The strongest geomagnetic storm in the past two months is expected to hit Earth, beginning on August 8.

Axar.az reports that a solar flare of the second-highest intensity class (M4.4) occurred on August 5. A plasma emission also took place, but the cloud was directed at about a 45-degree angle from Earth, not directly toward the planet. Scientists initially concluded that the event posed no threat to Earth. However, updated data suggests the geomagnetic impact on Earth will be much stronger than anticipated.

Specifically, Earth will be affected by the high-speed core of the cloud, delivering a strong blow to the planet’s magnetic field.

Forecasts indicate that the Kp geomagnetic index (which measures geomagnetic activity) will rise to level 6 — a level not seen since June 13.

Events of this scale are considered moderate in strength but can impact power systems, satellite operations, and radio signal transmission.

The worsening geomagnetic conditions are expected to begin Friday night, when Earth enters the influence zone of a large coronal hole. Overall, solar activity is considered intense, with 18 flares recorded on August 6 alone.
