A long-duration solar flare measuring M2.7 at its peak erupted at 20:02 UTC on August 30, 2025. The eruption produced an asymmetric full halo coronal mass ejection (CME), with impact expected late September 1 into September 2. A G3 – Strong geomagnetic storm watch is in effect.
A full-halo coronal mass ejection (CME) first visible in LASCO C2 imagery at 03:36 UTC on March 13, 2023, produced S1 – Minor Solar Radiation Storm at 07:50 UTC.
A long-duration C2 solar flare erupted from an area west of AR 2962 on March 10/11, 2022, producing full halo coronal mass ejection (CME). As a result, a G2 – Moderate geomagnetic storm watch is in effect. The event started around 18:00 UTC on March 10 and ended…
A long-duration solar flare measuring C7.4 at its peak erupted from Active Region 2790 — positioned in Earth-striking zone — at 16:32 UTC on December 7, 2020. The event started at 15:46, peaked at 16:32, and ended at 17:33 UTC. An asymmetric full halo coronal mass…
An asymmetric full halo CME with a likely Earth-directed component erupted May 6, 2019. The source is still unknown, it is possible this was another stealth CME. Sun's northeastern limb continued exhibiting increased CME activity on May 6 and 7, 2019. This…
Filament eruption in the SSE quadrant of the Sun produced a partial-halo Coronal Mass Ejection (CME) first observed in coronagraph imagery near 08:45 UTC on June 19 (above). WSA-Enlil model suggests a glancing blow early on June 23. Beta-Gamma-Delta classified…
A huge solar filament is facing Earth today and, if it doesn't erupt, will continue to do so in the coming days. Stretched out, it would be more than 857 780 km or 533 000 miles long, which is more than 67 Earth diameters. Image below shows this filament as…
A moderately strong, long duration solar flare measuring M2.4 at its peak time erupted from Region 2282 ('beta') late on February 9, 2015. The event started at 22:19, peaked at 23:35 and ended at 00:16 on February 10.This flare had associated Type II (estimated
An icy comet with estimated size of few tens of meters plunged into the Sun on August 19/20, 2013 but just before it dissipated, a far-side region on the Sun expelled a magnificent full-halo CME.
Today's comet belonged to Kreutz Sungrazer family which
Region 1678 erupted with massive, full-halo, Coronal Mass Ejection around 04:00 UTC on March 5, 2013. The CME will have no effect on Earth as Region 1678 is on farside of the Sun. This old and active region is about to rotate onto the eastern limb by this
