A massive coronal mass ejection (CME) is hurtling towards Earth, with NASA and NOAA models predicting a strike on June 1. The CME, triggered by an M8.2-class solar flare, has a velocity of approximately 1,938 kilometers per second – one of the fastest recorded this cycle.
The solar eruption, caused by sunspot 4100, will unleash a severe G4-class geomagnetic storm upon impact. This could lead to dazzling auroras visible across Europe and the US, potentially making it one of the most significant space weather events of Solar Cycle 25.
The CME’s arrival is uncertain due to fluctuating solar wind conditions, but it’s expected to trigger immediate geomagnetic disturbances and disrupt power grids, satellite operations, and GPS systems. Scientists emphasize that this event provides critical data for understanding and preparing for the Sun’s unpredictable behavior.
