Oct. 28, 2023 (Bing) -- Scientists are monitoring two coronal mass ejections (CMEs) that erupted from the sun on Oct. 26 and 27.
CMEs are large clouds of plasma and magnetic fields that are hurled into space by the sun. They can travel at speeds of millions of miles per hour and reach Earth in a few days.
According to the Space Weather Prediction Center (SWPC), one of the CMEs arrived at Earth on Oct. 29th and caused a minor G1 geomagnetic storm. This means that the Earth's magnetic field was disturbed by the solar wind and some weak auroras were visible at high latitudes.
The SWPC also issued a geomagnetic storm watch for Oct. 30th, when another CME is expected to hit Earth's magnetosphere. This could cause more intense auroras and possibly some minor impacts on power systems and radio communications.
