Active Region 1618 keeps evolving and it has now Beta-Gamma-Delta magnetic configuration that harbors energy for M- and X-class eruptions. It produced an M3.5 flare with peak at 15:30 UTC on November 21, related to a halo CME first seen at 16:12 UTC by SOHO’s LASCO
Geomagnetic storm conditions are currently in progress in the wake of CME passage. A prolonged period of southward interplanetary magnetic field brought G2 (Moderate) Geomagnetic Storm conditions early on November 14 (UTC), evening hours November 13 (EST) according to
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.
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
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.
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
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
A weak CME shock was observed in the solar wind by the ACE and SOHO/CELIAS instruments on October 31st afternoon around 14:45 UTC. The solar wind speed jumped up from 280 km/s up to 370 km/s and also the solar wind density increased. Initial solar wind velocity had
Moderate solar activity has been observed during the past 24 hours. M2.3 solar flare was triggered by an Active Region behind the eastern limb around 11:17 UTC. Three C flares occurred during the day producing two CMEs, observed by LASCO C2/C3 coming off the east
