Major network outages in U.S. following two X-class solar flares
A widespread network outage was reported in the United States on Thursday morning, February 22, 2024, following two major eruptions on the Sun, an X1.8 flare at 23:07 UTC on February 21 and X1.7 at 06:32 UTC on February 22. Both erupted from Active Region 3590.
Two X-class solar flares – X1.8 and X1.7 erupt from Region 3590
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.
Major X2.5 solar flare erupts from AR 3576, producing large CME
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.
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.
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.
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.
Multiple M-class solar flares and CMEs, possible CME impact on December 27
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.
