Solar filament eruption sent Earth-directed CME

A Coronal Mass Ejection (CME) was observed on November 9, around 15:24 UTC. It was associated with  filament eruption around sunspot 1608 in the southeast quadrant of the disk. This region is facing  Earth and any  Coronal Mass Ejection (CME) may be geoeffective.

Sun hurled two bright CMEs into space, both non-Earthbound

New region 1611 rotated into view on the east limb and produced a moderate M1.7 flare at 02:23 UTC and a type II radio sweep shortly after, on November 8, 2012. Flare generated bright coronal mass ejection (CME) in eastward direction which means that it would not

STEREO satellites recorded 8 CME's over two-day period

The Sun produced a series of at least eight coronal mass ejections (CMEs) over a two-day period (November, 2-4, 2012). Some of them overlapped each other as the Sun burst some of them into space in a rapid-fire style. The series was taken by the STEREO Ahead spacecraft

Magnetic filament eruption took place beyond the western limb, producing a halo or partial-halo CME on November 3. In fact, three CME clouds were ejected into space, with one appeared to have slight chance to become geoeffective. Minor solar wind stream from
