The National Oceanic and Atmospheric Administration (NOAA) is predicting a higher chance of northern lights sightings across more states in the northern US this week. A geomagnetic storm on Tuesday pulled the phenomenon farther south, making it visible in parts of Wyoming, Iowa, New York, Vermont, and New Hampshire. The forecast indicates that auroral displays will be “quite pleasing to look at” for those in the right areas.
Wednesday’s forecast shows a Kp index of four, suggesting brighter and more active light displays. Similar displays are expected through Friday, with a maximum Kp index above or near three projected for Thursday and Friday. Minor to moderate radio blackouts are also possible, primarily affecting high-frequency radio communications.
Alaska and northern Canada will have the best chance of seeing the northern lights, while parts of South Dakota, Wisconsin, and Maine are less likely to be affected. To view the northern lights, a north-facing location with minimal light pollution is recommended, preferably between 10 pm and 2 am local time.
For capturing the northern lights on camera, experts suggest using a tripod, wide-angle lens, aperture of four or less, and focusing on the furthest possible setting. A regular phone can be used, but turning on night mode and disabling flash is recommended. The northern lights are caused by electrons colliding with oxygen and nitrogen in the Earth’s atmosphere, resulting in colorful displays.
This increased solar activity comes after a “solar maximum” achieved in October, which coincides with a “solar minimum.” These events lead to solar flares and coronal mass ejections, responsible for the aurora borealis displays.
