Three CMEs heading toward Earth, impact expected on February 13
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 rising after powerful farside eruption, S1 – Minor solar radiation storm
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.
M6.5 solar flare erupts from AR 3576, G2 – Moderate geomagnetic storm watch
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.
Strong M9.0 solar flare erupts from geoeffective Region 3576
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.
Major X3.3 solar flare erupts behind the SW limb, S2 – Moderate solar radiation storm
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.
Long-duration M5.1 solar flare erupts from Region 3575
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.
Long-duration M4.2 solar flare erupts from Region 3575
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.
S2 – Moderate solar radiation storm following M6.7 solar flare
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.
M6.7 solar flare erupts from Region 3559, producing S2 – Moderate solar radiation storm
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.
Solar filament eruption produces Earth-directed CME
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.
