Top 5 Things You Need to Know About This Stunning Northern Lights Display Over the U.S.
- The 2024 "solar maximum" is producing the most intense northern lights show in over two decades. Experts say the sun's heightened magnetic activity is driving this surge, meaning frequent, vivid aurora events are likely to continue through next year.
- This week's display was triggered by a powerful "cannibal CME" – a fast-moving solar storm that overtook a slower one, supercharging the geomagnetic activity. This phenomenon caused the northern lights to be visible as far south as Texas and Florida for the first time in years.
- The best way to see them now is to use a long-exposure camera mode on your smartphone. Even if the colors are faint to the naked eye, a 3-10 second camera exposure can reveal brilliant greens, pinks, and purples that are otherwise invisible in light-polluted city skies.
- To maximize your viewing chances, look towards the northern horizon between 10 PM and 2 AM local time on clear nights. Sites like the NOAA Space Weather Prediction Center offer real-time aurora forecasts and "Kp-index" alerts that predict visibility in your specific zip code.
- A little-known safety tip: avoid light pollution from your phone screen. It takes at least 20 minutes for your eyes to fully adjust to the dark, so minimize screen time and use a red-light app to preserve your natural night vision for spotting the faintest auroral arcs.
