Moderate M1.1 solar flare erupts at 15:37 UTC on November 8, 2026

A moderate M1.1 solar flare erupted at 15:37 UTC on November 8, 2026.

This event began at 15:29 UTC and ended at 15:49 UTC, originating from solar region 4566. Today’s flares include an M1.7 flare peaking at 07:46 UTC from region 4566 and the M1.1 flare peaking at 15:37 UTC from the same region. Numerous C-class flares were also recorded from region 4566 throughout the day.

In 24 hours to 12:30 UTC on November 8, solar activity remained at moderate levels, with multiple M-class and numerous C-class flares observed. There was continued sunspot development in the intermediate and trailing spots of region 4566. No Earth-directed coronal mass ejections were detected during this period.

M-class flares (R1 – Minor to R2 – Moderate) are likely over November 8–10, with a slight chance for an X-class (R3 – Strong) flare.

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 was at moderate levels, and the greater than 10 MeV proton flux remained at background values. The electron flux is likely to be at normal to moderate levels on November 8–9, with high levels likely by November 10. There is a slight chance for the greater than 10 MeV proton flux to reach S1 – Minor radiation storm thresholds over November 8–10.

Solar wind parameters showed ongoing effects from a negative polarity coronal hole high-speed stream, with total field strength up to 15 nT, Bz reaching -11 nT, and solar wind speeds rising from near 500 km/s to about 763 km/s. Conditions are expected to remain enhanced as the coronal hole influence continues through November 10.

The geomagnetic field was unsettled to G1 – Minor storm levels due to the continued negative polarity coronal hole high-speed stream. G1 – Minor geomagnetic storm conditions are expected, with a chance for G2 – Moderate storms on November 8–9. Conditions are forecast to return to unsettled to active levels as coronal hole effects decrease on November 10.
