- During the May 2024 geomagnetic storm, auroras were visible as far south as 26°N latitude, reaching parts of Florida, Texas, and even northern India.
- The storm that triggered this event was rated G5 — the most powerful geomagnetic storm classification, the first seen since 2003.
- Solar Cycle 25 is now at its peak, producing sunspot counts 30% higher than scientists originally predicted for this cycle.
- Aurora displays at low latitudes occur when Earth's magnetosphere is compressed so severely that the auroral oval expands by up to 20 degrees southward.
What if the sky above Mumbai started glowing green and crimson? In May 2024, the northern lights — that ethereal Arctic spectacle — shattered every expectation and blazed across skies at record low latitudes, stunning millions of people who had never imagined witnessing an aurora from their backyards. The science behind this jaw-dropping event reveals just how violently alive our Sun truly is, and why the northern lights low latitudes phenomenon may become far more common in the years ahead.
What Are the Northern Lights and Why Do They Glow?
The northern lights, scientifically known as aurora borealis, are one of Earth's most breathtaking natural light shows — a shimmering curtain of green, red, purple, and blue that drapes across polar skies. They are born from a cosmic collision: charged particles streaming from the Sun at up to 800 kilometres per second slam into Earth's magnetic field and get funnelled toward the poles. When these energetic electrons and protons collide with oxygen and nitrogen atoms in the upper atmosphere at altitudes of 100 to 300 kilometres, they excite those atoms, causing them to release energy as visible light. Green is the most common colour, produced by oxygen at around 100 km altitude, while red auroras — seen dramatically during the 2024 event — come from oxygen at higher altitudes above 200 km. The colours you see depend entirely on which gas is being excited and at what altitude the collision occurs. Normally, this celestial firework is confined to a ring around the Arctic and Antarctic poles known as the auroral oval, sitting between 65° and 72° latitude — far from most of humanity.
What Causes Auroras to Appear at Low Latitudes?
For auroras to blaze at record low latitudes, something extraordinary must push the auroral oval dramatically southward — and that something is a powerful geomagnetic storm. When the Sun ejects a massive cloud of magnetised plasma called a Coronal Mass Ejection, or CME, it can travel 150 million kilometres to strike Earth's magnetosphere in just 17 to 72 hours. If the CME carries a southward-oriented magnetic field — called a negative Bz orientation — it tears open Earth's protective magnetosphere like a zipper, allowing solar particles to penetrate far deeper than usual. During intense storms, the auroral oval can expand from its normal position near 65°N all the way down to 40°N, 30°N, or even lower in the most extreme cases. Think of Earth's magnetosphere as a giant invisible shield — a G5 geomagnetic storm essentially punches a hole in that shield, letting the aurora flood southward. The Dst index, which measures how severely Earth's magnetic field is disturbed, plummeted to approximately -412 nanoteslas during the May 2024 storm — among the most extreme readings ever recorded in the modern era. This magnetic violence is what gifted skywatchers in subtropical regions with an aurora display that many will never forget.
🤔 Did You Know?
During the record May 2024 aurora event, people in Ladakh, India — over 5,000 km south of the Arctic Circle — photographed vivid red and purple lights dancing across the Himalayan sky for the first time in living memory.
The May 2024 Record-Breaking Geomagnetic Storm
On May 10–11, 2024, Earth was struck by a barrage of at least seven CMEs that had erupted from a single active sunspot region catalogued as AR3664 — a sunspot cluster so large it was visible to the naked eye through solar filters, spanning an area 17 times wider than Earth itself. NOAA's Space Weather Prediction Center elevated the geomagnetic storm to G5 — the highest possible rating on the five-point scale — for the first time in 21 years since the legendary Halloween Storms of 2003. The storm produced auroras visible across an astonishingly wide swathe of the planet, and social media exploded with thousands of photographs from places where aurora had never been photographed before. Aurora alerts were issued across Europe, North America, Asia, and even parts of the Middle East and North Africa. Scientists monitoring the event described it as a once-in-two-decade occurrence at minimum, while some compared its intensity to the 1989 Quebec Blackout storm that knocked out power for six million Canadians in just 90 seconds. Crucially, the May 2024 storm arrived during daytime for much of Asia, yet the nighttime windows in India, Pakistan, and China were still enough to produce striking photographic evidence of the aurora at historically low latitudes. This storm will be studied by space weather scientists for decades to come.
Where in the World Were Auroras Spotted?
The geographic reach of the May 2024 northern lights was simply staggering, rewriting the map of where auroras can realistically be seen. In North America, credible aurora sightings and photographs poured in from Florida (approximately 27°N), Puerto Rico (18°N), and New Mexico — locations where the northern lights are virtually unheard of. Across Europe, vivid auroras lit up the skies of Spain, Portugal, southern France, Greece, and even parts of Morocco in North Africa, sitting near 32°N latitude. In Asia, arguably the most astonishing reports came from Ladakh and Himachal Pradesh in India, where amateur astronomers and tourists photographed unmistakable red and magenta aurora pillars rising above the Himalayan peaks. Reports also emerged from parts of China, Taiwan, and the Arabian Peninsula, where observers were stunned to see the sky turn deep crimson after midnight. Australia and New Zealand witnessed the southern counterpart — the aurora australis — appearing as far north as Queensland. Social media platforms like X (formerly Twitter) and Instagram were flooded with over 11 million aurora-related posts within 48 hours, making it one of the most globally documented natural events in history. The event proved, beyond any doubt, that the northern lights low latitudes phenomenon is real, verifiable, and deeply rooted in powerful solar physics.
