Highlights of Solar and Geomagnetic Activity
14 - 20 July 2025

Solar activity was at low levels. The largest flare was a C7.6 from
Region 4136 (N20, L=17, class/area=Cao/210 on 20 Jul) at 20/0741
UTC. C-class activity was also observed from several other regiond
during the highlight period. No Earth-directed CME activity was
observed.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at
high levels on 14-20 Jul in response to persistent positive polarity
CH HSS influence.

Geomagnetic field activity reached G1 (Minor) storm levels on 14,
15, and 17 Jul due to positive polarity CH HSS influence. Solar wind
speeds were elevated to as high as 700 km/s on 15 and 17 Jul. The
remaining days were at quiet to active levels despite enhanced solar
wind parameters.
