Northern Lights Tonight: Top 5 things you need to know about this rare solar storm
The sun is unleashing a massive solar storm, pushing the aurora borealis far south of its usual polar haunts tonight. Here’s your essential guide to catching the display.
- Check your local KP index: The key to seeing the northern lights tonight is a high planetary K-index, which measures geomagnetic activity. A KP of 5 or higher means a visible show for northern US states, while a KP of 7 could bring colors to the Midwest and even parts of the central plains. Apps like “My Aurora Forecast” give real-time updates.
- Find a dark, unobstructed view with no light pollution: You need to get away from city lights. Head to a rural area, a state park, or a dark-sky preserve. Look north between 10 PM and 2 AM local time, and let your eyes adjust for at least 15 minutes in the dark. Smartphone cameras with night mode often capture the aurora better than the naked eye.
- Expect dynamic and fast-moving colors: Unlike a static glow, tonight’s storm is predicted to be highly active. You might see shifting curtains of green, pink, and even red if the storm is strong. The best moments happen in sudden bursts, so stay patient and keep scanning the northern horizon.
- Know your region’s visibility window: For tonight, the best odds are in Canada, Alaska, and the northern tier of the US from Washington to Maine. However, a severe G4-level storm could push the aurora as far south as Oregon, Iowa, and Pennsylvania. Check NOAA’s Space Weather Prediction Center for your specific latitude.
- Prepare for photo success without fancy gear: You don’t need a professional camera. Use a smartphone with manual settings or a “Pro” mode. Set ISO to 800-3200, shutter speed to 5-15 seconds, and use a trip
