IKI RAS: Solar Plasma Ejection to Reach Earth on the Night of September 2nd

Scientists from the Laboratory of Solar Astronomy at the Space Research Institute (IKI) of the Russian Academy of Sciences have issued a warning regarding an impending solar plasma ejection. This celestial event is anticipated to impact Earth on the night of September 2nd, potentially triggering powerful geomagnetic storms. Initial predictions suggest these storms could reach a G3 level, with a slight chance of intensifying further to G4, while the probability of an extreme G5 storm remains below 1%.

The announcement follows observations of two significant coronal mass ejections (CMEs) from the Sun. One of these plasma clouds, of moderate size, was directed towards Mercury and Venus, but the other was unequivocally aimed directly at our planet. Through sophisticated modeling, the trajectory of yesterday`s plasma ejection along the Sun-Earth line has been analyzed. According to these calculations, the solar material is expected to arrive at Earth during the late hours of September 1st, specifically between 11 PM and midnight Moscow time.

The plasma is traveling at a remarkable speed, estimated to be around 900 kilometers per second. Consequently, upon its collision with Earth`s magnetosphere, intense auroras are predicted to occur, potentially visible at latitudes as low as 55 degrees for several hours post-impact.

Scientists continue to monitor solar activity closely, noting a sustained high probability of further powerful solar flares and subsequent plasma ejections directed towards Earth. A more precise geomagnetic forecast, detailing the exact timing and intensity of the anticipated storms, is expected to be released later on Sunday.
