Highlights of Solar and Geomagnetic Activity 30 June - 06 July 2025

Solar activity was at low levels through the period. The largest events were a pair of C2.5 flares from Regions 4126 (N07, L=264, class/area Dro/030 on 01 Jul) and 4130 (S11, L=140, class/area Dai/040 on 06 Jul) at 02/1835 UTC and 04/0747 UTC, respectively. No regions exhibited delta configurations, with Region 4129 (N02, L=171, class/area Dso/060 on 04 Jul) being the only one to carry a beta-gamma characteristic. The remaining regions were simple alpha or beta spots. There were several filament and prominence events that produced CMEs during the period, but analysis deemed none appeared to be Earth-directed.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit reached high levels on 30 Jun-03 Jul, with a peak flux of 8,730 pfu at 30/1625 UTC, and moderate levels on 04-06 Jul.
Geomagnetic field activity was at quiet levels on 02 July, quiet to unsettled levels on 30 Jun-01 Jul, reached active levels on 03-05 Jul, and G1 (Minor) storm levels on 06 Jul, all likely associated with negative polarity CH HSS influence. Total field reached a peak of 14 nT at 03/0900 UTC, Bz saw a maximum southward deflection to -13 nT at 03/1220 UTC, and wind speeds observed a maximum of 579 km/s 01/0402 UTC.
Forecast of Solar and Geomagnetic Activity 07 July - 02 August 2025
Solar activity is expected to be at low levels from 07-11 July, with several regions expected to rotate off the disk and no major groups expected to return. After 12 July, several returning regions could prompt conditions to increase to moderate levels through 25 Jul, then be hit or miss for the remainder of the period as several regions rotate off the disk and others rotate on.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is expected to be high levels from 20-29 Jul under recurrent CH HSS influence. Moderate levels are expected from 07-19 Jul and again from 30 Jul-02 Aug.
Geomagnetic field activity is expected to be at G1-G2 (Minor-Moderate) storm levels early on 07 Jul as possible transient effects co-mingle with lingering CH HSS influence. Quiet to unsettled conditions are then expected to return from 08-21 Jul, with isolated active periods possible on 15-16 Jul, under positive polarity CH HSS influence. From 22-27 Jul, a shift to negative polarity CH HSS inluence is likely to bring unsettled to active conditions, with isolated periods of G1 (Minor) storm conditions on 23 Jul. Mostly quiet levels are then expected from 28-31 Jul before another negative polarity CH moves into a geoeffective position on 01 Aug, bringing in unsettled to active levels through 02 Aug.
