GOES satellites measured an M1.4-class solar flare that peaked on September 2, 2026, at 19:11 UTC. The flare registered an X-ray flux of 1.4e-5 watts per square meter, which puts it at the low end of the ‘M’ (medium) category on the solar flare scale. On NOAA’s radio blackout scale, this corresponds to roughly an R1 event — the weakest of the five levels.
What this means for you
For most people, the answer is simple: nothing noticeable. An R1-level flare can cause brief, minor degradation of high-frequency (shortwave) radio signals on the sunlit side of Earth at the moment of the flare. That mainly affects ham radio operators, aviation and maritime communications that rely on shortwave, and some emergency backup radio systems — not cell phones, Wi-Fi, or broadcast TV.
Power grids, satellites, and everyday electronics are not at risk from an M1.4 flare alone. Flares of this size are common, with the Sun often producing several per week during active periods.
The one item genuinely worth watching: if this flare launched a coronal mass ejection (CME) — a burst of solar material — toward Earth, that material could arrive in one to three days and potentially trigger a geomagnetic storm. Even then, storms associated with M-class flares are typically minor, occasionally producing auroras at high latitudes and requiring grid operators to take routine precautions.
Practical pointers: (1) If you rely on shortwave radio for emergency communications, know that brief signal fade today on the daylit side of Earth was expected and temporary. (2) Watch the Kp index over the next 48–72 hours — a rising Kp would signal an arriving CME and a chance of auroras. (3) No special action is needed for your home, devices, or vehicle; standard preparedness kits already cover anything a minor geomagnetic storm could realistically cause.

Frequently Asked Questions
Will this flare affect my power, internet, or cell phone?
No. An M1.4 flare is a medium-strength, routine event and cannot disrupt household power, internet, or cellular service on its own.
Could a geomagnetic storm still follow this?
Possibly — if the flare launched a CME toward Earth, it could arrive in 1–3 days and cause a minor geomagnetic storm, which NOAA would flag in advance. Storms from M-class flares are usually weak and manageable.
I heard there were radio blackouts — is that dangerous?
The R1-level blackout from this flare is brief and only affects high-frequency shortwave radio on Earth's sunlit side. It is a known, expected effect and poses no danger to people.
Will I be able to see the Northern Lights from this?
Not from the flare itself, but if a CME arrives in the next few days, high-latitude regions could see auroras. Check the Kp index — a reading of 5 or higher means auroras are possible at northern latitudes.
