January 15, 2013 – THE SUN – Simulations of a coronal mass ejection (CME) show the impact arrival of such on January 17th. This coincides with Senior Meteorologist Kevin Martin’s window for an earthquake in North America. The Sun is acting up again, with large sunspots moving across the solar disk. The sunspots are powerful enough for x-class solar flares, the most powerful of them all.

While a 10% chance is now given for such a flare, one is already on the way. This should impact on January 17th and Read more…
This view of the flare on Jan. 11, 2013, was recorded by NASA’s Solar Dynamics Observatory.
The surface of the sun erupted in a solar flare early today (Jan. 11), unleashing a blast of super-heated plasma into space.
A huge sunspot known as AR1654 produced the M1-class flare at 4:11 a.m. EST (0911 GMT), officials with NASA’s Solar Dynamics Observatory said in a description of the event. The SDO spacecraft is one of several sun-watching space telescopes keeping tabs on solar flares and other sun weather events.
According to Spaceweather.com, sunspot AR1654 is growing more active and is now “crackling with M-class solar flares” like the one that erupted today.

BIG SUNSPOT: One of the largest sunspot groups in years rotated over the sun’s northeastern limb this weekend. With a least four dark cores larger than Earth, AR1476 sprawls more than 100,000 km from end to end, and makes an easy target for backyard solar telescopes. Amateur astronomer Alan Friedman sends this picture of the behemoth from his backyard in Buffalo, NY: “AR1476 is firecrackler,” says Friedman. Indeed, the active region is crackling with impulsive M-class solar flares. Based on the sunspot’s complex ‘beta-gamma’ magnetic field, NOAA forecasters estimate a 75% chance of Read more…
