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
The ACE Spacecraft detected a sudden solar wind increase to over 400 km/s at 04:30 UTC. A weak coronal mass ejection (CME) hit Earth’s magnetic field on Oct. 8th at approximately 05:00 UTC. 15 minutes after A Geomagnetic Sudden Impulse (21 nT) was registered.Low
A long duration B7.5 solar flare was observed at 07:30 UTC on October 5. Post eruption loop structures were observed in GOES SXI imagery in the vicinity of Region 1584. A partial halo CME was first observed in SOHO/LASCO C3 imagery at 07:30 UTC and STEREO Ahead
Sunspot 1583 on the western limb produced an M1.3 flare on Sept. 30 at 04:33 UTC. Region 1583 had grown rapidly in the past 24 hours, however it is only hours away from rotating off the solar disk and out of view. SIDC and NOAA/SWPC expect mostly eruptive conditions
Sunspot 1577 generated a long duration C3.7 solar flare which hurled a coronal mass ejection (CME) almost directly toward Earth on September 28. Proton levels reached the S1 Minor Radiation Storm level soon after the event. The proton event linked to the C3.7 flare
Solar activity was at low levels. The largest event during last 48 hours was a long duration C1 solar flare with a large prominence erupted on September 23 around 15:56 UTC from an area behind the eastern limb. It produces CME cloud with no threat to Earth.Some
