Highlights of Solar and Geomagnetic Activity
24 - 30 October 2022
Solar activity was at low levels during the period. Weak to moderate
levels of C-class activity was observed from Regions 3126 (S10,
L=233, class/area Dai/160 on 25 Oct), 3130 (S25, L=185, class/area
Dao/090 on 27 Oct), 3131 (N23, L=111, class/area Cso/190 on 27 Oct),
3133 (N26, L=095, class/area Dao/140 on 28 Oct) and 3135 (N27,
L=063, class/area Eao/160 on 30 Oct). No Earth-directed CMEs were
detected during the period.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at
normal to moderate levels on 24-29 October. High levels were
observed on 30 Oct with a peak flux of 3,715 pfu observed at 30/1735
UTC.
Geomagnetic field activity was at quiet to G1 (Minor) storm levels
during the period. Quiet to unsettled levels were observed from
24-27 October. Activity levels increased to unsettled to active on
28 October, unsettled to G1 (Minor) storm levels on 29 October and
quiet to active levels on 30 October. The increase in activity on
28-30 October was due to positive polarity coronal high speed stream
effects.
Forecast of Solar and Geomagnetic Activity
31 October - 26 November 2022
Solar activity is expected to be at very low to low levels on 31 Oct
- 02 Nov and 18 - 26 Nov. There is a slight chance for M-class
activity on 03 - 17 Nov due to the return of previously active
regions with M-class flare history.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at moderate to high levels on 31 Oct - 09 Nov and 26
Nov. Low to moderate levels are expected on 10 - 25 Nov.
Geomagnetic field activity is expected to be at unsettled to active
levels on 31 Oct - 06 Nov, 10-12 Nov, 18-19 Nov and 24-26 Nov. G1
(Minor) geomagnetic storm levels are possible on 05, 18 and 25 Nov.
This elevated level of activity is in anticipation of mulitple,
recurrent CH HSSs. The remainder of the outlook period is likely to
be at mostly quiet levels.
