An impulsive solar flare measuring X2.0 erupted from Active Region 4001 at 19:27 UTC on February 23, 2025. The event started at 19:22 and ended at 19:34 UTC. A coronal mass ejection (CME) was produced but the location of this region does not favor Earth-directed CMEs.
A moderately strong solar flare measuring M7.6 erupted from Active Region 3981 at 11:04 UTC on February 6, 2025. The event started at 10:47 and ended at 11:16 UTC.
A moderately strong solar flare measuring M8.8 erupted from Active Region 3981 at 03:58 UTC on February 3, 2025. The event started at 03:52 and ended at 04:04 UTC.
An impulsive solar flare registered as M5.1 erupted from Active Region 3977 at 14:04 UTC on February 2, 2025. The event started at 13:58 and ended at 14:08 UTC. With the region positioned at the center of the solar disk, the likelihood of Earth-directed activity remains elevated in the coming days. Meanwhile, the solar wind continues to be influenced by a positive polarity coronal hole high-speed stream, potentially leading to geomagnetic disturbances.
A strong solar flare measuring M6.7 erupted from Active Region 3978 at 14:06 UTC on January 31, 2025, producing a coronal mass ejection (CME). The event started at 13:40 and ended at 14:25 UTC. This is the strongest solar flare since M7.4 on January 17.
A G1 – Minor geomagnetic storm watch is in effect for January 31 and February 1, 2025, due to a coronal hole high-speed stream (CH HSS) influence coupled with the potential arrival of a CME.
A coronal mass ejection (CME) produced by the M3.3 solar flare at 10:39 UTC on January 21, 2025, is expected to deliver a glancing blow from late January 24 into January 25. This was a long-duration flare that started at 10:08 UTC and ended at 11:00.
A major solar flare measuring X1.8 erupted from Active Region (AR) 3947 at 12:48 UTC on January 4, 2025. The event started at 12:35 and ended at 12:56 UTC. This is the third X-class solar flare after X1.2 at 11:39 UTC and X1.1 at 22:41 UTC on January 3 — all produced by AR 3947.
A major solar flare measuring X1.1 erupted from Active Region (AR) 3947 at 22:41 UTC on January 3, 2025. The event started at 22:32 and ended at 22:51 UTC. This is the second X-class solar flare produced on January 3 — both from AR 3947. Meanwhile, CME produced on January 1 impacted Earth early January 4, sparking G1 – Minor geomagnetic storm.
A major solar flare measuring X1.2 erupted from Active Region (AR) 3947 at 11:39 UTC on January 3, 2025. This is the first X-class solar flare of 2025. The event started at 11:29 and ended at 11:49 UTC.
