Two CMEs strike Earth, producing G3 – Strong geomagnetic storm
Two coronal mass ejections (CMEs) impacted Earth on September 18, 2023, producing G3 – Strong geomagnetic storming.
Long-duration X1.6 solar flare erupts from Region 3386; S1 – Minor radiation storm
A major, long-duration solar flare measuring X1.6 erupted from Active Region 3386 (beta-delta) at 22:21 UTC on August 5, 2023. The event started at 21:45 and ended at 22:44 UTC.
Double-peaked, long-duration M5.7 solar flare from AR 3363 produced asymmetric halo CME, S2 – Moderate solar radiation storm
A double-peaked, long-duration solar flare measuring M5.7 erupted from Active Region 3363 (beta-delta) at 00:06 UTC on July 18, 2023, producing an asymmetric halo CME and S2 – Moderate solar radiation storm.
Slow-moving Earth-bound CME estimated to arrive July 9 – 10
Active Region 3360 (beta) produced a C8.9 solar flare on July 3, 2023, producing an Earth-directed coronal mass ejection (CME) which is expected to hit Earth on July 9 or 10. The event started at 21:02 UTC, peaked at 21:12, and ended at 21:22.
CIR/CH HSS impact produces G2 – Moderate geomagnetic storming
Co-rotating interaction region (CIR) followed by negative polarity coronal hole high speed stream (CH HSS) produced G1 – Minor and G2 – Moderate geomagnetic storming on Earth on June 15 and 16, 2023.
Mysterious “aurora blobs” confirmed as proton auroras
On April 23, 2023, an unusual spectacle of “Aurora Blobs” baffled observers across Europe. These peculiar auroras, unlike anything seen before, have now been identified as “Proton Auroras,” originating from Earth’s ring current system, according to space physicist Toshi Nishimura of Boston University.
Moderately strong M7.1 solar flare erupts from AR 3288
A moderately strong solar flare measuring M7.1 erupted at 13:09 UTC on May 1, 2023. The event started at 13:02 and ended at 13:09 UTC.
Solar storm briefing and highly informative Q&A by Dr. Tamitha Skov
This highly informative solar storm briefing and Q&A session was made by Dr. Tamitha Skov also known as Space Weather Woman. One of the most interesting parts of the video is when she discusses red aurora, Earth’s weakening magnetic field, the South Atlantic Anomaly, and the upcoming Earth’s magnetic pole flip.
A week of intense solar activity: 2 X- and 25 M-class flares, with 2 Earth-directed CMEs
The period of January 9 to 15, 2023, was marked by intense solar activity, with numerous M and X-class flares being observed. The largest event of the period was an X1.9 flare on January 9, followed by an X1.0 on January 10. There were a total of 2 X-flares and 25 M-flares during the period but only two Earth-directed CMEs were observed from this flurry of activity.
Increased solar activity – glancing blow possible on January 19
Solar activity reached high levels in the past 24 hours, with the strongest event being an M6.0 flare from Region 3191. This event was accompanied by a Type II radio sweep and a Coronal Mass Ejection (CME) signature, however, analysis and modeling indicate that no Earth-directed component was produced. A CME was also observed off the southwest limb at 22:00 UTC on January 14, with analysis and modeling suggesting the possibility of a glancing blow on January 19.
