Here is this week's space weather and geophysical report, issued 2022 Jul 04 0139 UTC.

Highlights of Solar and Geomagnetic Activity 27 June - 03 July 2022

Solar activity was at very low to low levels during the period. Low levels were observed on 27 and 30 Jun and 03 Jul with C-class activity observed from Region 3040 (S13, L=325, class/area Cso/160 on 24 Jun). Late on 28 Jun, an 11 degree filament erupted along a channel centered near N23E20. LASCO C2 imagery observed a narrow CME off the W limb with an apparent Earth-directed component.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at high levels on 27-30 Jun and 01 Jul with a maximum flux value of 6,970 pfu observed at 01/1720 UTC. Normal to moderate levels were observed on 02-03 Jul.

Geomagnetic field activity was at quiet to G1 (Minor) storm levels during the period. Unsettled to active levels were observed on 27-28 Jun due to negative polarity CH HSS effects. Quiet levels were observed on 29-30 Jun. Unsettled to active levels were observed on 01-03 Jul, with an isolated G1 (Minor) storm interval observed early on 02 Jul due to CME effects from the 28 Jun DSF.

Forecast of Solar and Geomagnetic Activity 04 July - 30 July 2022

Solar activity is expected to be at very low to low levels through the outlook 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 on 08-13, 16-21 and 24-30 Jul due to CH HSS influence. Normal to moderate levels are expected on 04-07, 14-15 and 22-23 Jul.

Geomagnetic field activity is expected to be at unsettled levels on 05-08, 14-17 and 22-25 Jul with active intervals likely on 06-07, 15-16, and 22-23 Jul and G1 (Minor) storm levels are likely on 06 Jul, all due to recurrent CH HSS activity.
