<br>
The Space Weather site reports sunspot complex AR2565-AR2567 erupted<br>
on July 23, twice, producing two strong solar flares in quick<br>
succession<br>
<br>
The first at 0211 UT registered M5 on the Richter Scale of Flares.<br>
The second at 0516 UT registered M7.6, making it the strongest flare<br>
of 2016 so far.<br>
<br>
Pulses of radiation from the two flares ionized the top of Earth's<br>
atmosphere, causing a blackout of shortwave radio transmissions over<br>
the Pacific side of Earth. People who might have noticed the fading<br>
signals include ham radio operators, mariners and aviators.<br>
<br>
The explosions hurled an impressive CME into space. The body of the<br>
cloud will not hit Earth. However, Earth could experience a glancing<br>
blow from shock waves on the outskirts of the cloud. This has prompted<br>
NOAA forecasters to issue a minor geomagnetic storm warning for July<br>
26.<br>
