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

Moderate solar flare - M1.6 peaked at 4:38 UTC Monday morning

After low solar activity the Sun erupted today with a moderate solar flare. This latest event started at 04:33 and peaked at 04:38 UTC Monday, August 6, 2012 with M1.6 solar flare. The source of this event was probably a new region now about to rotate into view off the

Region 1536 erupted with M1.1 solar flare

New Active Region 1536 erupted with moderate solar flare today. The event peaked at 15:48 UTC on July 30, 2012 measuring M1.1. This is first M-class solar flare from Region 1536.At 14:03 UTC today Region 1532 (S19E14) erupted with C8.8 flare. Analysis with

Sun unleashed M2.3 solar flare

Sunspot AR1532 is crackling with M-class solar flares. After strong M6.1 solar flare on July 28 at 20:56 UTC, it generated another M-class solar flare on July 29 at 06:22, this time measuring M2.3.The sunspot is still too far off the disk center to be very

Region 1520 sends another M-class solar flare - M7.7 not Earth directed

Region 1520 is still very active and located on the western limb. Latest event from this Sunspot started on July 19, 2012 at 05:13 and peaked at 5:58 UTC at M7.7. It looks like strong CME was released but since 1520 is located on the western limb it was not be Earth

Major, Earth directed and long duration X1.4 solar flare erupted from Sunspot 1520

A major and long duration solar flare peaked at 16:52 UTC on July 12, 2012. The source of this solar flare is Region 1520. A Type II and IV Sweep frequency events were recorded. Strong R3 radio blackout on the sunlit side of the Earth was recorded. This solar flare

Two new M-class flares and geomagnetic storming in progress

One of the largest Sunspots of the current cycle is rotating into position for Earth directed Solar Flares. Sunspot 1520 has a Beta-Gamma-Delta magnetic configuration and may produce an X-Class flare. M1.1 flare at 05:10 UTC was followed up with a M2.0 flare at 06:27

Strong solar flare reaching M6.9 took place at 16:32 UTC

Notorious Sunspot 1515 produced yet another strong M-class solar flare. This event started at 16:23 UTC on July 8, 2012, peaked 16:32 UTC at M6.9 and ended at 16:42 UTC. Sunspot 1515 is about to rotate to western limb so huge CME it has produced was not Earth

Welcome to active solar July! X-flare, geomagnetic storming, new sunspots

As expected, a giant sunspot AR1515 unleashed a strong X1.1 solar flare on July 6th at 23:08 UTC. This event triggered a 10cm Radio Burst and a Type IV Sweep Frequency Event. Preliminary analysis indicates the Coronal Mass Ejection (CME) associated with this event is

Strong solar activity continues - Minor geomagnetic storm possible

Another excitement day is over. Sunspot 1515 was very active today. It produced ten M-class solar flares backed up by ten more C-class flares.20gev_20120705_01052012/07/05 01:05:0001:15:0001:10:00M2.4S17W27 ( 1515 )21gev_20120705_02012012/07/05

Sun ain't giving us a rest - after series of M-class events an M6.1 peaked at 11:44 UTC

The Sun keeps producing M-class flares for second day in a row. We are now bound to get used to M-class same as we did with C-class. Yesterday we saw 5 strong M-class flares - today we reached that number before 8:00 UTC. The day is still not over and we have
