Sun activity: Bam! Beautiful filament eruption

The sun, seen as a yellow sphere with dark spots.

A beautifully structured filament erupted at 18:43 UTC (July 23, 2022) from the southwest limb (edge) of the sun. It produced a bright coronal mass ejection (CME), observed in the SOHO/LASCO coronagraphs.

Sun activity remains low, with 16 C class flares. The highest, a C3.6, occurred at 22:41 UTC on July 23. The sun has six labeled active regions. On the Next 24 hours: The flare forecast is 55% chance for C flares, 5% for M flares, and 1% for X flares. Next expected CME: There might be an Earth-directed CME from the July 23 filament eruption. We’ll know more when the analysis is complete.

Coronal Mass Ejections (CMEs) are large expulsions of plasma and magnetic field from the Sun’s corona. They can eject billions of tons of coronal material and carry an embedded magnetic field (frozen in flux) that is stronger than the background solar wind interplanetary magnetic field (IMF) strength.

What does a CME do to Earth?
 If Earth happens to be in the path of a CME, the charged particles can slam into our atmosphere, disrupt satellites in orbit and even cause them to fail, and bathe high-flying airplanes with radiation. They can disrupt telecommunications and navigation systems.

As predicted, beautiful auroral displays have been seen as far south as Ohio and Minnesota since late last night of  (July 22, 2022) and into this morning. They are the result of a CME impact, which sparked a G1 (minor) geomagnetic storm, whose threshold was reached at 3:59 UTC on July 23. As of this writing (11:30 UTC on July 23, or 6:30 a.m. CDT), a G2 (moderate) geomagnetic storm is possible in the hours ahead.
