June 13, 2022: Growing sunspot AR3032 exploded on June 13th (0407 UT), producing an M3-class solar flare that lasted nearly 8 hours from beginning to end. NASA’s Solar Dynamics Observatory recorded the slow-motion blast:

Extreme ultraviolet radiation from the flare ionized the top of Earth’s atmosphere, causing a shortwave radio blackout over Japan and southeast Asia: blackout map. Radio operators in the area may have noticed unusual propagation effects at frequencies below 30 MHz for more than an hour after the flare’s peak.

Also, the explosion hurled a magnificent CME into space, according to coronagraphs onboard the Solar and Heliospheric Observatory (SOHO). Click to set the scene in motion:

NOAA analysts have determined that the CME will pass near Earth later this week, possibly delivering a glancing blow to our planet’s magnetosphere. Their simulation suggests an arrival time of 0900 UT on June 15th. Minor G1-class geomagnetic storms are likely if and when the CME makes contact. Solar flare alerts: SMS Text.
