The northern lights, or aurora borealis, are expected to illuminate several states along the U.S.-Canadian border tonight. This prediction comes from forecasters at the National Oceanic and Atmospheric Administration (NOAA), who anticipate minor geomagnetic storms may enhance visibility.
Aurora Borealis Visibility Tonight
Forecasters project a Kp index of four on a scale of nine. This level indicates that the aurora may appear brighter and more dynamic, allowing for wider visibility beyond typical polar regions.
Effects of Geomagnetic Storms
Minor geomagnetic storms result from high-speed solar winds escaping from coronal holes on the Sun. These storms, categorized as G1 on a scale of one to five, can impact power grids and satellites. Despite their mild classification, they significantly enhance the chances of viewing the northern lights further south in the continental U.S.
Regions for Aurora Viewing
Tonight, the aurora borealis may be visible in:
- Washington
- Idaho
- Montana
- North Dakota
- South Dakota
- Much of Minnesota
- Northern Wisconsin
- Northern Michigan
- Northern Maine
- Much of Alaska
Optimal Viewing Conditions
For the best experience, NOAA advises viewers to head north towards the Earth’s magnetic pole in northern Canada. Finding a location with an unobstructed view of the northern sky, away from city lights, will enhance the viewing experience.
The aurora is usually most vibrant around midnight. Therefore, viewers should plan their outings between 10 p.m. and 2 a.m.
Tips for Photographing the Aurora
To capture the northern lights, photography experts recommend the following:
- Use a camera with a wide-angle lens or a low-light capable lens with an aperture of 4.0 or lower.
- For smartphone users, disable the flash and activate night mode.
- Bring a tripod to ensure stability while shooting.
Tonight presents a great opportunity to witness the breathtaking display of the aurora borealis, marking an exciting event for many across these regions.
