Strong solar activity - M9.3 solar flare took place, expecting CMEs

Sunspot 1261 is at it again, this time producing a strong M9.3 Solar Flare at 03:57 UTC Thursday morning. It also turns out that yet another Coronal Mass Ejection (CME) was produced and you can see it in the still image below captured by STEREO Ahead.Proton Levels are o

A moderate solar flare reaching M6.0 took place around Sunspot 1261

A Moderate Solar Flare reaching M6.0 took place around Sunspot 1261 at 13:47 UTC Wednesday and appears to be long in duration. A brief R2 Radio Blackout resulted. A bright Coronal Mass Ejection (CME) is associated and can be seen in the image below. It is most likely

Sunspots 1261 and 1263 produce pair of M-Class flares - Expecting geomagnetic storm

An M1.1 Solar Flare took place around Sunspot 1261 at 03:37 UTC Wednesday morning followed an hour later by a M1.7 flare around Sunspot 1263 at 04:32 UTC. Stay tuned to this website for any further developments.A long duration M1.4 Solar Flare took place around

Massive double Sunspot 1263 - wider than the Earth - harbors energy for powerful X-class solar flares!

Double sunspot 1263 is a whopper. Its two dark cores are each wider than Earth, and the entire region stretches more than 65,000 km from end to end. The clarity of  image is impressive. Note the granulation of the stellar surface surrounding the main dark cores.

M1.4 Earth-directed solar flare took place

Magnetic fields above sunspot 1261 erupted this morning at 0648 UT, producing an M1-class solar flare. The blast also hurled a bright coronal mass ejection toward Earth. This movie from the STEREO-Ahead spacecraft shows the cloud racing away from the sun at almost

A strong M9.3 solar flare took place

Sunspot AR1261 unleashed a brief but strong M9-class solar flare on July 30th at 0209 UT. NASA's Solar Dynamics Observatory recorded the flare's extreme ultraviolet flash:Because of its brevity, the eruption probably did not hurl a substantial CME toward Earth,

Sun harbors energy for powerful X-class solar flares

Sunspot 1260 has developed a delta-class magnetic field that harbors energy for powerful X-class solar flares. Such an eruption today would be Earth-directed as the sunspot turns to face our planet.Sunspot 1260 is leading a parade of big sunspots across the solar

Incoming Coronal Mass Ejection (CME)

During the early hours of July 9th, a Coronal Mass Ejection (CME) billowed away from new sunspot 1247. A preliminary analysis of data from NASA's twin STEREO-A and -B spacecraft suggests that the flank of the CME could hit Earth's magnetic field sometime on July
