A G2 – Moderate geomagnetic storm watch is in effect for April 16, 2025, due to an Earth-directed coronal mass ejection from an April 13 filament eruption. Solar activity is forecast to remain moderate through April 15, with potential X-class flares from Region 4055, before decreasing to low levels on April 16.
A major solar flare measuring X1.1 erupted from a region located near the Sun’s east limb at 15:20 UTC on March 28, 2025. The event started at 14:57 and ended at 15:43 UTC.
A coronal mass ejection (CME) launched from the Sun on March 21, 2025, is expected to impact Earth early on March 23, prompting a G3 – Strong geomagnetic storm watch issued by NOAA’s Space Weather Prediction Center (SWPC). The CME was associated with an M1.2 solar flare from Region 4028 at 15:34 UTC.
A long-duration M3.9 solar flare erupted from a region off the NW limb at 23:02 UTC on February 24, 2025, producing a large coronal mass ejection (CME) and triggering a minor solar radiation storm. While this CME is not Earth-directed, solar wind conditions have become enhanced yesterday, and geomagnetic activity may increase in the coming days. There is a 65% chance of an M-class flare through February 27 and a 25% chance of an X-class flare.
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 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.
