Increased solar activity after strongest solar radiation storm since 2006

Growing Sunspot 1402 erupted in morning of January 23, 2012 around 04:00 UTC, producing a long-duration M8.7 solar flare. Each category for x-ray flares (B,C,M,X) has nine subdivisions ranging from  C1 to C9, M1 to M9, and X1 to X9. This one ranks M9, which is only

A strong solar flare reaching M8.7 took place at 03:59 UTC Monday morning

A strong solar flare reaching M8.7 was generated by Sunspot 1402 in the northern hemisphere. The flare peaked at 03:59 UTC monday morning (Jan 23 2012) and started off an a long duration M1.0 event (LDE) before eventually rising again to its maximum. An R2 Radio

CME impact strongly compressed Earth's magnetic field and produced auroras

A coronal mass ejection (CME) hit Earth's magnetic field at 06:17 UTC on January 23, 2012 and produce geomagnetic storm (Kp5/G1 Level geomagnetic storm is currently in progress) and ongoing auroras around polar cycle. According to analysts at the Goddard Space Weather

Geomagnetic storm in progress!

A solar wind stream is buffeting Earth’s magnetic field and this is causing geomagnetic storm. A coronal mass ejection (CME) The Coronal Mass Ejection (CME) reported on Jan 19, finally impacted our geomagnetic field with a glancing blow early this morning.hit

CME will likely pass above Earth's north side on Jan 22, auroras expected

NOAA/SWPC have determined that the CME from Active Region 1402 near disk center from the latest M3 solar flare will likely pass above (north) of Earth. This glancing blow will cause just G1 (Minor) Geomagnetic Storm activity. We can expect first signs  starting from

M3.2 solar blast from Sunspot 1402 produced Earth-directed CME

The long-duration blast at active region 1402 produced M3.2 solar flare and CME which is heading toward Earth. This was two-wave flare and first CME wave was overtaken by the 2nd wave due to its higher speed velocity.The major bulk of the plasma cloud appears to be

Solar activity increasing - M-class flares, auroras and magnetic filaments

Recently formed sunspot 1401 awoke yesterday afternoon and produced an M1.7 solar flare at 19:12 UTC. AR 1401 has a Beta-Gamma magnetic configuration which could lead to further solar flares. NOAA forecasters estimate a 15% to 20% chance of polar geomagnetic storms

New sunspot regions turning earthwards

A very long in duration C6.4 event was detected around Sunspot 1402 in the northeast quadrant. A Coronal Mass Ejection (CME) was produced, but is directed to the north and east. Most of the magnetic activity in this event appears to be above the actual

Solar wind stream blowing from big coronal hole, new sunspot regions forming

The dark vertical coronal hole, about 120,000 km wide and more than a million km long, stretches in the center of the Sun. A solar wind stream flowing from the indicated coronal hole should reach Earth on Jan. 16-17, possibly sparking auroras at

A long-duration C3 solar flare at the Sun's farside

NASA's STEREO-Behind spacecraft observed a significant eruption on the farside of the sun today. Although the blast was eclipsed by the edge of the solar disk, it nevertheless produced a long-duration  C3 solar flare detectable from Earth. The blast site is not far

Recent solar activity

Sunspot 1393 is growing rapidly, more than tripling in area since Friday. So far, however, the active region has not produced any strong flares. Solar activity remains low.Solar activity increased somewhat, with a solar flare detected around Sunspot 1386 off the

Eruption on farside solar western limb

Sunspot 1384, currently located just behind the sun's western limb, erupted today around 14:45 UTC. It registered as a long duration C2.4 flare and it appears to be connected to magnetic filaments snaking over the horizon to the Earthside of the sun. This event

First solar activity in 2012 - Ionospheric disturbance and wonderful auroras

Polar Light Center in Lofoten, Norway recorded today around 13:20 UTC, a wave of ionization that swept through the high atmosphere over Europe after sunspot AR 1389 unleashed another M2-class solar flare. NOAA/SWPC forecasters estimate a 40% chance of more M-flares

Another two M-class solar flares occur today, Sunspot 1389 turning earthwards

Emerging over the sun's southeastern limb, sunspot AR1389 unleashed two M-class solar flares on Dec. 29th. A moderate M2.0 solar flare occur at 21:51 UTC Thursday evening and a moderate M1.9 Solar Flare this morning at 13:50 UTC. The blasts show  that the

New large sunspot rotating Earthward on the eastern limb

A new large sunspot is now rotating into view on the eastern limb. It just produced a minor C6.7 Solar Flare at 22:26 UTC Tuesday evening. Solar activity was moderate on Monday with one M-Class flare detected around Sunspot 1387. Numerous C-Class events were

Solar activity heightens up: 3 M-class flares and 11 C-class flares in past two days

An M-Class flare with a double peak took place this afternoon at 20:30 UTC around active Sunspot 1387. The flare measured M2.3 and was captured by SDO in the image below. A long duration C5.7 Solar Flare was detected around Sunspot 1384 this morning (Dec 26) and
