Earth Directed M8.4-Class solar flare – CME
One Two Punch: In the evening hours of March 10th, starting at around 15.52 UT, sunspots 1430 and 1429, unleashed a double blast. 1430 started the show with a C8.0-class sloar flare and CME. Then 1429 followed up with a much stronger blast. An M8.4-class solar flare at around 17.44 UT. The powerful M8-class flare that almost crossed the threshold into X-territory.
A CME launched from the sun on March 9th is nearing Earth. According to analysts at the Goddard Space Weather Lab, the cloud will arrive on March 11th at 0649 UT (+/- 7 hr).
During the flare, New Mexico amateur astronomer Thomas Ashcraft recorded a series of radio bursts at 21 and 28 MHz:
Listen to the Roaring Sounds ‘Sounds Familiar’?
The roaring sounds you just heard are caused by shock waves plowing through the sun’s atmosphere in the aftermath of the explosion.
The cloud will hit our planet’s magnetosphere on March 12th at 1803 UT (+/- 7 hr)
Although the magnetosphere is calm now, more storms arre in the offing. A CME hurled toward our planet by the M6-class solar flare of March 9th is expected to reach Earth during the early hours of March 11th.
