Long duration C3.7 solar flare erupted with Earth directed CME

A long duration C3 class solar flare erupted from Active Region 11577 peaking at 23:55 UTC September 27, 2012. The flare has produced a Coronal Mass Ejection (CME) which is expected to impact the Earth's magnetic field sometime late September 29, 2012. Proton levels

Solar prominence observed at eastern limb

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

Several strong solar flares and CME's seen at farside

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

Sun produced great solar filament eruption

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

Sunspot 1564 unleashed another solar flare reaching M1.2

Sunspot 1564 produced M1.2 solar flare at 22:36 UTC on September 9. It is not appeared to be Earth-directed.Another M class event was recorded day earlier. Sunspot 1564 produced an M1.4 long duration flare peaking at 17:59 UTC on September 8. CACTus reported

Two more M-class events from Region 1548 - M 1.8 and M 2.0

After today's strong M5.5 solar flare at 01:02 UTC another two moderate class solar flares erupted. On August 18, 2012 at 03:23 UTC new Active Region 1548 erupted with M1.8 solar flare followed by M2.0 at 16:27 UTC.More M-class events are expected from Region 1548.

New active region produced strong M5.5 solar flare

A new Active Region off the northeastern limb is really active and is crackling with M-class solar flares. Latest strong solar flare, reaching M5.5, occurred at 01:02 UTC on August 18. It did not produce Earth-directed CME.New active region is numbered as 1547

The second M-Class flare today around the new active region

The second M-class solar flare occurred today off the northeast limb at 17:20 UTC. It was measured as low-level M1.0 flare. The M1 flare was accompanied by a short duration Tenflare (10 cm Radio Burst) at levels of 140 sfu.  It is a second M-class solar  flare

Sun released long-duration C3 solar flare and CME

Solar activity was low for the last several days. Sunspot Region 1543 produced a long-duration C3 flare at 13:16 UTC on August 16. This flare was accompanied by Type II (704 km/s) and Type IV radio emissions and a coronal mass ejection (CME). Type II emissions occur
