Filament eruption produces Earth-directed CMEs
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).

A moderately strong solar flare registered as M3.5 erupted from the southeast limb of the Sun at 16:35 UTC on March 16, 2024. The event started at 16:22 and ended at 16:44 UTC. This flare was partially eclipsed by the edge of the Sun, which means it was much stronger than M3.5.
Although solar activity was at low levels over the past 24 hours, multiple long-duration C-class solar flares, associated with activity from Region 3599 as it rotated beyond the west limb, produced coronal mass ejections (CMEs) that sent proton flux rising to S1 – Minor levels.
A strong solar flare measuring M7.4 erupted from Active Region 3599 (beta-gamma-gamma) at 12:13 UTC on March 10, 2024. The event started at 12:00 UTC and ended at 12:20.
A solar filament eruption centered near S35E50 took place around 20:00 UTC on March 5, 2024, producing a large coronal mass ejection (CME) which is expected to slightly graze Earth late March 8. G1 – Minor geomagnetic storms are possible on March 9 due to the combined effects of a negative polarity CH HSS and this CME.
A major X6.3 solar flare erupted from Active Region 3590 at 22:34 UTC on February 22, 2024. The event started at 22:08 UTC and ended at 22:43.
Two X-class solar flares erupted over the past 9 hours — the first was X1.8 at 23:07 UTC on February 21 and the second X1.7 at 06:32 UTC on February 22, 2024. Both erupted from Active Region 3590.
An impulsive solar flare measuring X2.5 erupted from Active Region 3576 (beta-gamma) at 06:53 UTC on February 16, 2024. The event started at 06:42 and ended at 06:58 UTC. This is the fourth strongest solar flare of Solar Cycle 25 — after X5.0 on December 31, 2023, X3.3 on February 9, 2024, and X2.8 on December 14, 2023.
At least three coronal mass ejections (CMEs) are heading toward Earth. The impact is expected early on February 13 (UTC), producing G2 – Moderate or stronger geomagnetic storming.
Proton flux started rapidly rising at 07:30 UTC on February 12, 2024, following what appears to be an eruption from the old Region 3575 – now traversing the farside of the Sun.
