Web2 days ago · The development was reported by SpaceWeather.com which noted on its website, “NOAA forecasters say that a CME might deliver a glancing blow to Earth's magnetic field today. It left the sun on April 7th, propelled an erupting filament of magnetism. Minor geomagnetic storms are possible if/when the CME arrives”. WebSpace weather refers to variations in the space environment between the Sun and Earth (and throughout the solar system). Some space weather events, called coronal mass ejections”, start as eruptions from the sun’s surface. These events are common, occurring on average two times a day during the most active period of the 11-year solar cycle.
