Solar flare and Earth-directed CME

SOLAR FLARE AND CME: Big sunspot AR2473 erupted on Dec. 28th, producing an M1.9-class solar flare, a minor radio blackout in the southern hemisphere, and a coronal mass ejection (CME) that appears to be heading directly for Earth.  This explosion sets the stage for possible geomagnetic storms later this week when the CME reaches our planet.  Visit Spaceweather.com for more information.

POLAR STRATOSPHERIC CLOUDS: For the second time this month, Arctic sky watchers are reporting a rare outbreak of super-colorful polar stratospheric clouds (PSCs).  Photos and observing tips are featured on today's edition of Spaceweather.com

Growing Sunspot Crackles with Flares

CHRISTMAS FLARES:  A new sunspot (AR2473) is growing rapidly in the sun's southern hemisphere, more than quadrupling in size in the past 24 hours. Crackling with M-class solar flares, the sunspot has already caused several minor shortwave radio blackouts, mainly south of our planet's equator. More flares and radio blackouts are in the offing as the growing sunspot turns toward Earth. Visit http://spaceweather.com for more information.

X2-class Solar Flare Causes Radio Blackout

X-FLARE: Emerging sunspot AR2339 unleashed an intense X2-class solar flare on May 5th at approximately 22:11 UT.  Radiation from the flare caused strong radio blackouts on the Pacific side of Earth, interfering with communications at frequencies below ~20 MHz.  The blast also hurled a CME into space, but not toward Earth. This event could herald a sustained period of high solar activity, as AR2339 appears to be large and explosive.

EARTH DIRECTED X-FLARE: On March 11th at approximately 16:22 UT (09:22 PDT) sunspot AR2297 unleashed a strong X2-class solar flare. Extreme UV radiation from the blast is causing HF radio fade-outs and other propagation effects on the dayside of Earth, primarily over the Americas.
