While Earth expects CME impact, Sunspot 1613 produced M2.0 solar flare

Active region 1613 produced M2.0 solar flare at 23:28 UTC on November 12, 2012. This expanding region is rotating into direct Earth-view position and may produce more activity. Sunspots 1610, 1611 and 1614 are currently the largest sunspots on the visible solar disk.

Sun produced spectacular plasma prominence and backsided M1.0 flare

Solar activity is moderate. Three C-class events were observed overnight and giant plasma filled prominence occurred on the southwest limb. M1.0 solar flare was registered around 02:11 UTC but it was not associated with numbered active region. Amazing plasma filled

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

M1.7 solar flare erupted from Region 1611 - backsided full-halo CME observed

Solar flare measuring M1.7 erupted on November 8, 2012 at 02:23 UTC. The source of this event is newly formed region rotating into view, Region 1611 (N12E66). The event started at 02:28, peaked at 02:23 and ended at 02:25 UTC. Type II Radio Emission was recorded

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
