Minor C8.9 solar flare erupts at 03:24 UTC on November 8, 2026

A minor C8.9 solar flare erupted at 03:24 UTC on November 8, 2026.

Today’s flares include a C3.9 flare peaking at 00:49 UTC from region 4566, a C4.4 flare peaking at 01:07 UTC from region 4566, and a C2.3 flare peaking at 01:39 UTC from region 4566.

In 24 hours to 00:30 UTC on November 8, solar activity increased to moderate levels with region 4566 being the main source of X-ray activity. Three R1 – Minor radio blackout events were observed, with the largest being an M1.9 flare at 18:42 UTC on November 7.

Solar activity is likely to reach moderate levels with the potential for M-class flares (R1-R2: Minor-Moderate) and a chance for an X-class flare (R3: Strong) from November 8 to 10.

Active sunspot regions presently observed on the Earth-facing solar disk include AR 4565 (N13W31 – Alpha), AR 4566 (S06E06 – Beta-Gamma-Delta), AR 4567 (N18W83 – Alpha), AR 4568 (S09E25 – Alpha), AR 4569 (S06W07 – Alpha), and AR 4570 (S13E47 – Alpha).

Over the past 24 hours the greater than 2 MeV electron flux decreased to moderate levels, and the greater than 10 MeV proton flux was at background values. The greater than 2 MeV electron flux is likely to remain at normal to moderate levels on November 8 and 9, with high levels likely by November 10. There is a slight chance for the greater than 10 MeV proton flux to exceed S1 – Minor levels through November 10.

Solar wind parameters reflected continued influence from a negative polarity coronal hole high speed stream. The magnetic field reached 15 nT, and the Bz component was as far south as -11 nT. Solar wind speeds increased from around 425 km/s to a peak near 736 km/s. The solar wind environment is expected to remain enhanced as coronal hole high speed stream influence persists from November 8 to 10.

The geomagnetic field reached G1 – Minor geomagnetic storm levels late in the UT day. G1 – Minor conditions are expected to continue, with a chance for G2 – Moderate storm levels on November 8 and likely continuing into November 9 due to ongoing coronal hole high speed stream influence. Unsettled to active conditions are likely as the coronal hole effects diminish by November 10.
