Dancing Lights Tonight: Aurora Borealis Forecast for North America”
The mesmerizing Aurora Borealis, or Northern Lights, is set to dazzle skies across North America tonight and tomorrow night, offering a potential treat for stargazers.
This forecast, powered by the OVATION model, predicts the intensity and location of the aurora using geomagnetic activity (Kp index) data for the hours between 6 PM and 6 AM Central Time. Here’s what to expect and where to look.
What the Aurora Forecast Shows
The forecast features two maps—one for tonight and another for tomorrow night—highlighting the potential aurora and its “viewline.
” This viewline indicates the southernmost points where the aurora might be visible low on the northern horizon.
The green ovals on the maps mark the expected location of the aurora, centered around Earth’s magnetic pole. When conditions intensify, these ovals turn red, signaling brighter and more active displays.
Key Viewing Tips
Timing: The aurora is most visible during the hours just after sunset and before sunrise.
It cannot be seen during daylight.
Location: You don’t need to be directly under the aurora to witness its beauty.
Bright auroras can be observed from up to 1,000 km away, provided skies are clear and light pollution is minimal.
Weather Conditions: Clear, dark skies away from city lights offer the best chance to catch the display.
Short-Term Updates and Real-Time Tracking
For those seeking up-to-the-minute information, the Aurora – 30 Minute Forecast page provides short-term forecasts and data from the past 24 hours.
Additionally, the SWPC’s new experimental Aurora Dashboard offers a consolidated view of resources to keep aurora enthusiasts informed.
The Science Behind the Lights
Auroras occur when charged particles from the sun collide with Earth’s atmosphere, creating shimmering curtains of green, red, and sometimes even purple.
Their intensity depends on solar activity, geomagnetic storms, and the alignment of Earth’s magnetic field.
Prepare for the Show
If you’re located near or north of the forecasted viewline, grab your binoculars, bundle up, and head outdoors tonight or tomorrow night.
Keep your eyes on the northern horizon for a chance to witness this spectacular natural phenomenon.
Don’t forget to check updates on the SWPC website to stay informed about changing conditions. Happy aurora hunting!
