A long-duration solar flare measuring M2.0 erupted from AR 2891, currently located on the Sun's northwestern limb. The event started at 15:47, peaked at 17:02 and ended at 17:37 UTC. The location of this region does not favor Earth-directed CMEs. However, a…
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…
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 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…
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…
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 moderately strong solar flare measuring M1.1 at its peak erupted at 23:28 UTC on October 20, 2017 from the vicinity of old Region 2682, numbered 2673 two rotations ago. Radio signatures suggested and coronagraph imagery confirmed, a Coronal Mass Ejection (CME) was…
A powerful double solar flare eruption took place beyond the Sun's east limb early October 18, 2017. The responsible region is now rotating into Earth view and will be visible in a couple of days. The eruption was associated with a Type II (estimated velocity 1…
