You can’t just guess the aurora’s location—it’s not a weather app for your mood. Use NOAA’s Aurora Forecast or the “My Aurora Forecast” app. They tell you the Kp-index, which is a fancy number for how strong the show will be.
A Kp of 5 or higher? That’s the golden ticket. A Kp of 2? You’ll be staring at a gray sky like a sad penguin. Check the cloud cover too—the aurora is a diva that hates clouds.

Also, look at the solar wind speed. If it’s fast and steady, you’re in for a treat. If it’s sleepy, grab a blanket and watch Netflix instead.
