The sun is currently throwing a massive, multimillion-degree tantrum.
If you've noticed your GPS acting a bit wonky lately or your satellite internet dropping out during a perfectly clear day, you aren't imagining things. We are officially in the thick of Solar Cycle 25, and it's turning out to be way more intense than the experts at NASA and NOAA originally predicted back in 2019. Honestly, the sun doesn't care about our 5G rollout plans or our reliance on orbital infrastructure.
It's just doing what it does every 11 years or so. But this time, the stakes are higher because we've never been more tethered to the "cloud," which, as it turns out, is highly susceptible to literal space weather.
The 2026 Solar Maximum: What’s Actually Happening?
Basically, the sun goes through these regular heartbeats. During a solar maximum, the sun’s magnetic poles flip. It’s messy. Imagine a giant ball of plasma where the magnetic field lines are getting twisted and tangled like a bin of old charging cables. When those lines snap and reconnect, they launch massive bursts of energy into space.
We call these Coronal Mass Ejections (CMEs) and solar flares.
A solar flare is like a flashbulb—it hits us in eight minutes. A CME is more like a physical cloud of magnetized particles traveling at millions of miles per hour. When that cloud slams into Earth’s magnetic field, it creates a geomagnetic storm. In 1859, the "Carrington Event" was so powerful it made telegraph wires burst into flames. If that happened today? We’d be looking at trillions of dollars in damage.
While we haven't seen a Carrington-level event yet in 2026, we have seen a massive uptick in G4-class storms. These aren't just for pretty auroras in places they don't belong; they are actively degrading the lifespan of low-Earth orbit satellites.
Why the 2026 peak is different from 2014
The last solar maximum peaked around 2014, but it was a bit of a dud. It was one of the weakest cycles on record. Because of that, a lot of the tech we built over the last decade hasn't really been "battle-tested" against a truly angry sun. Since then, we've launched thousands of Starlink satellites. We've moved our entire financial system to the cloud. We've started relying on GPS for everything from autonomous tractors to food delivery drones.
Dr. Tamitha Skov, a well-known space weather physicist, has been vocal about how our modern "just-in-time" society is uniquely vulnerable to these fluctuations. It's not just about power grids anymore. It's about the subtle data corruption that happens when high-energy protons zip through a microchip in a data center.
Your Phone, Your Car, and the Ionosphere
You've probably used GPS today. Most of us do. But GPS isn't a "set it and forget it" system. It relies on timing signals sent from satellites about 12,000 miles up. Those signals have to pass through the ionosphere—the layer of Earth’s atmosphere that gets "puffed up" by solar radiation.
During the 2026 Solar Maximum, the ionosphere becomes turbulent.

Think of it like trying to look at a coin at the bottom of a swimming pool while someone is doing cannonballs. The signal gets refracted. This leads to "GPS scintillation." For a casual user, it might mean your Blue Dot is 50 feet off. For a maritime vessel navigating a narrow channel or an automated drilling rig, 50 feet is a catastrophe.
The Starlink Factor
SpaceX actually lost about 40 satellites in a single go back in early 2022 because of a minor geomagnetic storm. The storm increased the density of the upper atmosphere, creating "drag." The satellites basically hit a wall of air and couldn't stay in orbit.
Since then, satellite operators have had to become amateur meteorologists. In 2026, we are seeing operators burning through their fuel reserves much faster just to keep their birds at the right altitude. This means satellites that were supposed to last 10 years might only last seven. That’s a massive financial hit for the telecommunications industry that eventually trickles down to your monthly bill.
It’s Not Just Satellites; It’s the Ground Too
Ground-induced currents (GICs) are the boogeyman of the power industry. When the Earth's magnetic field shakes, it induces electricity in long metal structures. Power lines are perfect antennas for this.
In 1989, the entire province of Quebec went dark in seconds because of a solar storm. The grid literally melted in some places.
Today, utility companies use "geomagnetically induced current" sensors to monitor these flows. If things get too hairy, they actually have to intentionally throttle the grid or shut down certain transformers to prevent a total blowout. It’s a delicate balancing act. You might experience "brownouts" or "voltage sags" during high solar activity periods in 2026 that have nothing to do with the local weather and everything to do with a sunspot 93 million miles away.
