Earth is set to experience significant geomagnetic storms, potentially reaching the second-highest intensity level, on September 2nd. This forecast comes from the Laboratory of Solar Astronomy at the Space Research Institute (IKI) of the Russian Academy of Sciences, attributing the phenomenon to a recent emission of a plasma cloud from the Sun.
This event follows earlier reports from scientists about a powerful solar flare accompanied by a plasma ejection, marking the second such occurrence within a single day. Prior to this, a moderately sized plasma cloud was directed towards Mercury and Venus, which are currently positioned in the same angular sector to the Sun`s right.
Data from space coronagraphs LASCO and CCOR-1 have confirmed a solar plasma ejection heading towards Earth, originating from an M2.76 flare detected two and a half hours ago. It is anticipated that this solar material will reach Earth`s orbit by Tuesday, September 2nd, triggering geomagnetic storms categorized as G2-G4. These levels represent a significant disturbance, just below the maximum G5 intensity.
Researchers stress that the primary danger currently lies in the possibility of repeat ejections. Such subsequent events are considered highly probable given the substantial reserves of flare energy still present within the Sun.
This scenario is reminiscent of the situation in May 2024, when the most intense geomagnetic storms recorded in two decades were not caused by a single colossal explosion, but rather by a sequence of successive, medium-sized mass ejections. Scientists continue to monitor solar activity closely for further developments.
