The underlying sunspot is a giant, and it is turning toward Earth with more flares expected.
The biggest firework imaginable, 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 exploded on New Year's Eve, just after 24:00 hours (Israeli time) Signs And Wonders?
According to Spaceweather.com just a few 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 recorded the extreme ultraviolet flash. The explosion caused a solar tsunami. This is the strongest flare of Solar Cycle 25 (so far). Radiation from the flare has caused a deep shortwave radio blackout over the Pacific Ocean. It's too soon to know for sure, but this explosion probably launched a coronal mass ejection (CME) into space. Because the blast site is located near the extreme eastern edge of the sun, the CME is unlikely to have a significant Earth-directed component.

NASA was somewhat caught out and predicted a 0.1% chance of an X-class flare earlier today—Stay tuned!
