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

Geomagnetic storm in progress!

Geomagnetic K-index of 5 alert is issued by Space Weather Prediction Center. Kp-indices of 5 or greater indicate storm-level geomagnetic activity. Geomagnetic storms have been associated with satellite surface charging and increased atmospheric drag.Speed of solar

Unbelievable events in Antarctica

We only believe what we see with our own eyes and then even then, if we do not want to see something, we will not see it even if it’s there. Lately, I have been taking virtual journeys down to the Antarctic Circle to the Neumayer Station, which has a 24/7...

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

First Trojan asteroid found locked into Earth's orbit

NASA’s Wide-field Infrared Survey Explorer (WISE) has found the very first asteroid that (more or less) shares an orbit with Earth! Called 2010 TK7, this asteroid is about 300 meters (roughly 1000 feet) across, and is the first in an up-to-now theoretical class of

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
