Impulsive X1.5 solar flare erupts from geoeffective AR 3006
An impulsive solar flare measuring X1.5 erupted at 13:55 UTC on May 10, 2022, from Active Region 3006. The event started at 13:50 UTC and ended at 13:59.
X1.1 solar flare erupts from the Sun’s SE limb
A major solar flare measuring X1.1 erupted from a region located at the Sun’s southeastern limb at 13:25 UTC on May 3, 2022. The event started at 13:09 UTC and ended at 13:31.
Major X1.1 solar flare erupts from the Sun’s west limb
A major solar flare measuring X1.1 erupted from the Sun’s west limb at 13:47 UTC on April 30, 2022. The event started at 13:37 UTC and ended at 13:52.
Major X2.2 solar flare erupts just beyond the southwest limb of the Sun
A major solar flare measuring X2.2 at its peak erupted at 03:57 UTC on April 20, 2022 from a region located just beyond the southwest limb of the Sun – likely former Region 2992. The event started at 03:41 UTC and ended at 04:04.
Major X1.1 solar flare erupts from Active Region 2994
A major solar flare measuring X1.1 at its peak erupted from newly numbered Active Region 2994 at 03:34 UTC on April 17, 2022. The event started at 03:17 UTC and ended at 03:51. A coronal mass ejection (CME) was produced during the event but the location of the source region does not favor Earth-directed CMEs. This will change in the days ahead as the region turns into geoeffective position.
Major X1.3 solar flare erupts from Active Region 2975
A major solar flare measuring X1.3 erupted from Active Region 2975 at 17:37 UTC on March 30, 2022. The event started at 17:21 UTC and ended at 17:46. The region is located in an area that favors Earth-directed coronal mass ejections (CMEs). A Type II Radio Emission…
Major, long-duration X1.0 solar flare erupts from AR 2887, Earth-directed CME produced
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…
Major X1.5 solar flare erupts — the first X-class flare of Solar Cycle 25
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….
Powerful double solar eruption beyond the east limb
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…
Glancing blow expected from CME produced by major X8.2 solar flare
A major X8.2 solar flare that erupted at 16:06 UTC on September 10, 2017 from Region 2673, produced a powerful asymmetric full halo Coronal Mass Ejection (CME) and it appears one part of it is heading toward Earth. A glancing blow is expected late on September 13….
