Solar filament eruption, possible glancing blow on November 29

A solar filament was observed lifting off the Sun's northeastern quadrant beginning at approximately 04:45 UTC on November 25, 2017. An associated weak Coronal Mass Ejection (CME) was observed in SOHO/LASCO C2 and C3 imagery and the analysis shows a potential...

Filament eruption, glancing blow possible on April 15

An approximate 14 degree solar filament eruption began at 20:25 UTC on April 9, 2017, from the northeast quadrant of the Sun. The event generated a coronal mass ejection (CME) and a glancing blow is possible on April 15. The CME was first observed in SOHO/LASCO C2...

G2 geomagnetic storm in progress, G3 - Strong watch in effect for October 14

A filament in Sun's northeast quadrant erupted between 15:00 and 17:00 UTC on Saturday, October 8, 2016, producing an asymmetric, partial-halo CME. The CME, although faint, was first observed in LASCO C2 imagery beginning 00:48 UTC on October 9. It reached ACE...

Large filament erupts on the southeast quadrant of the Sun

A large filament erupted on the southeast quadrant of the Sun during the early morning UTC hours of November 22, 2015. The eruption began at approximately 07:30 UTC and launched a coronal mass ejection (CME) into space. Although LASCO coronagraph imagery is still...

CME hits Earth sparking geomagnetic storm

Two solar filaments erupted from the SW quadrant of the Sun late November 15 and early November 16 producing a Coronal Mass Ejections (CMEs) that arrived at Earth at 20:10 UTC on November 18. A G1 - Minor geomagnetic storm is currently in progress. This, combined...

Filament eruptions and impulsive M1.5 solar flare, geomagnetic storming expected due to CH HSS

Moderately strong solar flare reaching M1.5 at its peak time erupted at 12:53 UTC on July 3, 2015. The event started at 12:47 and ended at 12:53 UTC.The source was Region 2378, which rotated into the southwest quadrant yesterday producing innumerous C-class solar flares

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 Region

Several eruptive filament structures observed in last 24 hours

Several eruptive filament structures occurred during last 24 hours as observed in SDO/AIA and GONG/H-alpha imagery.The most impressive was an eruptive prominence (EPL) from the NE limb and a connected highly active and partially eruptive filament from the NE quadrant.

Filament eruption produces CME off the west limb, proton spike

A solar filament/prominence was observed leaving the west limb of the Sun around 02:20 UTC today resulting in a Coronal Mass Ejection (CME). Although this CME has a trajectory which is away from the Sun - Earth line, and despite its relatively slow velocity, there was a

Large solar filament erupts from the northeast quadrant

A large solar filament located in the northeast quadrant erupted around 14:00 UTC on April 28, 2015 sending a bright Coronal Mass Ejection (CME) into space.CME is visible in latest SOHO LASCO C2 imagery and it appears directed away from our planet.Image credit: ESA/NASA

Large solar filament erupts, produces partial halo CME

A large solar filament, which was stretching more than 857 780 km (533 000 miles) last week, finally erupted at approximately 09:25 UTC on February 21, 2015. As I feared, #solarstorm launch is huge filament that just rotated backside. STEREO A saw eruption of monster ev

Filament eruption creates canyon of fire, Earth directed CME

Solar filament located in the southern hemisphere erupted at approximately 16:54 UTC on August 15, 2014, and launched a partial-halo Coronal Mass Ejection (CME) into space and toward our planet. NSO/GONG and SDO/AIA 193 and 304 imagery observed major portions of a
