AFP-Jiji WASHINGTON (AFP-Jiji) — Two high-intensity solar flares were emitted Wednesday, the second of which was the most intense recorded since the start of this sun cycle in December 2008, the U.S. National Aeronautics and Space Administration said.
These radiation flares, which can disrupt communications satellites, GPS and power grids by reaching the upper Earth atmosphere, were detected and captured by the Solar Dynamics Observatory.
According to the Space Weather Prediction Center, these so-called category X eruptions disrupted high-frequency radio communications for one hour on the Earth’s side facing the sun and low-frequency communications used in navigation.
The two eruptions occurred in an active region of the sun where an eruption of average intensity occurred on Monday. The current cycle of the sun, which began in December 2008, saw the intensity of solar activity decline sharply, opening the way to the “solar minimum.”
