Highlights of Solar and Geomagnetic Activity 03 - 09 July 2023

Solar activity reached moderate levels (R1-Minor) on 03-07 Jul and declined to low levels on 08-09 Jul. Region 3354 (N16, L=168, class/area Fkc/1150 on 02 Jul) produced an M1.4/Sf at 04/1235 UTC and an M1.0/Sf at 06/1049 UTC. Region 3358 (S13, L=068, class/area Dai/100 on 03 Jul) produced an M1.3/1n at 03/0653 UTC. Region 3361 (N24, L=042, class/area Ekc/260 on 08 Jul) produced an M1.0/Sf on 05/1858 UTC. Region 3359 (S21, L=072, class/area Dao/240 on 06 Jul) produced the largest event of the period, an M4.0/2b at 07/0629 UTC. This event also produced a 190 sfu Tenflare. During the period, no Earth-directed CMEs were detected. 

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at high levels on 03-05 Jul with a peak flux of 3,560 pfu observed at 05/1650 UTC. Normal to moderate levels were observed on 06-09 Jul.  Geomagnetic field activity was at quiet levels on 03 Jul to midday on 05 Jul. Quiet to unsettled levels were observed from midday 05 Jul to 07 Jul, with isolated active intervals from midday on 07 Jul to early on 08 Jul. This activity was the result of weak transient activity coupled with positive polarity CH HSS. The majority of 08 Jul through 09 Jul observed quiet conditions. 

Forecast of Solar and Geomagnetic Activity 10 July - 05 August 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 be at high levels throughout the forecast period. 

Geomagnetic field activity is expected to reach unsettled levels on 10-11 Jul and 03-04 Aug due to positive polarity CH HSS influence. Unsettled to active levels are expected on 13-14 Jul due to negative polarity CH HSS influence. Mostly quiet levels are expected on 12, 15-31 Jul, 01-02 and 05 Aug.
