Currently, Earth is experiencing a significant planetary-scale geomagnetic storm, almost reaching the highest G5 level. Its intensity has reached G4.7, just one-third of a point below the maximum G5. Such strong disturbances are observed due to the arrival of the first of three plasma clouds, ejected as a result of a series of solar flares. Initial forecasts expected only weak activity of G1–G2 levels, but the actual impact turned out to be dozens of times stronger.
Experts report that the plasma cloud from yesterday’s record-setting X5.16 solar flare, moving at an unusually high velocity, caught up with and compressed earlier ejections, increasing their density and magnetic impact.

The National Oceanic and Atmospheric Administration (NOAA) had to switch from the primary ACE satellite to the backup DSCOVR, which operates intermittently and provides distorted readings. Nonetheless, signal analysis shows a sharp increase in solar wind density and temperature, as well as record-strong magnetic induction at historical highs.
Scientists believe that the main plasma flow from the X5.16 flare has not yet reached Earth. If it had, it would mean speeds surpassing the famous 19th-century Carrington Event. The current intensification is likely caused by the interaction of plasma’s leading layers. The forecast for the next 24 hours remains uncertain: the second and third ejections are expected to approach and could either amplify or partially mitigate the impact on the magnetosphere.
In recent developments, advancements in satellite technology and predictive models have dramatically enhanced our ability to anticipate solar storm impacts. Researchers have produced cutting-edge algorithms capable of providing more accurate forecasts, allowing for better preparation on the ground. Yet, the current storm underscores the challenges in fully understanding these cosmic dances, reminiscent of historical events, that test the resilience of our technological systems.
