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
At least three large CME clouds were observed during last 24 hours but all of them were at far side so there is no danger for Earth, they are heading away from our planet. Old Sunspot 1564 was probably source of the flares. STEREO Behind COR2 recorded bright flash with
Solar activity is expected to be low with a slight chance for M-class flares for the next three days, mainly from Region 1569. NOAA/SWPC estimates 20% chances of M-class solar flare. Region 1564 is crackling with C-class flares.The geomagnetic field was mostly quiet
Anyone who observes solar activity here and there surely noticed spectacular solar filament on August 31, 2012. We saw amazing images presented to us by solar observatories in space and now SOHO combined all recordings from EUVI, COR1, COR2 and HI1 that give us clear
Geomagnetic storming reached the G2 (Moderate) level at high latitudes again early today. Bright auroras could be seen around Arctic Circle. It was sparked by one of two coronal mass ejections observed on September 2. Solar radiation storm levels have returned to
NOAA/SWPC reported that the G1 (minor) Geomagnetic Storm has ended with the return of normal solar wind conditions. Currently solar winds blow at speed of 419.1 km/sec. Earthbound proton levels are now below the S1 Minor Radiation Storm threshold and geomagnetic
Solar filament eruption on August 31 generated at least two potentially Earth directed CME clouds. Earth was hit by first CME shock, observed in the solar wind around 11:20 UTC. The impact induced significant ground currents in northern Scandinavia and
The Coronal Mass Ejection was caused by the large filament eruption late on August 31st. Minor to Moderate Geomagnetic Storming will be possible at high latitudes, especially on September 3rd. Solar Radiation Storm levels have increased above the S1 (Minor)
