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.

Today’s flares include one M1.7 solar flare, peaking at 07:46 UTC from region 4566, and multiple C-class solar flares throughout the day. No X-class flares were recorded in the available event listings for November 8, 2026.

In 24 hours to 12:30 UTC on November 8, solar activity continued at moderate levels, with four M-class flares (the largest being M1.9 on November 7), as well as numerous C-class events. No Earth-directed coronal mass ejections were observed.

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

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 was at moderate levels and the greater than 10 MeV proton flux was at background levels. 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 storm levels over November 8–10.

Solar wind parameters reflected continued influence from a negative polarity coronal hole high speed stream, with total magnetic field reaching 15 nT and solar wind speed peaking at approximately 763 km/s. The solar wind environment is expected to remain enhanced as coronal hole effects continue over November 8–10.

The geomagnetic field was at unsettled to G1 – Minor storm levels under sustained coronal hole high speed stream influence. Geomagnetic activity is expected to reach G1 – Minor storm levels, with a chance for G2 – Moderate storm levels, on November 8–9; unsettled to active conditions are likely on November 10 as coronal hole effects diminish.
