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.
A moderately strong M6.5 solar flare erupted from Active Region 3576 at 03:48 UTC on February 12, 2024. The event started at 03:23 and ended at 03:53 UTC.
A strong solar flare measuring M9.0 erupted at 23:07 UTC on February 10, 2024 from geoeffective Active Region 3576. The event started at 22:56 and ended at 23:14 UTC.
A powerful solar flare measuring X3.3 erupted behind the SW limb of the Sun (AR 3575) at 13:14 UTC on February 9, 2024. This solar flare is the second most intense in Solar Cycle 25, following an X5.0 flare that occurred on January 31, 2023.
A long-duration M5.1 solar flare erupted from Active Region 3575 at 03:31 UTC on February 7, 2024. The event started at 03:04 and ended at 04:11 UTC. The flare follows M4.2 from the same region at 03:12 UTC on February 6.
A long-duration M4.2 solar flare erupted from Active Region 3575 at 03:12 UTC on February 6, 2024. The event started at 02:37 UTC and ended at 03:37.
Following the M6.7 solar flare from Active Region 3559 on January 29, 2024, enhanced proton levels were recorded, with the greater than 10 MeV reaching the S2 – Moderate threshold and greater than 100 MeV peaking at 0.67 pfu.
A moderately strong solar flare measuring M6.7 erupted from Active Region 3559 (beta-gamma) at 04:38 UTC on January 29, 2024. The event started at 03:54 and ended at 05:15 UTC.
