Minor C8.2 solar flare erupts at 12:46 UTC on November 2, 2025

A minor C8.2 solar flare erupted at 12:46 UTC on November 2, 2025.

Today’s flares include a moderate M1.0 flare at 00:26 UTC, several C-class events throughout the day, and no reported X-class flares.

In 24 hours to 12:30 UTC on November 2, solar activity reached moderate levels due to an M1.0 flare, with new flux emergence observed around one active region and decaying of others to plage.

Solar activity is expected to gradually increase over the next few days, with low activity initially but an increasing chance for moderate M-class flares and a slight chance for strong X-class flares as returning regions rotate onto the visible solar 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 was at high levels, peaking at 10 600 pfu, while the greater than 10 MeV proton flux remained near background levels. The electron flux is expected to stay at moderate to high levels as the high speed stream influence wanes, with a slight chance for the proton flux to reach S1 – Minor levels with the returning active regions.

Solar wind conditions were enhanced by a positive polarity coronal hole high speed stream, with speeds decreasing from 650 km/s to 500 km/s, and fairly steady interplanetary magnetic field values. Solar wind parameters near Earth are anticipated to reflect a waning high speed stream influence, returning to background levels by November 3–4. Weak enhancements from a peripheral CME are possible but confidence remains low.

The geomagnetic field was at unsettled to active levels over the last 24 hours, due to slowly diminishing coronal hole high speed stream effects. The geomagnetic field is expected to be at quiet to active levels through November 3, with high speed stream activity persisting alongside a possible glancing blow from the October 30 CME.
