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.
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
A minor CME hit Earth’s magnetic field on October 31, 2012. This CME was generated by solar prominence on October 27/28. A Geomagnetic Sudden Impulse was detected at 15:39 UTC, indicating that geomagnetic storms are possible in the hours ahead, effecting very high
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
An M-class solar flare erupted on October 8, 2012 at 11:17 UTC. The event started at 11:05, peaked at 11:17 and ended at 11:23 UTC. The source of this flare is probably a new region on Sun’s northeastern limb rotating into Earth’s view. Coronal Mass Ejection (CME)
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
The September 28th Coronal Mass Ejection (CME) impacted Earth’s magnetic field at 22:20 UTC last night, September 30, 2012 sparking strong Geomagnetic storms at high latitudes today. The Bz component of the interplanetary magnetic field (IMF) sharply deviated to -35
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
