Highlights of Solar and Geomagnetic Activity 26 June - 02 July 2023
Solar activity was generally at R1 (Minor) levels until 02 Jul when R3 (Strong) levels were reached. Weak M-class activity was observed from Regions 3340 (N20, L=234, class/area Eki/350 on 26 Jun) on 26-28 Jun, Region 3354 (N15, L=168, class/area Fkc/1150 on 02 Jul) on 29 Jun and Region 3359 (S22, L=068, class/area Dai/060 on 02 Jul) on 01-02 Jul. Region 3354 produced an X1 flare at 02/2314 UTC. No Earth-directed CMEs were observed during the period.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at high levels on 27 Jun through 02 Jul with a maximum flux of 3,510 pfu observed at 28/1555 UTC.
Geomagnetic field activity was at mostly quiet to isolated unsettled levels throughout the period. A brief interval of active levels was observed the latter half of 29 Jun due to a solar sector crossing
from a negative to a positive sector.
Forecast of Solar and Geomagnetic Activity 03 July - 29 July 2023
Solar activity is expected to be at low to R1-R2 (Minor-Moderate) levels throughout the forecast period.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach high levels on 03-06 Jul and 14-29 Jul due to CH HSS influence.
Geomagnetic field activity is expected to reach unsettled levels on 04-05 Jul, unsettled to active levels on 09-10 Jul with G1-G2 (Minor-Moderate) levels likely on 12-13 Jul due to recurrent CH HSS
activity. Quiet to unsettled levels are expected on 14-29 Jul.
