous threats: atmospheric drag burning up fuel budgets, electronic failure from induced currents, and cascading Kessler Syndrome debris collisions that could lock humanity out of space for decades.
    • Ground Infrastructure: Geomagnetically Induced Currents (GICs) can saturate transformers, causing multi-month blackouts. Lloyd’s estimates: $600B–$2.6T in damages, 20M–40M without power for weeks to years.
    • Action Plan: Install ~$4B worth of capacitive neutral-blocking devices on critical US transformers; enforce international regulations limiting LEO satellite density and mandating automated collision avoidance, radiation hardening, and rapid de-orbit during solar alerts.

    2. RESEARCH REPORTS: PROBABILITY & DANGERS

    Probability Estimates for Extreme Events

    SourceMetricProbability (10-year window)NotesRiley (2012)Dst ≤ −850 nT~12%Based on power-law distribution extrapolation from 46 years of dataSiscoe et al. (2006)Dst ≤ −850 nT~3–7%Conservative estimate using multiple proxiesMoriña & Swanson (2019)Carrington-class event0.92%Weibull distribution model, much more conservative; accounts for decreasing hazard rate over timeItu (2024)Carrington-level1–25%Wide range reflecting uncertainty in solar cycle activity projections

    Critical Uncertainty: Solar cycle maximum duration is projected to last only 15–36 more years (Abreu et al. 2008). If a grand minimum follows, CME frequency drops but galactic cosmic ray exposure increases—posing elevated risks for astronauts and aviation crews.

    Dangers by Domain

    • Power Grids: GICs cause transformer saturation and physical damage; replacements take months/years to produce. Quebec 1989 outage: 6M people affected, $27M damages.
    • Satellites & Communications: CME impacts damage electronics; undersea cables may be fried by induced currents; GPS navigation could fail globally during extreme events.
    • Aviation: Polar flight paths face communication disruption and radiation exposure; extreme storms could force transpolar reroutes or groundings.
    • Astronauts: Beyond Earth’s magnetosphere, astronauts face acute radiation sickness from solar proton events (SPEs) and long-term cancer risks from galactic cosmic rays during solar minima.

    3. WHY IGNORING RISKS ENDANGERS LIVES & LIVELIHOODS

    The Multiplier Effect: Modern civilization is hyper-dependent on interconnected infrastructure—power grids, digital networks, supply chains, financial systems. A Carrington-level event doesn’t just cause isolated blackouts; it creates systemic cascades:

    • Power loss → water pumps fail → food/water shortages
    • GPS disruption → aviation groundings, logistics collapse, timing system failures across banking and energy markets
    • Satellite comms failure → emergency coordination paralysis during secondary disasters

    Temporal Scale of Destruction: Unlike hurricanes (days), geomagnetic damage can persist for weeks to months. During winter, this translates to potential mass fatalities from cold exposure. Recovery costs—transformer replacements alone in the US would take 20+ years to complete based on current production capacity.

    The Asymmetric Risk Profile: Solar storms are global, but impacts are regional (amplified near poles). However, financial systems and digital infrastructure are truly global. A blackout in a major corridor like Washington-D.C./New York affects international trade, financial markets, and supply chains worldwide. Unlike localized disasters, there is no geographic escape route from systemic collapse.

    4. ADVANCED AI SCIENTIST OPINION: FUTURIST PERSPECTIVE

    Assessment: The risk is non-zero but low-probability/high-impact—the classic “black swan” scenario that demands asymmetric preparation due to irreversible consequences.

    Strategic Recommendations:

    1. Infrastructure Hardening is Non-Negotiable: Capacitive neutral blocking devices are a one-time investment with high ROI. If we assume 12% probability over a decade, and damages exceed $600B, the expected value of inaction vastly exceeds mitigation costs (~$4B). This is basic risk economics.
    2. Space Stewardship Over Prevention: Rather than banning LEO mega-constellations, implement science-based density limits with mandatory collision avoidance systems, radiation-hardened components, and rapid de-orbit capabilities during solar alerts. The goal isn’t to remove space infrastructure but to make it resilient.
    3. Predictive Capabilities: Space weather forecasting is ~50 years behind terrestrial forecasting. Investing in L1 Lagrange point monitoring (SWFO-L1) and Parker Solar Probe data utilization will be critical for early warning. A 24–72 hour warning window could allow grid operators to load batteries, reroute traffic, and protect sensitive infrastructure.
    4. The Paradox of Solar Activity: An active solar cycle protects astronauts from galactic cosmic rays (the “sunny side”), but increases CME risk. Future Mars missions should be scheduled during solar maximum—counterintuitive but scientifically sound. For Earth dwellers, the net benefit is minimal compared to risks.
    5. Policy Must Be Proactive, Not Reactive: Current grid hardening efforts target moderate storms (1989 event class), not Carrington-scale events. Regulatory frameworks need to mandate GIC-resistant transformer designs and real-time monitoring networks at scale.

    Final Judgment: The risk is small but existential. We should treat it like nuclear safety: not with panic, but with rigorous engineering standards, continuous preparedness, and international coordination. The alternative—waiting for the next Carrington event to force reactive measures—is profoundly irrational from both an economic and humanitarian standpoint.

  4. Could a powerful geomagnetic storm be the reason 8,000 Victorian homes suddenly lost power in January this year?

    I had a chat with Dr Richard Marshall from Australian Bureau of Meteorology Space Weather about the origin of solar storms and the risks they present to our communities and critical infrastructure.

    So great to be able to have such fantastic and professional insights about these important events and how we, as a society, need to mitigate against them.

  5. [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."
