Partial, asymmetric halo CME expected to reach Earth late September 30 or early October 1

A partial, asymmetric halo coronal mass ejection (CME) was produced by C1.6 solar flare from Region 2871 at 06:34 UTC on September 28, 2021. Another, relatively weak CME was produced by the same region at 12:00 UTC on September 27, with glancing influence possible....

Filament eruption produces partial-halo CME, glancing blow expected

A solar filament eruption took place shortly before 12:00 UTC on February 20, 2021, producing a partial-halo CME. Analysis suggests a glancing blow from the periphery of the CME is likely on February 23 or 24. The CME signature was first observed in SOHO/LASCO C2...

Partial-halo CME impact sparks G1 geomagnetic storm

A partial-halo coronal mass ejection (CME) produced on June 28, 2017 hit Earth's magnetic field at 17:12 UTC on July 1, almost 24 hours earlier than expected. The impact was weak but managed to spark a G1 - Minor geomagnetic storm 17 hours later. G1 Watch...

Asymmetric, Earth-directed partial-halo CME and M1.0 solar flare erupted from Region 2497

An asymmetric partial-halo Coronal Mass Ejection (CME) erupted from Region 2497 late February 11, 2016. The CME was, at least in part, produced by a long duration C8.9 solar flare that peaked at 21:03 UTC. Associated with the event were Type II and Type IV radio...

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...
