Sol (Sun) and its phenomena

Following yesterday's flare the same sunspot produced the second largest flare of the current cycle, look's like a hit for the C's last session statement : "Explosive revelations and events coming!" :halo:

SIGNIFICANT X-CLASS SOLAR FLARE: Fast-growing sunspot AR3842 erupted on Oct 1st (2220 UT), producing the second-strongest solar flare of Solar Cycle 25. The X7.1-category blast caused a shortwave radio blackout over Hawaii and hurled a CME into space. A preliminary NASA model predicts it will hit Earth on Oct. 5th. Stay tuned for the geomagnetic storm forecast. Solar flare alerts: SMS Text

October 3 UPDATE: BAM, X9 flare! Largest of the solar cycle so far​


At 12:10 UTC today, shortly after the cut-off for our daily sun update, the sun blasted an X9 flare: the biggest flare of Solar Cycle 25 so far. It came from sunspot region AR3842, which fired an X7 flare on Tuesday. This region is currently near the center of the solar disk, so any sun-stuff ejected during this flare would likely be on a course for Earth. Stay tuned.


 
The sun remains active, two more X flares, on the 7th an X2 and early this morning anther long duration X1.8 wich trigered a proton event :

BIG X-CLASS SOLAR FLARE: Sunspot AR3848 was directly facing Earth this morning, Oct. 8th (0156 UTC), when it unleashed a powerful X1.8-class solar flare. NASA's Solar Dynamics Observatory recorded the extreme ultraviolet flash:​




This explosions lasted more than 4 hours, so long that it lifted a massive CME out of the sun's atmosphere. Take a look at these preliminary coronagraph images from NASA's STEREO-A spacecraft. This CME will certainly hit Earth later this week, potentially sparking a new round of geomagnetic storms.​
