Epic Solar Filament Eruption from Dec. 6, 2010 Seen by STEREO

A very long solar filament that had been snaking around the Sun erupted (Dec. 6, 2010) with a flourish. STEREO (Behind) caught the action in dramatic detail in extreme ultraviolet light of Helium. It had been almost a million km […]

Increased Auroral Activity Oct. 11-12 from a Halo CME Oct. 6, 2010

Around 3:30 UT on October 6, 2010 a filament erupted in the northeast part of the solar disk (upper left area). Moving at around 375 km/s (850,000 miles per hour) the CME combined with the ambient solar wind then over […]

A Solar Eruption as the Earth Blocks SDO’s View of the Sun

A filament erupted in the NE area of the sun. The eruption was observed by SDO and the associated Halo CME was seen by SOHO's C2 and C3 coronagraphs. SDO is currently in eclipse season so during this event the earth moved between SDO and the sun, moving across the sun for a few minutes.

3D Visualization of a Coronal Mass Ejection

Our good friends and colleagues at Trinity College Dublin have created a 3D visualization of the propagation of a coronal mass ejection (CME). Using multiscale image processing and 3D visualization the team reconstructed the trajectory of an earth-directed CME observed […]
