A long-duration M1.7 solar flare erupted from geoeffective Active Region 2981 at 03:01 UTC on November 2, 2021. The event started at 01:20 and ended at 03:50 UTC. The event was associated with a 10cm Radio Burst (tenflare) peaking at 110 sfu at 02:36 UTC. A 10cm…
A moderately strong M1.5 solar flare erupted from AR 2887 at 01:45 UTC on November 1, 2021. The event started at 00:57 and ended at 02:10 UTC. It was associated with a Type II Radio Emission at 01:29 UTC with an estimated velocity of 626 km/s. Type II emissions…
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 G1 – Minor geomagnetic storm watch is in effect for September 1 and a G2 – Moderate for September 2, 2021. The geomagnetic field is expected to be at quiet to unsettled conditions on August 31 due to the delayed anticipated passage of the August 26th coronal mass…
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…
