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…
A pair of solar flares erupted near the eastern limb of the Sun at about 00:55 and 03:25 UTC on July 23, 2017, and were observed in STEREO-A EUVI 195 imagery. The source is Active Region 2665 which produced a long-duration M2.4 solar flare and Earth-directed CME on…
A positive polarity coronal hole high speed stream (CH HSS) is affecting our planet and will continue to do so over the next three days. Over the past 24 hours, by 12:30 UTC on July 22, solar wind parameters as measured by DSCOVR spacecraft reflected the influence…
A coronal mass ejection (CME) produced by the July 14th M2.4 long-duration solar flare hit Earth's magnetic field at 06:01 UTC on July 16, 2017. G2 – Moderate geomagnetic storming started 9 hours later. The S1 Minor solar radiation storm that started at 09:00…
Active Region 2665 produced a long-duration solar flare measuring M2.4 at its peak time on July 14, 2017. The event lasted for more than 2 hours; it started at 01:07, peaked at 02:09 and ended at 03:24 UTC. The eruption produced a coronal mass ejection (CME) with an…
Our planet is under the influence of a positive polarity CH HSS which is causing geomagnetic storms reaching G1 – Minor levels. During the past 24 hours, solar wind parameters reflected the onset of a co-rotating interactive region (CIR) followed by the influence of…
