First solar activity in 2012 - Ionospheric disturbance and wonderful auroras

Polar Light Center in Lofoten, Norway recorded today around 13:20 UTC, a wave of ionization that swept through the high atmosphere over Europe after sunspot AR 1389 unleashed another M2-class solar flare. NOAA/SWPC forecasters estimate a 40% chance of more M-flares

Another Venus-directed CME

A magnetic prominence dancing along the sun's southeastern limb became unstable on Nov. 15th and slowly erupted. NASA's Solar Dynamics Observatory recorded the coronal mass ejection (CME), which unfolded over a period of thirteen hours: The eruption hurled a cloud

Incoming coronal mass ejection

As predicted by analysts at the Goddard Space Weather Lab, a coronal mass ejection (CME) hit Earth's magnetic field at ~03:30 UT on Sept 17th. The impact was not strong. Nevertheless, the arrival of the CME could spark geomagnetic activity around the Arctic Circle.

Farside CME activity continues

Solar Activity continues at fairly low levels with only C-Class activity taking place in the past 24 hours. Sunspot 1271 is the largest visible area and it may pose a small threat for an M-Class event.Farside CME activity continues and you can view all of the action

New sunspots forming, Venus-directed CME

Yesterday, the Solar and Heliospheric Observatory witnessed a spectacular explosion on the sun that seemed to pass perilously close to Venus.As the movie shows, the CME passed harmlessly. There was no collision, and it wasn't even close. Although Venus seems to be

A huge filament of magnetism and hot plasma blasted off the sun's southwestern limb

A huge filament of magnetism and hot plasma blasted off the sun's southwestern limb on March 19th around 1200 UT. The eruption was not Earth-directed, but it did attract plenty of attention on our planet. Many amateur astronomers in Europe witnessed the blast and said
