M2.4 solar flare erupts on July 8, 2025

A moderate M2.4 solar flare erupted at 04:17 UTC on July 8, 2025.

Today’s flares include a C1.9 event that began at 00:10 UTC, peaked at 00:18 UTC, and ended at 00:25 UTC, as well as another C1.9 flare, which began at 01:48 UTC, peaked at 01:56 UTC, and ended at 02:01 UTC.

In 24 hours to 00:30 UTC on July 8, solar activity was low, with only C-class flare activity observed. Most of the flare activity originated from one active region, with additional flux emergence noted. One filament lift-off was observed, with an associated CME not expected to be Earth-directed.

Solar flare activity is expected to remain at low levels from July 8 to July 10.

There are currently 8 numbered active regions on the Earth-side of the Sun: AR 3130 (S10W25 – unclassified), AR 4122 (N12W0 – Alpha), AR 4125 (N22W59 – Alpha), AR 4127 (S20W72 – Beta), AR 4128 (S05W71 – Beta), AR 4129 (N02W57 – Beta), AR 4130 (S10W24 – Beta), AR 4134 (S23W28 – Beta), and AR 4135 (S09E69 – Beta).

Over the past 24 hours, greater than 2 MeV electron flux was at normal to moderate levels, and greater than 10 MeV proton flux was at background levels. These conditions are expected to continue through July 10, barring significant new solar flares.

Solar wind parameters reflected continued but waning influences from a negative polarity coronal hole high speed stream. The total magnetic field declined from 14 nT to about 6 nT, with solar wind speeds around 550 km/s. Mildly elevated solar wind conditions are expected to persist through July 8, returning to nominal by July 9–10.

The geomagnetic field reached G1 – Minor storm levels during the 00–03 UTC period due to negative polarity coronal hole influence. Geomagnetic activity is expected to persist at unsettled to active levels as this influence decreases on July 8, returning to mostly quiet conditions by July 9–10 as nominal solar wind returns.
