SOMETHING FLARE-Y THIS WAY COMES: A large and active sunspot group is about to rotate over the sun's northeastern limb. We can see it coming from the turmoil visible above the horizon:

It has already produced an M1-class solar flare (Sept. 30th at 0400 UT) partially eclipsed by the edge of the sun. The unobstructed flare was probably much stronger.
Helioseismologists have been tracking this sunspot group for more than a week. It is altering the way the whole sun vibrates, creating a dark echo in acoustic maps of the farside of the sun. Soon we will see it with our own eyes. The first dark cores should emerge this weekend.

🚨BIG SUNSPOT ALERT: One of the biggest sunspots in years is emerging over the sun's northeastern limb. AR3112 has more than a dozen dark cores scattered across 130,000 km of solar terrain, making it an easy target for backyard telescopes using the projection method. Magnetograms of the sunspot group reveal a delta-class magnetic field that harbors energy for X-class solar flares https://www.spaceweather.com/images2022/02oct22/newspot_crop_strip_opt.gif

HIGH SOLAR ACTIVITY: The sun just strobed Earth with a pair of strong M-class solar flares. In quick succession on Oct. 1st and 2nd, NASA's Solar Dynamics Observatory recorded flashes of extreme ultraviolet radiation: https://www.spaceweather.com/images2022/02oct22/doublem_teal_crop_strip.gif
Radiation from the flares ionized the top of Earth's atmosphere, causing shortwave radio blackouts over the Pacific side of North America and later Australasia. Ham radio operators, aviators and mariners may have noticed fadeouts and other unusual propagation effects at frequencies below 20 MHz.
These flares registered M5.9 and M8.7, the second explosion only decimal points away from being an X-flare. If this progression continues, an X-flare could occur before the weekend is over.

🚨MULTIPLE CMES ARE COMING: NOAA forecasters say there is a chance of G2-class geomagnetic storms on Oct. 4th when multiple CMEs might sideswipe Earth's magnetic field. Most of the incoming CMEs were hurled into space by sunspot AR3110, which unleashed a series of strong flares (M5.9, M8.7, X1) over the weekend. During G2-class storms, naked-eye auroras can descend into the United States as low as New York and Idaho.

A BIG DANGEROUS SUNSPOT: One of the biggest sunspots in years has just rotated over the sun's northeastern limb. Introducing, AR3112.
AR3112 has more than a dozen dark cores scattered across 130,000 km of solar terrain, making it an easy target for backyard solar telescopes. Don't have a solar filter? Use the projection method, instead.
The image above is a magnetic map of the sun's surface with a white light photo of AR3112 inset. It shows what makes this sunspot group so dangerous. Positive and negative magnetic polarities are bumping together--an explosive mixture that could produce an X-class solar flare.
The emergence of AR3112 already fully formed and unstable could herald two weeks of high solar activity as the sunspot group transits the solar disk, facing Earth the whole time. Stay tuned.
