Highlights of Solar and Geomagnetic Activity 23 - 29 October 2023
Solar activity reached moderate levels on 26 Oct due to an M1.4 flare at 26/2324 UTC from the SE limb; the largest event of the period. Low levels of solar activity and C-class flares were observed throughout the remainder of the week. No Earth-directed CMEs were observed.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at normal to moderate levels over 23-28 Oct, with high levels observed on 29 Oct following a prolonged period of increased geomagnetic field activity and enhanced solar wind conditions.
Geomagnetic field activity was at quiet levels with ambient solar wind conditions observed over 23-25 Oct. The effects of a CIR followed by positive polarity CH HSS influences produced periods of G1 (Minor) storm conditions on 26 Oct, and active conditions on 27 Oct. The onset of another CIR followed by positive polarity CH HSS influences resulted in active conditions on 28 Oct, and periods of G1 (Minor) storms on 29 Oct.
Forecast of Solar and Geomagnetic Activity 30 October - 25 November 2023
Solar activity is expected to be at low levels with a varying chance for M-class (R1-R2) flare activity throughout the outlook 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 30 Oct-05 Nov and 25 Nov. Normal to moderate flux levels are expected throughout the remainder of the period.
Geomagnetic field activity is expected to reach G1 (Minor) storm levels on 30 Oct, and active levels on 31 Oct, in response to positive polarity CH HSS influences. Active conditions are expected on 09 Nov due to negative polarity CH HSS influences. Positive polarity CH HSS effects are expected to result in active levels on 22 and 24-25 Nov. Quiet and quiet to unsettled conditions are expected throughout the remainder of the outlook period.
