THE BIGGEST SOLAR FLARE OF THE CURRENT SOLAR CYCLE: Earth-orbiting satellites have just detected the most intense solar flare of the current solar cycle (so far)--an X8.7-category blast from giant sunspot AR3664. Extreme ultraviolet radiation from the flare ionized the top of Earth's atmosphere and caused a deep shortwave blackout over the Americas. As usual, https://Spaceweather.com is updating.
