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 strong M5.6 solar flare erupted from Active Region 4046 at 07:55 UTC on April 1, 2025, producing a 10cm radio burst but showing no signs of an associated coronal mass ejection (CME). Meanwhile, a solar radiation storm triggered by the X1.1 flare on March 28 reached the S2 – Moderate threshold at 02:05 UTC today.
Minor solar radiation storm conditions were registered on March 31, 2025, after an X1.1 solar flare erupted from the Sun’s east limb on March 28.
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.
Earth is currently experiencing heightened solar wind conditions and geomagnetic storming due to the passage of a co-rotating interaction region (CIR) ahead of a high-speed stream from a large coronal hole in the southern hemisphere.
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.
