Northern Lights alert tonight: 10 US states could see Aurora Borealis glow as solar wind spikes—don’t miss this rare sky moment, timing details, and key viewing mistakes to avoid during peak late-night window

The night sky may show northern lights activity tonight, and people are being told to look up because space weather conditions are becoming more active, according to NOAA’s Space Weather Prediction Center. A stream of fast solar wind particles from the Sun is moving toward Earth and may interact with Earth’s magnetic field, which can trigger auroras.

What causes northern lights tonight

Northern lights happen when charged particles from the Sun collide with gases like oxygen and nitrogen in Earth’s atmosphere, creating glowing colors in the sky, as explained by NOAA space weather experts. Recent space conditions have been mostly calm, with geomagnetic activity staying below storm levels, as per the report by People.


Scientists now expect a change from calm to “unsettled to active” space weather conditions between April 29 and April 30. This change is mainly caused by a high-speed solar wind stream coming from a coronal hole on the Sun, according to NOAA prediction data. There is a chance of a weak G1 (minor) geomagnetic storm during April 29–30 if solar wind impact becomes stronger, according to NOAA storm scale alerts via People.

Northern lights forecast April 2026

NOAA also states that unsettled space conditions may continue into May 1 as solar wind activity slowly persists. Scientists explain in simple terms that the energy needed for auroras already exists, but it must properly align with Earth’s magnetic field for lights to become visible. The best time to see the northern lights is overnight from April 29 into early April 30, especially during late night and pre-dawn hours, according to NOAA timing guidance.

Best time to see aurora borealis

Auroras are most likely to be strongest when the sky is darkest, usually between midnight and early morning, according to space weather experts. The expected activity level may reach a Kp index of up to 4, which is just below official geomagnetic storm strength, according to NOAA scale readings as noted by People. Even small changes in magnetic field direction, especially a stronger southward shift, can suddenly make the aurora brighter and more visible, according to scientists. If conditions are right, northern lights may be seen across northern parts of the United States and most of Canada, according to NOAA visibility maps.

In the US, the best viewing chances are in these 10 stated Alaska and the northern states like Washington, Idaho, Montana, North Dakota, South Dakota, Minnesota, Wisconsin, Michigan, and Maine, according to NOAA. If solar activity becomes stronger than expected, the aurora could move farther south into states like Oregon, Iowa, Illinois, and New York. To watch the northern lights clearly, people should go to a dark open area away from city lights and face the northern sky for the best view.

Darker surroundings make aurora colors look more bright and clear, so avoiding artificial light is very important, according to space observation guidelines cited by People report. People can track real-time aurora activity using NOAA’s 30-minute forecast updates and space weather apps that show solar wind and magnetic field changes. Even a smartphone can capture the aurora if used in Night Mode or Pro Mode with long exposure settings, as suggested by space photography tips.

FAQs

Q1. When can we see the northern lights tonight?

The northern lights may be visible late night on April 29 to early April 30 if space weather conditions become active.

Q2. Where can northern lights be seen in the US?

They are most likely in northern US states like Alaska, Montana, Minnesota, and Michigan, depending on solar activity
