A BIG DANGEROUS SUNSPOT
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. Aurora alerts: SMS Text
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. Solar flare alerts: SMS Text
