US EditionStrong Aurora Alert Issued For 21 U.S. States Sunday — What To Know
- A strong G3-class geomagnetic storm is expected on March 23, allowing the Northern Lights to be visible from 21 U.S. States, including as far south as Nebraska and Indiana.
- NOAA reported a coronal mass ejection from March 21 that is set to interact with Earth's magnetic field on March 23.
- NOAA notes that G3 storms can be seen as far south as Illinois and Oregon, making northern skies particularly promising for observing the Northern Lights.
- The Russell-McPherron effect increases the likelihood of auroras during equinoxes, with displays potentially visible at latitudes up to 40 degrees north due to the peak solar cycle activity.

Northern lights could be spotted in the night sky early this week. Can Mass. see the aurora?
Earth could see a geomagnetic storm strike the atmosphere, producing the vibrant northern lights, or aurora, over parts of the United States, including Massachusetts. For Tuesday, space weather forecasts from the National Oceanic and Atmospheric Administration anticipate a coronal hole on the sun’s surface could produce high-speed streams that should impact Earth’s atmosphere.
Map: Chance for some to see northern lights sparked by ‘fast’ coronal mass ejection
(NEXSTAR) — Some may have the chance to see the northern lights on Sunday thanks to an eruption of solar material colliding with Earth's atmosphere. A coronal hole high speed stream, or CH HSS, was spotted on the sun on Friday, NOAA's Space Weather Prediction Center reported. A CH HSS can cause geomagnetic storms on Earth to reach G1 or G2 levels — which could, in turn, spark more northern lights. While the SWPC warned that lower-level geomagnet…
