WebMar 14, 2024 · A massive eruption of solar material, known as a coronal mass ejection or CME, was detected escaping from the Sun at 11:36 p.m. EDT on March 12, 2024. The CME erupted from the side of the Sun opposite Earth. While resarchers are still gathering data to determine the source of the eruption, it is currently believed that the CME came from … The solar wind is observed to exist in two fundamental states, termed the slow solar wind and the fast solar wind, though their differences extend well beyond their speeds. In near-Earth space, the slow solar wind is observed to have a velocity of 300–500 km/s, a temperature of ~100 MK and a composition that is a close match to the corona. By contrast, the fast solar wind has a typical velocit…
