A powerful solar storm hit Earth on Thursday, according to the US National Oceanic and Atmospheric Administration (NOAA). Agencies are concerned that the storm could hamper efforts to deal with Helene and Milton. According to NOAA's Space Weather Prediction Center (SWPC), a coronal mass ejection (CME) erupted from the Sun on Tuesday evening and at 11:15 a.m. (EST) on Thursday at a speed of about 1.5 million mph (2.4 million km/h). Reached Earth from.
Xinhua news agency quoted SWPC as saying that the storm has reached G4 (severe) level. It is classified as a G4 Geomagnetic Storm Watch. A G4 or greater geomagnetic storm watch remained in effect Thursday and Friday. The SWPC issues warnings and alerts regarding geomagnetic storm conditions. According to NOAA, the storm could have negative impacts on ongoing recovery efforts for Hurricanes Helene and Milton, including radio blackouts, strain on the power grid, and reduced GPS services.
A CME is a massive ejection of magnetic fields and plasma matter from the Sun's corona. When it comes towards the Earth it causes major disturbances in the Earth's magnetic field. It is called geomagnetic storm. This increases the risk of radio blackouts and power cuts.
