A G1 – Minor geomagnetic storm watch is in effect for April 14 and 15, 2024 due to two incoming coronal mass ejections (CMEs) — launched on April 11 and 12, combined with coronal hole high speed stream (CH HSS) influences.
A filament channel eruption, approximately 35 degrees in length, began at around 01:00 UTC on March 17, 2024, producing two coronal mass ejections (CMEs).
An approximately 25 degrees in length filament eruption centered near S35W09, began erupting after 09:00 UTC on January 22, 2024, producing an Earth-directed CME. The estimated time of arrival is January 25.
A coronal mass ejection produced by a filament eruption on January 20, 2024, is expected to reach Earth late January 22, producing G2 – Moderate geomagnetic storming.
Multiple M-class solar flares and CMEs were recorded on December 24, 2023. Forecasts indicate potential geomagnetic disturbances with a grazing blow expected late on December 27, 2023.
An impulsive solar flare measuring M5.4 erupted from Active Region 3511 at 23:07 UTC on December 8, 2023. The event started at 22:57 UTC and ended at 23:14.
A large filament eruption centered near N30W30 was observed in H-alpha imagery around 05:00 UTC on November 3, 2023.
An active filament channel in the vicinity of Region 3386 erupted simultaneously with M1.3 solar flare at 08:12 UTC on August 2, 2023, producing an Earth-directed 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).
A long-duration M3.7 solar flare erupted from Active Region 3234 at 20:30 UTC on February 24, 2023, producing a large coronal mass ejection (CME). The event was associated with a filament eruption.
