Moderate M1.9 solar flare erupts at 18:42 UTC on November 7, 2026

A moderate M1.9 solar flare erupted at 18:42 UTC on November 7, 2026.

The M1.9 flare is not listed among today’s confirmed solar events. Today’s flares include M1.2 at 12:43 UTC from region 4566 and M1.4 at 17:17 UTC from region 4566, along with multiple C-class events.

In 24 hours to 12:30 UTC on November 7, solar activity was at low levels. Numerous C-class flares were observed, with the largest being a C6.2 event at 11:57 UTC.

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

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 value of 4 631 pfu. The greater than 10 MeV proton flux remained at background levels. The greater than 2 MeV electron flux is likely to be at normal to moderate levels during November 7–9. The greater than 10 MeV proton flux is expected to remain at background levels through November 9.

Solar wind parameters reflected the influence of a negative polarity coronal hole high speed stream. Total magnetic field strength peaked at 15 nT, and the Bz component reached as far south as -11 nT. Solar wind speed increased from 350 km/s to 510 km/s, with phi primarily negative. The solar wind environment is expected to remain enhanced as coronal hole high speed stream influences continue through November 9.

The geomagnetic field was at quiet to unsettled levels over the past 24 hours. Geomagnetic conditions are likely to reach G1 – Minor storm levels, with a chance for G2 – Moderate storm conditions, from November 7 to 9 due to the continued influence of a negative polarity coronal hole high speed stream.
