A long-duration M3.3 flare erupted from just beyond the east-southeast limb at 11:00 UTC on January 11, 2026, as CME and coronal hole influences continued to disturb the solar wind environment. The geomagnetic field reached G1 - Minor to G2 - Moderate storm levels on January 10–11 under combined CME and coronal hole high-speed stream effects. Elevated solar wind parameters and unsettled-to-active geomagnetic conditions are expected to persist through January 14.

Multiple coronal mass ejections (CMEs) launched from Active Region 4334 on January 8, 2026, are expected to deliver a glancing blow to Earth between late January 10 and early January 11, according to the U.S. Space Weather Prediction Center (SWPC). The interaction of several CMEs and a coronal hole high-speed stream is forecast to cause isolated G1 - Minor geomagnetic storm conditions. Aurora may become visible across high latitudes, including the northern tier of the United States, such as northern Michigan and Maine.

A long-duration solar flare measuring M7.1 at its peak erupted from Active Region 4324 at 13:51 UTC on December 31, 2025. The event started at 13:12 and ended at 14:11 UTC.

A coronal mass ejection (CME) associated with an M4.2 solar flare from Region 4317 is expected to produce a G1 - Minor geomagnetic storm as it grazes Earth late on December 31 into early January 1, 2026.

Auroras are expected across much of the northern United States, southern Canada, and northern Europe on December 9, 2025, following a forecasted geomagnetic disturbance caused by a coronal mass ejection (CME) produced during the December 6 M8.1 solar flare.

A major solar flare measuring X1.1 erupted from Active Region 4298 at 05:01 UTC on December 8, 2025. The event started at 04:49 and ended at 05:04 UTC.

A G3 - Strong geomagnetic storm watch is in effect following a powerful M8.1 solar flare from geoeffective Active Region 4299 at 20:39 UTC on December 6, 2025. The resulting full-halo coronal mass ejection (CME) is expected to impact Earth between early and midday UTC on December 9, possibly producing periods of strong geomagnetic storming.

A strong solar flare measuring M8.1 erupted from Active Region 4299 at 20:39 UTC on December 6, 2025. The event started at 20:29 and ended at 20:49 UTC. A full-halo coronal mass ejection was produced, with impact expected early to midday on December 9, potentially causing periods of G3 - Strong geomagnetic storming.

A strong M6.0 solar flare erupted from Region 4300 at 02:50 UTC on December 4, 2025, producing a non-Earth-directed CME. The flare occurred as Earth’s geomagnetic field remained in storm conditions, including a G3 - Strong interval driven by the arrival of a negative CH HSS and the flank of the CME launched on December 1. Solar wind parameters showed elevated density, strong IMF values, and Bz reaching −15 nT before transitioning to high-speed stream conditions.

NOAA’s Space Weather Prediction Center (SWPC) issued a G2 - Moderate geomagnetic storm watch for December 3 and 4, 2025, following a coronal mass ejection (CME) associated with the X1.9 solar flare from Active Region 4299 on December 1. The CME is expected to deliver a glancing blow to Earth’s magnetic field, coinciding with a co-rotating interaction region (CIR) and a sector boundary crossing, increasing the potential for moderate geomagnetic storming and visible auroras at mid-latitudes.
