A powerful solar outburst is predicted to graze Earth this weekend, potentially triggering power grid disruptions and making colorful auroras visible from much of the northern U.S.
The outburst, known as a coronal mass ejection (CME), erupted from the sun on Jan. 21 and is forecast to strike Earth's magnetic field late Friday night (Jan. 24) or early Saturday morning (Jan. 25), according to the National Oceanic and Atmospheric Administration's (NOAA) Space Weather Prediction Center.
