A “strong to severe” geomagnetic storm hit Earth yesterday, NASA says, after the sun unleashed a burst of plasma from a turbulent region two days prior.
The region, known as sunspot 1302, has sent forth a few blasts of energy called solar flares, including a flare and an accompanying belch of plasma called a coronal mass ejection (CME) on September 24. The CME reached Earth two days later and impacted the planet’s magnetic shielding, exposing high-altitude satellites to charged particles and magnetic fields, according to NASA. The CME’s arrival also produced low-latitude auroras—spaceweather.com reports that sightings of the not-so-northern lights were reported in Michigan, New York, South Dakota, Maine and Minnesota.

According to the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center, high-accuracy GPS services were affected by the storm. [ http://www.swpc.noaa.gov/ ]
An earlier flare from sunspot 1302 was more powerful but did not aim a blow at Earth—the X1.9-category flare captured on the video below by NASA’s Solar Dynamics Observatory erupted about three hours before the M-class, or medium-size, flare accompanying the CME. X is the most powerful class of flare, and the numerical suffix indicates the relative brightness of the flare within that class. (An X9 is the brightest classification on the scale.)