The "Internet Apocalypse" Myth vs. Reality
You might have seen clickbait headlines about an "internet apocalypse." Let's walk that back a bit. The fiber optic cables that carry most of the world's data don't carry electricity, so they aren't affected by magnetic storms.
However.
The repeaters—the signal boosters spaced out every 50 to 100 kilometers along under-sea cables—are powered by electricity. If a massive storm hits and fries the power units for those undersea cables, the internet doesn't "die," but the connections between continents could go dark for weeks or months. Repairing a cable at the bottom of the Atlantic isn't a quick fix.
Professor Sangeetha Abdu Jyothi from the University of California, Irvine, published a famous paper on this. She pointed out that while our local infrastructure is robust, our long-haul global connections are the Achilles' heel. In 2026, we are seeing more "packet loss" on these international routes during peak solar activity. It's subtle, but it's there.
High-Altitude Flights and Radiation
If you’re a frequent flyer, particularly on polar routes (like New York to Hong Kong), the 2026 Solar Maximum is something your airline is watching closely.

When the sun is active, it's not just magnetic fields; it's radiation. At 35,000 feet, there’s less atmosphere to protect you. During a major solar particle event, pilots often have to fly at lower altitudes to use the atmosphere as a shield. This burns more fuel and causes delays.
Is it dangerous? Not for a one-off flight. But for flight crews who spend 80 hours a month in the air, the cumulative dose of radiation during a solar max can actually exceed what nuclear power plant workers are allowed to receive. Some airlines have started rerouting flights away from the poles entirely during G5-level storms to avoid both radiation and the total loss of high-frequency (HF) radio communication.
How to Protect Your Own Tech
Look, you don't need to wrap your house in tinfoil. But there are a few practical things that actually make sense during a solar peak year.
First, stop relying solely on cloud-based maps if you’re heading into the wilderness. If a solar storm knocks out the local GPS correction network, your phone's accuracy will tank. Download offline maps and maybe—heaven forbid—carry a physical compass.
Second, high-quality surge protectors are non-negotiable. While a solar storm won't necessarily "blow up" your toaster, the voltage fluctuations on the grid can wear out the sensitive power supplies in your high-end PC or OLED TV.
Lastly, if you're a drone pilot or a boat owner, pay attention to the "Kp-index." You can find this on apps like SpaceWeatherLive. If the Kp-index is 7 or higher, just stay home. Your drone's "Return to Home" feature might decide "Home" is actually three miles away in a lake because its GPS fix is garbage.
What’s Next for Solar Cycle 25?
We haven't reached the absolute peak yet. The current trajectory suggests the maximum will plateau through the end of 2026 and into early 2027. We are likely to see more "cannibal CMEs"—where one solar blast overtakes another, combining into a super-powered wall of plasma.
The good news is that our detection systems are better than ever. The DSCOVR satellite sits between us and the sun, giving us a 15-to-60-minute heads-up before a storm hits. It’s not a lot of time, but it’s enough for grid operators to stabilize and for astronauts on the ISS to move to shielded modules.
Actionable Steps for the Rest of 2026
- Check the Kp-Index: Before doing any precision work with GPS or drones, check the current geomagnetic activity. A Kp of 0-4 is normal. 5 is a minor storm. 7+ means things are getting weird.
- Hardware Resilience: Use an Uninterruptible Power Supply (UPS) for your most expensive electronics. It cleans the "dirty" power that often precedes a grid-level surge.
- Data Redundancy: Keep physical or local backups of critical data. Relying 100% on a satellite-linked cloud service during a solar max is just asking for a sync error.
- Aviation Awareness: If you're a pilot or high-frequency radio hobbyist, expect "dead zones" in the 3-30 MHz range. Don't assume your equipment is broken; it's just the atmosphere being stubborn.
- Watch the Auroras: On a lighter note, this is the best year in a decade to see the Northern or Southern Lights. They’ve been spotted as far south as Arizona and Italy recently. If a big storm is forecasted, get away from city lights and look up.
The sun is a dynamic, violent star, and we just happen to live right next to it. We’ve built a world that assumes the sun is a static lightbulb, but 2026 is proving that’s a dangerous assumption. By understanding the cycles, we can at least avoid being surprised when the Wi-Fi gets wonky.
