Northern Lights erupt in good Aurora sky over Northern Minnesota Little Sand Lake in Remergetty
A forecast for probably “extreme” Northern Lights in a single day on Monday, Sept. 1 and Tuesday, Sept. 2, 2025, has put the spectacular gentle present again within the information.
Whereas the record-breaking shows of Might and October in 2024 are unlikely to be repeated for stargazers this week, it might be an amazing present, and a taster for the 2025-26 Northern Lights viewing season.
That season begins, sarcastically, with September’s longer nights and equinox, and it might be among the best till the mid-2030s, in keeping with specialists.

Northern Lights: ‘Photo voltaic Most’ Interval Continues
The Northern Lights — additionally known as the aurora borealis — happen when charged particles from the solar speed up down Earth’s magnetic area traces and collide with molecules excessive in Earth’s ambiance. That interplay produces the inexperienced and crimson lights. Nonetheless, it’s when there are extra charged particles that the aurora outcomes. That occurs when the solar is at its most lively.
“We’re presently in photo voltaic most, when the solar is most lively, resulting in greater probabilities of photo voltaic storms,” mentioned aurora hunter Wil Cheung, who’s internet hosting an aurora cruise to Norway in October, in an interview. “This era ought to proceed for just a few extra years, however from 2027 onwards we’d count on a gradual wane in exercise.”
Photo voltaic most is the height of our star’s cycle. “The eleven-year photo voltaic cycle is now at what we name the photo voltaic most,” mentioned Chad Blakely, founding father of Lights Over Lapland, in an e-mail. “This implies the frequency and depth of the photo voltaic storms that work together with our ambiance, inflicting the aurora, are at their most intense.”

Northern Lights: A ‘Double Peak?’
NASA and NOAA scientists suppose the height of the present photo voltaic cycle was in Oct. 2024, although isolating a particular date is just not simple. “Nobody will really know till lengthy after the utmost has occurred, however there have additionally been situations of double peaks up to now,” he mentioned. These double peaks happen when photo voltaic exercise spikes, subsides, after which returns just a few years later. That might be precisely what’s occurring now — or about to occur within the coming months.
“2025 could be the final actually spectacular yr of this cycle.” says Silvena Nonev, a journey skilled at Scandinavia Non-public Excursions. “As soon as the photo voltaic most passes, shows will step by step weaken till the mid-2030s. That makes this yr a uncommon alternative for vacationers who need to see the Northern Lights at their absolute peak.”ForbesThe Night time Sky In September 2025: Two Eclipses, Labor Day Aurora And SaturnBy Jamie Carter
Northern Lights: Sunspot Bands Are Driving Aurora
Shows of the Northern Lights could be traced again to sunspots. Counted daily since 1611, these black zones on the solar’s floor are cooler areas of advanced magnetic exercise. They typically produce photo voltaic flares, which commonly result in enormous clouds of supercharged particles being flung into the photo voltaic system. These are known as coronal mass ejections, and once they head within the path of Earth, they’ll set off geomagnetic storms and shows of aurora. “How we decide the height of photo voltaic cycles is predicated on the position of photo voltaic sunspots,” mentioned Cheung. “It’s clear that there are two distinct areas the place these photo voltaic solar spots happen — the Southern Hemisphere and the Northern Hemisphere.”
Final yr’s most dramatic storms have been linked to bands of sunspots from the solar’s southern hemisphere. Now, the northern band is closing in towards the photo voltaic equator, elevating the prospect of much more storms. This sample suggests the present photo voltaic most might be extended.
“We might be trying on the most intense photo voltaic most on file, with some forecasters predicting this winter to be among the best ever instances to expertise the Northern Lights,” mentioned Blakely.World map of depth and visibility of Northern Lights.

Northern Lights: Why Aurora Chasers Head To The Far North
Greatest for whom? On Might 10, 2024, an excessive geomagnetic storm triggered aurora shows worldwide and was rated as G5 — essentially the most intense type. That had not been seen since Oct. 31, 2000. One thing related was repeated on Oct. 10, 2024, and once more on Dec. 31, 2024. On a few of these events, aurora have been seen as far south as Florida because the auroral oval — which generally sits at about 65 levels north latitude — stretched far to the south. However worldwide auroras should not the norm, even throughout photo voltaic most.
The very best locations to see the Northern Lights will all the time be underneath that auroral oval. “You will need to observe that whereas shows at decrease latitudes like northern U.S. and mid-locations in Europe will drop, areas at greater latitudes — in Canada, Norway, Iceland, Sweden and Finland — will proceed to have aurora shows all through the whole photo voltaic cycle,” mentioned Cheung.
It’s from these areas that you just’ll get extra frequent alternatives to see the Northern Lights, however you’ll even have an opportunity of getting the most effective views of them overhead as a substitute of within the distance. It’s right here the place you’ll have the most effective probability of seeing the auroral corona above your head.ForbesA ‘Blood Moon’ Eclipse And A ‘Planet Parade’: The Night time Sky This WeekBy Jamie Carter
Northern Lights: An ‘Equinox Alert’ Coming Quickly?
It’s doable that we’re on the cusp of the final probability of sturdy aurora within the U.S. and Europe till the mid-2030s. On Sept. 22, 2025, it’s the southward equinox, and it’s when auroras are inclined to peak. Based on the Russell-McPherron impact, an idea launched by scientists at UCLA in 1972, Earth’s axis aligns perpendicularly to the sun-Earth line throughout an equinox. That creates superb circumstances for a reconnection between the photo voltaic wind and Earth’s magnetic area.
It may well open “cracks” in Earth’s magnetosphere, permitting the charged particles from the solar that make up the photo voltaic wind to penetrate extra successfully. These particles funnel alongside Earth’s magnetic area traces in direction of the poles, intensifying auroral shows. There could be a lag, making early October a chief window for aurora viewing not simply within the far north, however at mid-northern latitudes.
It’s an expertise that won’t come once more for a decade or extra.
Wishing you clear skies and extensive eyes.
