Moderate M2.6 solar flare erupts at 14:54 UTC on July 1, 2026

A moderate M2.6 solar flare erupted at 14:54 UTC on July 1, 2026.

Today’s flares include an M2.5 flare peaking at 08:17 UTC from region 4479, an M1.5 flare at 07:35 UTC (region 4479), an M1.3 flare at 10:08 UTC (region 4479), an M1.1 flare at 06:27 UTC (region 4479), and another M1.1 flare at 14:31 UTC. No M2.6 flare at 14:54 UTC is specifically listed in the confirmed event summaries, but several moderate M-class events are present today mainly from region 4479. X-class activity is not reported for July 1, 2026.

In 24 hours to 12:30 UTC on July 1, solar activity reached high levels due to recent major activity, including an X1.1 flare at 20:50 UTC on June 30. Multiple M-class flares and growth in three main active regions were observed. Preliminary CME analysis suggested a potential Earth impact from July 3 to 4.

Solar activity is likely to reach moderate levels (R1 – Minor to R2 – Moderate), with a slight chance for X-class flares (R3 – Strong) due to the activity potential of regions 4475, 4478, and 4479.

Active sunspot regions presently observed on the Earth-facing solar disk include AR 4475 (S09W63 – Beta), AR 4477 (S14W31 – Beta), AR 4478 (S05W06 – Beta-Gamma-Delta), AR 4479 (N16W24 – Beta-Gamma-Delta), and AR 4480 (S18W30 – Beta).

Over the past 24 hours, the greater than 2 MeV electron flux was at moderate to high levels, peaking at 5 687 pfu. Greater than 10 MeV proton levels remained at background. The greater than 2 MeV electron flux is expected to again reach high levels on July 1 and July 3, with moderate levels likely on July 2 due to possible CME arrival. There is a slight chance for an S1 – Minor solar radiation storm event due to current flare activity.

Solar wind parameters were enhanced due to a previous CME arrival. Total magnetic field strength increased to 18 nT, with variable Bz and several southward intervals to -10 nT. Solar wind speeds remained steady near 425 km/s. Solar wind conditions are expected to stay enhanced as CME activity persists, with further enhancements possible later on July 1 or early on July 2, and an additional increase possible on July 3 with another CME arrival.

The geomagnetic field was quiet initially, followed by active to G1 – Minor storm conditions in the latter half of the summary period due to CME effects. Minor (G1) storming is expected, with a chance for isolated periods reaching moderate (G2) levels through early July 1. Unsettled to active conditions may occur on July 2 with potential CME passage. G1 to G2 conditions are possible by July 3 depending on further CME analysis.
