Moderate M1.4 solar flare erupts at 17:17 UTC on November 7, 2026

A moderate M1.4 solar flare erupted at 17:17 UTC on November 7, 2026.

Today’s flares include an M1.2 event at 12:43 UTC from region 4566, as well as numerous C-class flares: C6.2 at 11:57 UTC (region 4566), C5.9 at 00:53 UTC (region 4566), C5.5 at 07:35 UTC (region 4566), and several others throughout the day from region 4566. No X-class solar flares were observed.

In 24 hours to 12:30 UTC on November 7, solar activity was at low levels, with numerous C-class flares and the largest being a C6.2 at 11:57 UTC. Minor growth was observed in region 4566. No Earth-directed coronal mass ejections were detected in available imagery.

Solar activity is expected to remain low, with a chance for M-class flares (R1-R2 – Minor-Moderate), and a slight chance for an X-class flare (R3 – Strong), from November 7 to 9.

Active sunspot regions presently observed on the Earth-facing solar disk include AR 4565 (N13W18 – Beta), AR 4566 (S06E19 – Beta-Gamma-Delta), AR 4567 (N18W70 – Beta), AR 4568 (S08E40 – Alpha), AR 4569 (S06E07 – Alpha), and AR 4570 (S13E59 – Alpha).

Over the past 24 hours, the greater than 2 MeV electron flux reached high levels with a peak of 4 631 pfu at 17:20 UTC on November 6. The greater than 10 MeV proton flux remained at background levels. The greater than 2 MeV electron flux is likely to remain at normal to moderate levels through November 9, with the greater than 10 MeV proton flux expected to remain at background.

Solar wind parameters over the past 24 hours reflected persistent influence from a negative polarity coronal hole high speed stream. The total magnetic field reached 15 nT, and the Bz component dipped as low as -11 nT. Solar wind speeds increased from around 350 km/s to a peak of 510 km/s. The solar wind environment is expected to remain enhanced as this influence continues through November 9.

The geomagnetic field was at quiet to unsettled levels during the past 24 hours. Conditions are likely to reach G1 – Minor geomagnetic storm levels, with a chance for G2 – Moderate storm levels, from November 7 to 9 due to ongoing high speed solar wind streams.
