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
The video by Solar Dynamics Observatory (SDO) combines three wavelengths with similar temperatures, highlighting different parts of the solar corona showing the Sun from September 1 through September 30, 2012. The start of the Fall Eclipse Season could be seen, when
Solar activity was at low levels for the past 24 hours and X-Ray flux plot shown merely C-class threshold. However, a prominence eruption was observed north of Region 1600.A bright CME was observed in STEREO Ahead COR 2 imagery at 18:24 UTC on October 27. Latest
X1.8 solar flare peaked at 03:17 UTC on October 23, 2012 around Active Region 1598, which is still several days away from directly facing Earth from center disk. NOAA/SWPC forecasters estimated 20% chance for another X-class event.Space Weather Message Code:
A moderate solar flare reaching M5.06 took place at 18:51 UTC on October 22, 2012. The responsible Region was again 1598. The event started at 18:38, peaked at 18:51 and ended at 19:01 UTC.Space Weather Message Code: SUMXM5Serial Number: 99Issue Time: 2012 Oct 22
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
