A powerful solar flare of X2.7-class erupted from the sun on Tuesday, May 14, triggering strong radio blackouts across Europe, Asia, and the Middle East. The eruption, caused by a newly emerging sunspot region AR4087, sent a blast of X-rays and extreme ultraviolet radiation towards Earth at the speed of light.
The solar flare disrupted high-frequency radio signals, leading to communication dropouts for some radio operators in affected regions. While there may have been an associated coronal mass ejection (CME), its impact on our planet is yet to be confirmed.
However, as AR4087 rotates closer to Earth, the risk of more flares increases. If this activity continues, future eruptions could pack a punch to geomagnetic activity and aurora chances. The sun has been relatively quiet recently, but this X2.7 flare marks its return to high-level activity.
