Major X1.5 solar flare erupts from Region 3386

A major solar flare measuring X1.5 erupted from the recently departed Active Region 3386 at 20:46 UTC on August 7, 2023. The event started at 20:30 and ended at 21:18 UTC.

A Type II Radio emission with an estimated velocity of 386 km/s was associated with the event, suggesting a coronal mass ejection (CME) was produced.

However, due to the location of this region, the CME is not expected to be Earth-directed.

Radio frequencies were forecast to be most degraded over the Pacific Ocean, Canada, the United States, and Central America.

Solar activity is expected to decrease to a chance for M-class flares on August 8 and 9 with the departure of Region 3386.

Periods of active geomagnetic field conditions are expected on August 7 due to the possible arrival of a CME from August 4. G1 – Minor storm levels are expected on August 8 due to a potential glancing blow from the combined August 5 CMEs.

Active conditions are expected again on August 9 due to residual CME effects and positive polarity CH HSS influences.
