THE "MARTIAN SUNSPOT" IS FACING EARTH: A sunspot big enough to see from Mars is now turning to face Earth. NASA's Perseverance rover on Mars first noticed the sprawling sunspot group last week, photographing it using the rover's MASTCAM. It was a behemoth then, and it has only grown bigger since. Here's how AR3576 looked yesterday from Argentina:  "The view was fantastic," says Eduardo Schaberger Poupeau, who photographed the sunspot using a solar-filtered telescope in the town of Rafaela. "AR3576 appeared as a large archipelago containing a multitude of dark cores." In fact, the sunspot is even bigger than the picture suggests. There's more of it visible in Poupeau's full frame image. From end to end, the sunspot group stretches more than 150,000 km with at least 4 dark cores larger than Earth. You can see it using ISO-approved eclipse glasses--no magnification required. AR3576 is big, yes, but of even greater interest is the sunspot's magnetic complexity. This magnetic map from NASA's Solar Dynamics Observatory shows a mixture of polarities in the sunspot's core:  In the circled region, positive and negative magnetic polarities are so closely-packed, you may need to look at this unlabeled map to see them clearly. Opposite polarities bumping together can cause explosive magnetic reconnection. Indeed, NOAA forecasters say this sunspot poses a threat for strong X-class solar flares-- and Earth is directly in the line of fire. Stay tuned |

Seems they have been watching it since August 2023? Here’s an interesting article https://www.space.com/solar-maximum-in-sight-but-scientists-will- have-to-wait-seven-months-after-it-occurs-to-officially-declare-it |

the Peltier effect coupling of one magnetic field with another magnetic field ... whenever there is charge there is a field associated with it |

the Peltier effect begins to loom large with this monster facing us ... theory is that a huge disturbance can couple with the magnetic field of the earth and cause a collapse of the field and immediate adiabatic cooling or perhaps a toppling of the earth |
