Highlights of Solar and Geomagnetic Activity 23 - 29 September 2024
Solar activity reached moderate levels on 23, 25-26, and 29 Sep with a total of six R1 (Minor) events observed throughout the week. Low levels of solar activity and C-class flare activity were observed throughout the remainder of the period. The largest events of the period were a pair of M1.7 flares from Region 3842 (S15, L=178, class/area=Dai/230 on 29 Sep) at 29/1424 and 1441 UTC. No Earth-directed CMEs resulted from this week's solar activity.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit reached high levels on 23 Sep, and normal to moderate levels on 24-29 Sep.
Geomagnetic field activity reached active levels on 23 and 26 Sep, and G1 (Minor) storm levels on 24-25 Sep, due to the passage of CMEs (23-25 Sep) and the influence of a positive polarity CH HSS (25-26 Sep). Quiet to unsettled conditions were observed over 27-29 Sep.
Forecast of Solar and Geomagnetic Activity 30 September - 26 October 2024
Solar activity is expected to range from low to moderate levels. R1-R2 (Minor-Moderate) events are likely, with a slight chance for R3 or greater events, throughout the period.
No proton events are expected at geosynchronous orbit, barring significant flare activity.
The greater than 2 MeV electron flux at geosynchronous orbit is likely to reach high levels on 12-15 Oct, with normal to moderate levels likely to persist throughout the remainder of the period.
Geomagnetic field activity is likely to reach active levels on 30 Sep due to negative polarity CH HSS influences. Active levels are likely on 05-06, and 10 Oct due to positive polarity CH HSS influences. Periods of G1 (Minor) storming are likely on 11-12, and 22 Oct due to positive polarity CH HSS influences.
