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.
