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…
Solar activity has increased from low to moderate levels on Saturday and Sunday, May 22 and 23, 2021, with a series of C- and M-class solar flares produced by Active Region 2824. Multiple CMEs were produced during this period, with several having Earth-directed…
A moderately strong solar flare measuring M1.1 at its peak erupted from Active Region 2824 (Alpha) at 17:11 UTC on May 22, 2021. The event started at 17:03 and ended at 17:16 UTC. Its location does not favor Earth-directed CMEs, but there is a possibility that a…
Two coronal mass ejections (CMEs) with Earth-directed components were produced on the Sun on May 9, 2021. The impact is expected early Wednesday, May 12. Active Region 2833 produced a long-duration C-class solar flare measuring C4.0 at its peak at 14:49 UTC on May 9…
A strong solar flare measuring M3.9 at its peak erupted from Active Region 2822 at 19:04 UTC on May 7, 2021. While this is one of the strongest solar flares of the new solar cycle — SC25, the location of region 2822 does not favor Earth-directed CMEs. This event…
A C3.8 solar flare erupted from Active Region 2816 at 04:35 UTC on April 22, 2021, producing a coronal mass ejection (CME). The event started at 04:10 and ended at 05:00 UTC. The location of the source region favors Earth-directed CMEs. The flare was associated with…
A moderately strong solar flare measuring M1.1 at its peak erupted at 23:42 UTC on April 19, 2021. The event started at 23:19 and ended at 23:59 UTC. The source was Active Region 2816 (beta). Associated with this event were Type II (shock velocity of 750 km/s) and…
