Moderate M1.0 solar flare erupts at 00:26 UTC on November 2, 2025

A moderate M1.0 solar flare erupted at 00:26 UTC on November 2, 2025.

Today’s flares include no reported events according to the 2025 Nov 02 edited event summaries.

In 24 hours to 00:30 UTC on November 2, solar activity was low. New flux emergence was observed, with one C4.7 flare reported at 16:55 UTC on November 1. A new region was numbered, while previously numbered regions decayed.

Solar activity is expected to begin increasing over the next few days. There is an increasing chance for M-class flares (R1 – Minor to R2 – Moderate) from November 2 through 4, and a slight chance for X-class flares (R3 – Strong) as older active regions rotate back onto the disk.

Active sunspot regions presently observed on the Earth-facing solar disk include AR 4267 (N02W52 – Beta) and AR 4272 (N22E76 – Alpha).

Over the past 24 hours, the greater than 2 MeV electron flux reached high levels with a maximum of 10 600 pfu, while the greater than 10 MeV proton flux remained near background levels. The greater than 2 MeV electron flux is expected to remain at moderate to high levels, with a slight chance for the greater than 10 MeV proton flux to reach S1 – Minor levels as active regions return.

Solar wind parameters remained enhanced under a positive polarity CH HSS. Solar wind speed decreased from 650 km/s to 500 km/s, with Bt steady at 6–7 nT and Bz between +4 and -6 nT. Phi angle stayed positive. Near-Earth solar wind conditions are expected to return to background levels by November 3–4, with a low-confidence potential for weak CME enhancements on November 2.

The geomagnetic field was at unsettled to active levels due to diminishing CH HSS effects. The geomagnetic field is expected to be at quiet to active levels through November 3, with HSS activity persisting and a possible glancing blow from the October 30 CME.
