The article has a part that seems incorrect. It says, "The cause of this issue was cosmic rays  —  charged particles that the sun emits during periods of high solar activity."

I've never heard that description of cosmic rays before. Those come from deep space. Charged particles from the sun are either the solar wind, a coronal mass ejection (CME) or a flare like an M or X-class flare. This July was the most active month of cycle 25 in terms of the sunspot number and the 10.7 cm Solar Flux. Saying the most active month in 20 years doesn't mean much since the last cycle was the weakest in 100 years.

Is the quoted line from the ESA or here?
