A solar storm is barreling toward Earth, promising a celestial spectacle that could bring the northern lights to lower latitudes, including New York and Idaho, between the night of March 4 and the early hours of March 5, 2025. Triggered by a coronal mass ejection (CME) from a powerful solar flare on March 1, forecasts suggest the event will graze Earth’s magnetic field, sparking geomagnetic storm conditions rated as G1, with a potential escalation to G2, according to space weather experts. Monitored by NOAA’s Space Weather Prediction Center (SWPC), this phenomenon has aurora enthusiasts on high alert, gearing up to capture the dancing lights in spots far from urban glow. The event ties into an active solar cycle, with the Sun nearing the peak of its 25th 11-year cycle, amplifying solar activity across the board.
The storm’s arrival is anticipated late on March 4, with peak activity expected between 7 p.m. and 10 p.m. EST (9 p.m. to midnight Brasília time), possibly stretching into the early morning of March 5. The strength of the aurora hinges on how charged solar particles interact with Earth’s magnetosphere, potentially pushing visibility beyond typical polar regions. In the United States, northern states like Minnesota and Michigan are primed for viewing, but the chance of sightings in New York and Idaho underscores the event’s potential reach. While Brazil, in the Southern Hemisphere, won’t see the northern lights, the phenomenon piques the interest of local scientists and astronomers tracking global solar effects.
The current solar cycle, which began in 2019, has fueled a surge in CMEs, with over 20 significant events logged since early 2025. These storms don’t just dazzle with auroras—they also influence modern technology, from satellites to power grids. A G1 storm signals mild impacts, but a possible jump to G2 heightens anticipation for a more vivid light show, especially for those in mid-latitude regions of the Northern Hemisphere.
How solar storms create auroras
Charged particles from the March 1 solar flare hurtle toward Earth at millions of kilometers per hour, reaching the planet in about three days. Upon colliding with the magnetosphere, they interact with atmospheric gases like nitrogen and oxygen, producing the northern lights’ vibrant hues—green, red, and purple. This event could hit a Kp index of 5, marking a G1 storm, though physicist Tamitha Skov suggests G2 conditions with a Kp of 6 are in play, expanding visibility southward.
In the U.S., the aurora has previously lit up skies during this solar cycle, with rare sightings in states like Virginia and Missouri in 2024. The storm’s intensity depends on the CME’s magnetic field orientation upon impact, a detail scientists fine-tune in the hours leading up to the event. Dark, rural spots like mountains or parks offer the best viewing odds, particularly between 45 and 55 degrees north latitude.
What to expect from tonight’s aurora
Forecasts pinpoint the strongest geomagnetic activity late on March 4 into early March 5, peaking between 7 p.m. and 10 p.m. EST. NOAA ranks geomagnetic storms on a G-scale from G1 (minor) to G5 (extreme), with this event pegged at G1 but possibly reaching G2. Beyond auroras, minor disruptions to satellite communications and power grid fluctuations could occur, though effects remain limited at these levels.
Observers might see rippling bands or glowing curtains, especially in green—the aurora’s most common shade. In G2 conditions, red and purple hues could emerge, delivering a more striking display. Activity is expected to wane throughout March 5, settling back to normal by March 6 as Earth’s magnetic field stabilizes.
Timeline of the March solar storm
This event fits into a tracked sequence of solar activity in 2025:
- March 1: Solar flare unleashes the CME now heading toward Earth.
- March 4: CME strikes Earth’s magnetic field, kicking off the geomagnetic storm.
- March 5: Peak activity lights up the night, fading by dawn.
This timeline reflects a CME’s typical speed, ranging from 400 to 2,500 kilometers per second, based on the flare’s strength.
Tips for catching the northern lights
Spotting the aurora takes planning and patience. Here are practical pointers for enthusiasts:
- Seek dark locations away from city lights, like national parks or mountains.
- Use cameras with long exposure settings, boosting ISO to 800 or higher for vivid colors.
- Check real-time SWPC updates to tweak plans as storm strength evolves.
- Bundle up—March nights remain chilly at higher latitudes.
These steps boost the odds of witnessing the phenomenon, especially in less aurora-prone areas.
Tech impacts from the solar storm
Geomagnetic storms affect more than just the sky—they touch modern infrastructure. G1 events cause subtle issues, like minor satellite tweaks or slight power grid ripples. G2 conditions might prompt closer monitoring of transformers in northern regions like Canada and Scandinavia to prevent overloads. In 2024, a G3 storm briefly disrupted GPS satellites, highlighting solar effects on daily tech.
Airlines operating polar routes occasionally reroute flights during stronger storms to avoid communication hiccups, though this is uncommon for G1 or G2 events. NOAA tracks these risks live, ensuring critical systems stay safeguarded against major disruptions.
Solar cycle ramps up cosmic events
The 25th solar cycle, peaking mid-2025, drives the uptick in storms like this one. At its height, the Sun boasts more sunspots—hotbeds of magnetic activity sparking flares and CMEs. Records show geomagnetic storms doubled since the 2019 solar minimum, with around 15 G1-or-higher events in 2024 alone. This trend is set to persist into 2026 as the cycle winds down.
For astronomers, the March storm offers a chance to study Sun-Earth dynamics, sharpening predictive models. Meanwhile, casual skywatchers in the Northern Hemisphere ready themselves for a rare aurora glimpse, blending science with nature’s awe.
Aurora thrills and rallies enthusiasts
The prospect of northern lights in mid-latitudes like New York has sparked excitement among photographers and night-sky fans. Past events have drawn crowds to spots like Bear Mountain, New York, where green and red ribbons painted the sky. Tonight’s forecast reignites that buzz, with online communities sharing maps and timing tips to optimize the experience.
In Brazil, the northern lights won’t appear due to its Southern Hemisphere position, but the event stirs scientific curiosity. The Southern Hemisphere counterpart, the aurora australis, shines in places like Antarctica, though current solar conditions favor the north. This March storm underscores how cosmic events link the planet, delivering a fleeting moment of wonder in an interconnected world.
