GEOMAGNETIC STORM WATCH (G2): A CME launched into space by yesterday’s X5-class solar flare (see below) *does* have an Earth-directed component. According to a NASA model, it should strike our planet on Jan. 2nd. G2-class geomagnetic storms are possible when the CME arrives. CME impact alerts: SMS Text
MAJOR X-CLASS SOLAR FLARE: Mere hours after emerging over the sun’s eastern limb on Dec. 31st, big sunspot AR3536 erupted, producing a major X5-class solar flare. NASA’s Solar Dynamics Observatory (SDO) recorded the extreme ultraviolet flash:
This is the strongest flare of Solar Cycle 25 (so far) and the most powerful eruption the sun has produced since the great storms of Sept. 2017.
Radiation from the flare has caused a deep shortwave radio blackout over the Pacific Ocean: blackout map. Mariners and ham radio operators may have noticed loss of signal at all frequencies below 30 MHz for more than 60 minutes after the flare’s peak (2155 UT).
“Kuafu-1” successfully recorded the largest flare so far in the 25th solar cycle
