LOOK UP TONIGHT! The aurora borealis—typically only visible in high north latitudes—was visible last night as far south as Louisiana—and is predicted to show off its colors again tonight! Even rarer—we’re seeing reddish-pink instead of the usual greens. Why? Bob Berman explains.

Rare, Red Auroras Visible!

On the evening of Friday, May 10, extensively visible Northern Lights (aurora borealis) appeared across the United States. And we expect more sightings tonight, Saturday, May 11! 

The current powerful solar storms created naked-eye aurorae seen far, far south of the normal places. Thanks to the supercharge of some intense sun eruptions, we had friends in Louisiana and Florida report rare sightings.

  • Last night’s display, from all locations, didn’t show only the usual large blotches but also pale vertical streaks, even directly overhead.
  • In addition, extensive faint red blotches covered large parts of the sky. The red was very, very unusual since green is the normal, commonly visible auroral color. Cameras showed other colors, too, and much more vividly than were actually seen directly by anyone. 

The naked-eye red was seen from many locations, which is extremely unusual and indicates very high altitude auroras mostly caused by sparse glowing oxygen.

We didn’t get detailed patterns such as rustling curtains, as seen in our annual Northern Light expeditions to places near the Arctic Circle. (Join me there next March by checking out SpecialInterestTours.com )

To give a sense of the rarity of the current auroral activity, widespread multi-hour displays in the overhead sky, in the contiguous U.S., were seen in clear skies without obscuring bright moonlight by the unaided eye on March 13, 1989, then in October 2020, then October 2021 and not since then. These dates omitted briefer displays, and a few were seen in localized clear skies when most regions were extensively cloudy.

What are the Northern Lights?

The aurora borealis are colorful, shimmering curtains of light that appear in Earth’s sky, often looking like dancing ribbons of green and purple. They originate from the Sun itself! 

The stormy, active Sun constantly throws off energized particles from its upper atmosphere. When these particles travel at high speeds toward Earth, our planet’s upper atmosphere protects us. The particles collide with gases in Earth’s atmosphere, creating colorful lights in the sky.

  • In the Northern Hemisphere, the event is called the aurora borealis, which means “dawn of the North,” or the northern lights.
  • In the Southern Hemisphere, it is called the aurora australis, which means “dawn of the South,” or the southern lights.


2024 Brings the Best Northern Lights in 20 Years

The Sun has weather just like Earth! At times, the Sun is very stormy and ejects more charged particles and solar flares, which are large eruptions of electromagnetic radiation. This creates the northern and southern lights, or auroras.

This storminess is especially severe when the Sun is nearing the peak of its 11-year solar cycle and its “solar maximum.” Current Solar Cycle 25 began in December 2019. Initially, it was predicted to end around 2030, and scientists forecasted that it would peak, or reach the solar maximum, around July 2025  (+/ 8 months). 

However, as of June 2023, experts came to believe that the Sun may peak earlier than expected—possibly in mid- to late 2024. Read more about Solar Cycle 25.

What Causes the Northern Lights?

The streams of charged particles that erupt from the Sun’s surface can travel at speeds of up to a million miles per hour. As strong solar activity enters the Earth’s magnetic field, the particles (electrons and protons) collide with gases in the upper atmosphere, which causes the gases to glow. As billions of collisions occur in sequence, auroras appear to move or “dance” in the sky.

Because of the shape of Earth’s magnetic field, the charged particles stream towards the poles. This is why auroras are most often seen in the high latitudes near the North and South Poles. They can appear as curtains of light moving across the entire sky and sometimes appear as huge arcs and pillars of color that dance and float through the dark.

Auroras often start with a green glow. You could see shades of green, red, yellow, purple, and blue. The colors depend on the energy level of each gas particle and which gas particles are present. The movement is also beautiful. When the solar winds ripple through the magnetic field, the curtains of light appear to dance, brighten, or fade.

One of the most colorful auroras occurred in March 1989. It was visible in Canada and the United States and as far south as Mexico. The electrical surge that accompanied it was so strong that parts of Canada were blacked out all night!

When Can You See Auroras? When Are the Northern Lights?

While auroras are triggered at any time by strong solar activity, the traditional aurora-watching season is during the weeks before and after the vernal equinox and autumnal equinoxes, when we transition between seasons.

Why? According to NOAA, the times around the equinoxes are when the Earth is affected more directly by the Sun’s geomagnetic storms, which cause disturbances in Earth’s magnetic field. This seems to be related to the Earth’s orbit around the Sun and the position of our planet’s magnetic poles at any given time of year.

The best time of the day to spot auroras is late at night and in the early morning (from 10:00 P.M. to about 3:00 A.M.). Look north on a clear, moonless night from a dark place away from city lights.


Where Can You See the Northern Lights?

Traditionally, the northern lights are most commonly seen at high latitudes. Aurora fans will often travel to Alaska on a tour to see the sights. 

However, if you live in Canada or the northern-tier states (Maine, Michigan, etc.), you are likely to see the northern lights from right where you are if you make an effort. 

However, in 2023 and 2024, what’s exciting is that people are reporting viewings not only in the usual places, such as the northern-tier states and Canada, but also in the Midwest and even lower Midwest. There have even been sightings in southern states down to North Carolina, central California, and even Arizona!

Why is this happening? Again, it’s all related to the Sun and the solar cycle. The current Solar Cycle 25 is “heating up,” which means that the Sun is especially active; this increased activity in the Sun’s magnetic field will also expand the visibility of the northern lights. When there are massive solar storms (as is more likely near the solar maximum), the lights will appear farther south. Learn more about Solar Cycle 25.

Just get out away from city lights and look up toward the north.

Fun Facts About the Northern Lights

  • No two light shows are ever the same.
  • The most common colors are green and pink, but the aurora may also appear to be purple, red, blue, or yellow.
  • It’s oxygen in the atmosphere that creates the green light, while nitrogen causes the blue light.
  • A single active display can produce one trillion watts of electricity.
  • Some people claim that they have heard the northern lights hiss and crackle.

Web sites such as Spaceweather.com will report on solar explosions and forecast upcoming auroras. NOAA Space Weather Prediction Center also reports solar flare activity.  If you have a shortwave or CB radio, hearing disturbances or skips can also a be a telltale sign.
