Solar activity ranged from low to high levels in last 7 days. Activity was low during October 15 – 19 due to mostly low-level C-class flares. The largest flare of this interval was a C7 on October 17, 2012 at 08:02 UTC from Region 1596 (N07, L=150, class/area
A moderate solar flare peaking at M1.38 erupted from emerging Region 1598 on October 21, 2012. This latest M-class eruption started at 19:46, peaked at 20:03 and ended at 20:20 UTC. Region 1598 was the source of yesterdays strong M9 solar flare and is moving into more
A strong solar flare reaching M9.0 took place at 18:14 UTC on October 20, 2012. Sunspot that produced it is rotating into view off the eastern limb. Associated was Type II Radio Emission. Estimated velocity was 516 km/s. Coronal mass ejection (CME) was associated but
Dozens of loops gyrated above several active regions as they were rotating into view (Oct. 13 – 17, 2012). When viewed in extreme ultraviolet light, the dancing loops of competing and connecting magnetic field lines become visible. Two minor eruptions can be observed
Sunspot region about to rotate into view off the southeast limb produced an M1.7 solar flare at 23:31 UTC on October 9, 2012. Just few hours later, at 5:04 UTC (October 10, 2012) the same region produced another M-class event peaking at M1.02. Geomagnetic
Earth remains under the influence of an October 5th coronal mass ejection (CME). Currently, G2 (Moderate) geomagnetic storm level (Kp=6) is in progress. At G2 level high-latitude power systems may experience voltage alarms, long-duration storms may cause
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
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
