Don’t Miss These Must-See Sky Events in September 2025

The start of the month of September is a good time to check out what is happening in the coming weeks in the night sky. Highlights of the month include a total lunar eclipse and Saturn at opposition. The celestial events calendar could kick off with a bang with a potential Aurora Borealis show. Here is a look at the September astronomical calendar.

Northern Lights Could Shine

More than a dozen states could be in for a real treat on Monday and Tuesday night. Experts are predicting that the northern lights could make an appearance over the skies of Canada and the northern U.S. This could end up being one of the best opportunities to see the Aurora Borealis all year.

The lights are in the cards after an eruption on the sun this weekend sent a mass of particles into space and headed to Earth. The arrival of the charged particles in the atmosphere will trigger the colorful lights.

The Space Weather Prediction Center, out of the National Oceanic and Atmospheric Administration (NOAA), issued a geomagnetic storm watch on September 1 and 2. The agency said that conditions are expected to reach a level 3 out of 5.

The lights are predicted to dance around the skies after the sun goes down as far south as Pennsylvania, Nebraska, Indiana, and Oregon. You may be able to capture the red and green glow from the lights in areas farther south when using a long-exposure camera.

While the upcoming Aurora Borealis show is not predicted to reach the level of visibilty provided in 2024, it will still be one of the best chances to see this display since the spring.

The northern lights can be elusive during the summer months thanks to the shorter nights. The fading daylight heading into September will provide a better chance to catch this dazzling display from Mother Nature.

You will increase your chances of seeing the beauty if you head out to a dark area that offers a clear view of the northern horizon. Be sure to give your eyes time to adjust to the darkness before trying to spot the light.
