Asymmetric full halo CME impact expected late May 11 into May 12

Asymmetric full halo CME impact expected late May 11 into May 12

An asymmetric full halo CME with a likely Earth-directed component erupted May 6, 2019. The source is still unknown, it is possible this was another stealth CME. Sun's northeastern limb continued exhibiting increased CME activity on May 6 and 7, 2019. This…

Partial-halo CME to deliver glancing blow on June 23

Partial-halo CME to deliver glancing blow on June 23

Filament eruption in the SSE quadrant of the Sun produced a partial-halo Coronal Mass Ejection (CME) first observed in coronagraph imagery near 08:45 UTC on June 19 (above). WSA-Enlil model suggests a glancing blow early on June 23. Beta-Gamma-Delta classified…

Huge solar filament facing Earth

Huge solar filament facing Earth

A huge solar filament is facing Earth today and, if it doesn't erupt, will continue to do so in the coming days. Stretched out, it would be more than 857 780 km or 533 000 miles long, which is more than 67 Earth diameters. Image below shows this filament as…

Sungrazing comet and farside full-halo CME

Sungrazing comet and farside full-halo CME

An icy comet with estimated size of few tens of meters plunged into the Sun on August 19/20, 2013 but just before it dissipated, a far-side region on the Sun expelled a magnificent full-halo CME.

Today's comet belonged to Kreutz Sungrazer family which

Full-halo Coronal Mass Ejection on farside of the Sun

Full-halo Coronal Mass Ejection on farside of the Sun

Region 1678 erupted with massive, full-halo, Coronal Mass Ejection around 04:00 UTC on March 5, 2013. The CME will have no effect on Earth as Region 1678 is on farside of the Sun. This old and active region is about to rotate onto the eastern limb by this

Full Halo CME + Proton Flare / Solar Watch Nov 27, 2011 (Video)

Full Halo CME / S1 Minor Radiation Storm:At 07:00 UT, a magnetic filament exploded in the northwest quadrant of the solar corona, causing a powerful Coronal Mass Ejection. Analysis of the Lasco C2 and in the latest STEREO Ahead/Behind COR2 images, it does appear
