12. One of the reasons for closely monitoring the sun are its flares, CME, and EMP.

FTA:

"CHRISTMAS FLARE AND CME (UPDATED): Christmas began with a bang. At 0449 UT on Dec. 25th, active sunspot 3932 produced a strong M4.9-class solar flare. NOAA's GOES-16 satellite recorded the extreme ultraviolet flash above.

Soon after the flare, the USAF reported a Type II solar radio burst. This is a natural type of radio emission caused by shock waves inside CMEs. The drift rate of the Type II radio burst suggests that a CME will soon emerge from the blast site traveling a little faster than 1,000 km/s."

The sun's 11-year cycle:



On 1-2 Sep 1859, a massive solar flare spewed electrified gas and subatomic particles toward Earth, wreaking havoc on telegraph networks which became known as the "Carrington Event" (and the most intense solar storm in recorded history).


During this 1859 geo-magnetic solar cyclone, people reported "the sky was on fire."
