An impulsive solar flare measuring M7.3 at its peak time erupted from Region 2673 at 10:15 UTC on September 7, 2017. The event started at 10:11, peaked at 10:15 and ended at 10:18 UTC. It comes a day after two major X-class solar flares erupted from the same region….
The coronal mass ejection (CME) produced by the M5.5 solar flare on September 4, 2017 arrived at the DSCOVR spacecraft on September 6 at 23:08 UTC and at Earth 30 minutes later. The impact did not spark a geomagnetic storm, but the potential still exists as the CME…
A major X-class solar flare erupted from geoeffective Active Region 2673 peaking as X9.3 at 12:02 UTC on September 6, 2017. The event started at 11:53, peaked at 12:02 and ended at 12:10 UTC. This is the second X-class solar flare of the day. It comes just hours…
A powerful, long-duration solar flare measuring X2.2 at its peak time erupted from geoeffective Active Region 2673 at 09:10 UTC on September 6, 2017. The event started at 08:48 and ended at 09:59 UTC. This is the first X-class solar flare since May 5, 2015. There…
An asymmetric full halo Coronal Mass Ejection (CME) produced by the M5.5 solar flare at 20:33 UTC on September 4, 2017 is traveling toward Earth and is expected to arrive late on September 6. G3 – Strong geomagnetic storm watch is in effect for September 6 and 7….
Geoeffective Active Region 2673 produced 7 M-class and at least 8 C-class solar flares on September 4, 2017. The strongest was M5.5 at 20:33 UTC associated with an asymmetric full halo Coronal Mass Ejection (CME). This region has the potential to produce more strong…
A large and geoeffective Active Region 2673 (beta-gamma) unleashed a moderately strong M1.2 solar flare at 05:49 UTC on September 4, 2017. The event started at 05:36 and ended at 06:05 UTC. The region increased 10-fold in a single day, suddenly becoming one of the…
G2 – Moderate geomagnetic storm conditions were observed early August 22, 2017 due to a sudden enhancement in solar wind environment. SWPC said conditions are not expected to increase any higher, with solar winds continuing to decrease as the day progresses….
A moderately strong solar flare measuring M1.1 erupted from new Region 2672 (beta) at 01:52 UTC on August 20, 2017. The event started at 01:36 and ended at 02:03 UTC. Solar activity was at moderate levels on August 20 due to an M1 flare from an emerging region on…
Our planet is under the influence of a coronal hole high speed stream (CH HSS) which is causing isolated periods of G1 – Minor geomagnetic storming over the past 2 days, August 17 and 18, 2017. Meanwhile, solar activity is very low. There is only one numbered active…
