Satellites in Earth orbit have detected a solar flare whose strength experts estimate to be class X.
This is the latest in a series of distant explosions that began earlier this week. The site of the explosion is just beyond the northeast limb of the Sun, possibly an unstable group of sunspots. It has been hurling outbursts over the edge of the sun all week .
Although this flare was a distant event, it did touch Earth. The pulse of X-rays ionized Earth’s upper atmosphere and caused shortwave radio over Australia to shut down.
Pilots, sailors, and radio amateurs could notice unusual effects propagating on frequencies below 25 MHz.
The source of this activity will turn to face Earth this weekend.
