Aurora Alert: Northern Lights Visible Far South

Northern lights may be visible across several U.S. states between Sunday, March 29, and Monday, March 30. This possibility arises from a geomagnetic storm watch issued by NOAA, anticipating a G1 or G2-class storm. The event is linked to a coronal mass ejection (CME), a cloud of charged particles from the sun, expected to brush against Earth's magnetic field.

The CME originated from an M3.9-class solar flare on March 29, stemming from sunspot AR4403. This solar activity, coupled with an expected high-speed stream of solar wind, could enhance auroral visibility. NOAA predicts unsettled to active conditions persisting through March 31.

Residents in northern U.S. states, including Alaska, Washington, Idaho, Montana, North Dakota, South Dakota, Minnesota, Wisconsin, Michigan, and Maine, may observe the aurora on the northern horizon. Optimal viewing requires dark conditions, away from light pollution, and a clear view of the northern sky. A bright waxing gibbous moon may impact visibility of fainter displays.

Recent increases in sunspot activity suggest a higher likelihood of solar eruptions and subsequent northern lights in the coming week. Scientists are closely monitoring for additional flares and potential Earth-directed eruptions. Space weather forecasts indicate that geomagnetic effects could allow auroras to be seen farther south than usual.