Solar Cycle 25: Why the Sun Is More Furious Than Ever
To understand why record low latitude auroras are happening now, you need to understand the Sun's 11-year heartbeat — the solar cycle. The Sun alternates between periods of low activity called solar minimum and frenetic periods of maximum activity called solar maximum, during which sunspots, flares, and CMEs multiply dramatically. We are currently deep into Solar Cycle 25, which began in December 2019, and its solar maximum is occurring right now in 2024–2025. Here is the shocking twist: when Solar Cycle 25 began, NOAA and NASA predicted it would be a relatively weak, below-average cycle — yet it has turned out to be one of the strongest in decades, with monthly sunspot counts running up to 30% above the official forecasts. The sunspot number in early 2024 reached values not seen since Solar Cycle 19 in the 1950s, which was one of the most powerful cycles ever recorded. This means Earth is being bombarded with more frequent and more intense CMEs than scientists anticipated, sharply raising the probability of G4 and G5 storm events. Solar maximum is expected to remain active through late 2025, meaning the extraordinary aurora displays at low latitudes seen in May 2024 could repeat — and skywatchers around the world should remain alert and ready.
How to See the Northern Lights at Low Latitudes
If you live between 25°N and 50°N and want to witness the northern lights yourself, preparation and timing are everything — because these rare events can flare up with as little as 24 to 48 hours of warning. Your best tool is NOAA's Space Weather Prediction Center website, which issues geomagnetic storm watches, warnings, and alerts in real time, along with smartphone apps like SpaceWeatherLive, My Aurora Forecast, and Aurorasaurus that send push notifications when a G3 or higher storm is detected. Look for nights when the Kp index — a global measure of geomagnetic activity on a 0 to 9 scale — reaches at least Kp 7 or higher to maximise your chances at low latitudes; during the May 2024 storm, Kp hit a rare maximum of 9. Choose a location with dark skies away from city light pollution, lie flat on your back to take in the full sky, and allow your eyes at least 20 minutes to adapt to darkness. Crucially, even if you cannot see the aurora with your naked eye, modern smartphone cameras with night modes are extraordinarily sensitive to the long-wavelength red auroras that dominate at lower latitudes — so always keep your phone ready. The best viewing window is between 10 PM and 2 AM local time, when the sky is darkest and geomagnetic activity is often strongest. Patience and preparation could reward you with one of the most magnificent sights nature has ever produced.
What Are the Risks of Extreme Geomagnetic Storms?
While the aurora spectacle fills us with wonder, the same geomagnetic storms that produce them carry serious, even civilisation-threatening risks that scientists are urgently working to understand and mitigate. During a G5 storm, the rapidly changing magnetic fields on Earth's surface induce powerful electrical currents in long conductors like power grids, pipelines, and railway lines — a phenomenon called geomagnetically induced currents, or GICs. The most notorious example remains the March 1989 Quebec Blackout, when a G5 storm collapsed the entire Hydro-Québec power grid in 92 seconds, leaving six million people without electricity for up to nine hours in freezing temperatures. A storm on the scale of the 1859 Carrington Event — the largest geomagnetic storm in recorded history, which literally set telegraph machines on fire — would today potentially destroy hundreds of large transformers worldwide that take 12 to 18 months to manufacture and replace, causing economic damage estimated between $1 trillion and $2 trillion. Satellites in low Earth orbit experience increased atmospheric drag during strong storms, threatening GPS accuracy and orbital station-keeping — during the February 2022 storm, SpaceX lost 40 of 49 newly launched Starlink satellites due to increased atmospheric density. High-frequency radio communications used by airlines for polar routes are also severely disrupted, forcing costly flight diversions. The May 2024 storm caused some power grid fluctuations in North America and mild GPS errors, but it was a stark reminder that as our civilisation becomes more technologically dependent, our vulnerability to space weather grows every single year.
Final Thoughts
The northern lights blazing at record low latitudes in 2024 is not merely a beautiful anomaly — it is a neon sign written across the sky in green and crimson, reminding us that we live on a magnetically vulnerable planet orbiting a ferociously active star. With Solar Cycle 25 still surging toward its peak, the next spectacular aurora event at low latitudes could be weeks or months away — so download a space weather app today, find your nearest dark sky, and keep your camera ready. The cosmos is putting on its greatest show, and for the first time in history, almost everyone on Earth has a front-row seat.

Frequently Asked Questions
Can northern lights be seen in India?
Yes — during the extraordinary G5 geomagnetic storm of May 2024, northern lights were photographed in Ladakh, Himachal Pradesh, and other high-altitude regions of northern India. These events are extremely rare and require an exceptionally powerful solar storm with a Kp index of 9 to push the aurora that far south.
What Kp index is needed to see aurora at low latitudes?
To see the northern lights at latitudes below 45°N, you generally need a Kp index of at least 7–8, while latitudes below 30°N require a rare Kp 9 — the maximum possible value. The May 2024 storm hit Kp 9, which is why auroras were visible across subtropical regions worldwide.
How often do G5 geomagnetic storms happen?
G5 geomagnetic storms — the most powerful category — occur only a handful of times per solar cycle, roughly every 11 years. Before May 2024, the last G5 event was in October–November 2003 during the Halloween Storms, making the 2024 event the first G5 in 21 years.
