Forecasters at the Space Weather Prediction Center (SWPC) warn a solar flare will hit Earth Today, potentially affecting power grids and could bring dazzling Northern Lights to northern latitudes.

SWPC issued a "G2 (Moderate) geomagnetic storm watch" for Monday and Tuesday. The geomagnetic storm could affect power grids primarily poleward of 55 degrees Geomagnetic Latitude. Satellite "orientation irregularities" may occur; increased drag on low Earth-orbit satellites is possible, it said, adding, "high-frequency radio propagation can fade at higher latitudes."
