Solar Activity

.24 hr Summary...
Solar activity peaked at high levels. Region 3006 (S30W07,
Eai/beta-gamma-delta) underwent overall decay, but despite its weakened
magnetic gauss strength, it became a bit more magnetically complex. This
instability was reflected with the eruption of an X1.5/1B (R3-Strong
radio blackout) at 10/1355 UTC. A weak geomagnetic crochet was also
noted in many day-side magnetometers and an EIT wave was observed in
GOES-16 SUVI/195A imagery.

Wow. That sounds wild even if I only understand the gist of it. Woa

Very cool! I see the analogy! love crocheting and seeing how simple loops and twists can change a fabric’s character with holes or elasticity. It’s cool to see this language used for sun magnetism.

Is a geomagnetic crochet a “twist” (alpha helix) or “loop” (omega) or both? This is to help me wrap my head around this alpha-omega dynamo concept.

I almost thought all sunspots had a “crochet loop” of some sort coming out of the areas of opposite polarity. Correct me if I’m wrong.
