Moderately strong M7.2 solar flare erupts from Region 3293
A moderately strong M7.2 solar flare erupted from Active Region 3293 at 10:45 UTC on May 3, 2023. The event started at 10:36 and ended at 10:49 UTC.
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.
CME impacts Earth sparking G4 – Severe geomagnetic storm, worldwide aurora
A full-halo coronal mass ejection (CME) produced by an Earth-facing filament eruption on April 21, 2023, impacted Earth at 17:37 UTC on April 23. The impact sparked G4 – Severe geomagnetic storm and produced vivid aurora worldwide.
Earth-facing filament eruption produces M1.7 solar flare and strong CME
An Earth-facing filament near Active Region 3283 erupted at 18:12 UTC on April 21, 2023, producing an M1.7 solar flare and a strong coronal mass ejection (CME).
Moderately strong M5.4 solar flare erupts from Region 3256
A moderately strong solar flare measuring M5.4 erupted from Active Region 3256 at 07:37 UTC on March 30, 2023. The event started at 07:24 and ended at 07:43 UTC.
Impulsive X1.2 solar flare erupts from AR 3256
An impulsive solar flare measuring X1.2 at its peak erupted from AR 3256 at 02:33 UTC on March 29, 2023. The event started at 02:18 and ended at 02:40 UTC.
Red auroras descend to Florida, marking first sighting since 2003 and 1989
A G4 – Severe geomagnetic storm on March 24, 2023, caused red auroras to appear over Florida and other low-latitude areas, marking the first such sighting over Florida in nearly 20 years. Numerous unusual phenomena were observed during this geomagnetic storm, including “aurora dunes” over Alberta, Canada.
Unexpected G4 – Severe geomagnetic storm
A combination of factors led to unexpectedly strong geomagnetic storm levels on Thursday, March 23, and Friday, March 24, 2023. The storm reached G3 – Strong levels at 14:49 UTC on March 23 and escalated to G4 – Severe at 04:04 UTC on March 24. The precise cause of this geomagnetic storm is still under investigation, but it is possible that coronal mass ejections (CMEs) from March 20 to 21 played a role.
G2 – Moderate geomagnetic storming due to CH HSS effects combined with CME
Our planet is under the influence of a positive polarity coronal hole high speed stream (CH HSS) today, March 15, 2023, combined with an impact from the coronal mass ejection (CME) produced on March 10. G2 – Moderate geomagnetic storm threshold was reached at 05:59 UTC and the geomagnetic field is likely to reach G1 – Minor geomagnetic storming levels, with a chance for isolated G2 – Moderate periods on March 15 and 16 due to any flanking effects from CMEs produced on March 11 to 13.
