Many skywatchers dream of seeing the northern lights, or aurora borealis. Although places like Alaska, Iceland, and Norway are well-known for their spectacular shows, more and more people are wondering, “Can you see the northern lights in Illinois?” Surprisingly, the answer is yes—though sightings are uncommon and need perfect circumstances.
This guide will cover the northern lights in Illinois, its science, the finest viewing locations, professional advice to improve your prospects of seeing this awe-inspiring event, and how and when to see them.
A Quick Introduction to the Northern Lights
Colorful light displays that sweep across the sky are produced by charged solar particles colliding with gasses in Earth’s atmosphere. Most often, these lights are seen close to the magnetic poles in the far north or south.
Located far farther south from the auroral oval, Illinois only sees the aurora under certain circumstances—usually during severe geomagnetic storms pushing the aurora visibility line farther south.

Is it possible to view the Northern Lights in Illinois?
Yes, although uncommon. Usually, the northern lights in Illinois are seen only during times of significant solar activity, called geomagnetic storms. NASA and NOAA’s Space Weather Prediction Center said the aurora has to be at least Kp index 7 to be seen as far south as Illinois.
Throughout northern Illinois in 2023, several aurora sightings were recorded, including in Rockford, DeKalb, and the Chicago outskirts. Compared to the bright curtains seen in higher latitudes, these shows usually be pale and near the horizon.

Top Illinois Locations to View the Northern Lights
Although any dark area improves viewing, here are the best places in Illinois suggested by skywatchers:
- Minimal light pollution and broad open skies in Apple River Canyon State Park (Jo Daviess County).
- 🌌 Middle Fork River Forest Preserve (Vermilion County) – The only International Dark Sky Park in Illinois.
- Popular among local photographers for night sky images, Shabbona Lake State Park (DeKalb County).
- 🌌 Rural locations north of Rockford and Galena—Closer to the Wisconsin border, which raises visibility chances.
- Chicago residents should drive at least 50 miles away from the city lights for a fair possibility of seeing the aurora.
Advice on Taking Pictures of Illinois Northern Lights
Photographing the rare aurora in Illinois calls for planning. Here are a few professional tips:
- Photo Keep your camera steady during lengthy exposures by using a tripod.
- 📷 Manual controls:
- Shutter: 10–20 sec
- ISO: 1600–3200
- Aperture: f/2.8 or widest accessible
- Shutter: 10–20 sec
- Camera Shoot north; the aurora will typically be seen low on the northern horizon.
- Photo Pre-peak test shots: While anticipating more activity, verify focus and exposure.
A camera’s sensor can sometimes catch hues undetectable to the naked eye even under weak aurora.
What Makes Aurora Visible in Illinois?
A severe geomagnetic storm is the main driver of aurora visibility this far south. These storms occur when a coronal mass ejection (CME) from the sun strikes Earth’s magnetic field.
The auroral oval grows during such storms, so visible over northern U.S. states including Illinois. During significant solar occurrences in 1958, 1989, 2003, and 2023, notable auroras were historically seen as far south as Illinois.
NASA claims the sun is nearing the solar maximum of its 11-year cycle in 2025, therefore aurora sightings might start to happen more often during the next several years.
