Solar activity reached high levels on October 28, 2021, with a pair of M-class flares from geoeffective AR 2887 at 07:40 and 10:28 UTC, followed by a major X1.0 flare at 15:35 UTC which generated an Earth-directed coronal mass ejection (CME). As a result, a G3 -…
A major, long-duration solar flare measuring X1.0 at its peak erupted from geoeffective Active Region 2887 at 15:35 UTC on October 28, 2021. The event started at 15:17 and ended at 15:48 UTC. The event was associated with a Type II Radio Emission with an estimated…
Coronal mass ejection (CME) produced by M1.6 solar flare at 06:40 UTC on October 9, 2021, reached DSCOVR spacecraft at 01:48 UTC and Earth at 02:30 UTC on October 12, 2021. The impact sparked a G2 – Moderate geomagnetic storm. In 24 hours to 00:30 UTC on October 12,…
A partial, asymmetric halo coronal mass ejection (CME) was produced by C1.6 solar flare from Region 2871 at 06:34 UTC on September 28, 2021. Another, relatively weak CME was produced by the same region at 12:00 UTC on September 27, with glancing influence possible….
A moderately strong solar flare measuring M2.8 at its peak erupted from Active Region 2871 at 04:42 UTC on September 23, 2021. The event started at 04:35 and ended at 04:50 UTC. The flare was associated with a Type II Radio Emission at 04:44 UTC with an estimated…
A moderately strong solar flare measuring M4.7 at its peak erupted from geoeffective Active Region 2860 at 06:15 UTC on August 28, 2021. The event started at 05:39 and ended at 06:23 UTC. The flare event follows increased solar activity with numerous c-class flares…
A glancing blow CME from the July 20 eruption could bring a chance for G1 – Minor geomagnetic storm condition on July 23, 2021. As a result, a G1 Geomagnetic Storm Watch is in effect. A ~4-degree solar filament centered at approximately N25E65 erupted from the…
A major solar flare measuring X1.5 at its peak erupted on the Sun's NW limb — most likely from the newly-formed Active Region 2838 — on July 3, 2021, producing R3 – Strong radio blackout. The event started at 14:18, peaked at 14:29, and ended at 14:34 UTC….
A moderately strong solar flare measuring M2.7 at its peak erupted from the newly-formed Active Region 2838 on July 3, 2021. The event started at 07:04 UTC, peaked at 07:17, and ended at 07:22. The position of this region does not favor Earth-directed coronal mass…
A long-duration C9.4 solar flare erupted from Active Region 2824 at 23:13 UTC on May 28, 2021, producing a strong coronal mass ejection (CME) and S1 – Minor proton radiation storm. The flare event was associated with Type II Radio Emission with an estimated velocity…
