Space weather Twitter account Space Weather Watch published a map outlining the locations the Northern Lights could be seen from. On Friday night, the storm level is G2, according to NOAA, which poses a moderate storm level. Bill Murtagh, the program coordinator at the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center, told the Washington Post that the G3-level storm “does bring the northern lights down into the United States.” These storms are graded based on strength, and on Thursday night, the storm is rated as a strong G3. This spurs “coronal mass ejections,” which project “plasma and pieces of the Sun's magnetic field into the atmosphere.” Geomagnetic storms, according to NPR, are when a coronal hole - which are the spots that look black on the Sun - elicits high winds. The National Oceanic and Atmospheric Administration Space Weather Prediction Center issued a geomagnetic storm watch from Wednesday through Friday.
