A major solar flare measuring X7.1 erupted from Active Region 3842 at 22:20 UTC on October 1, 2024, producing a CME that most likely has an Earth-directed component. This is the second-strongest solar flare of Solar Cycle 25.
A long-duration solar flare measuring M7.6 erupted from Active Region 3842 at 23:59 UTC on September 30, 2024. A coronal mass ejection (CME) was not produced during this event but Earth-directed CMEs are possible from this region in the days ahead as it continues evolving and moving into a more geoeffective position.
A major solar flare measuring X4.5 erupted from Active Region 3825 at 15:29 UTC on September 14, 2024. The event started at 15:13 and ended at 15:47 UTC. This is the fifth strongest solar flare of Solar Cycle 25.
A major solar flare measuring X1.3 erupted from an unnumbered active region on the Sun’s SE limb at 09:43 UTC on Thursday, September 12, 2024. The event started at 09:31 and ended at 09:51 UTC.
A long-duration solar flare measuring M5.5 erupted from an emerging region on the southeast limb of the Sun at 13:22 UTC on September 1, 2024. The region was numbered 3813 on September 2.
The coronal mass ejection (CME) produced by the X1.3 solar flare on August 14, 2024, impacted Earth around 14:30 UTC on August 18, producing G3 – Strong geomagnetic storming.
A major, long-duration solar flare measuring X1.1 erupted from a large, geoeffective Active Region 3784 at 06:40 UTC on August 14, 2024. The event started at 06:00 and ended at 07:08 UTC.
A major, long-duration solar flare measuring X1.3 erupted from Active Region 3777 at 19:35 UTC on August 8, 2024. The event started at 19:01 and ended at 19:57 UTC.
A coronal mass ejection (CME) produced by a long-duration M8.2 solar flare at 07:09 UTC on August 1, 2024, reached Earth early on August 4, causing G3 – Strong geomagnetic storming.
An impulsive solar flare measuring X1.5 erupted from geoeffective Active Region 3766 at 02:37 UTC on July 29, 2024. The event started at 02:33 and ended at 02:43 UTC. As a result of recent solar activity, a G3 – Strong geomagnetic storm watch is in effect.
