Highlights of Solar and Geomagnetic Activity
02 - 08 December 2024

Solar activity reached high levels on 08 Dec when Region 3912 (S07,
L=80, class/area=Dai/220 on 07 Dec) produced an impulsive X2.2/2b
flare at 08/0906 UTC; the largest event of the period. Associated
with the X2.2 flare was a Castelli-U radio burst, a 870 sfu
Tenflare, and a 360 sfu Type-II radio sweep. Regions 3912 and 3917
(S07, L=09, class/area=Dac/210 on 08 Dec) produced the bulk of the
M-class flares (R1-Minor events) observed over the course of the
week. No Earth-directed CMEs were detected as a result of this
week's activity. 

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at
normal to moderate levels throughout the period. 

Geomagnetic field activity reached active levels on 03 Dec due to
the passage of a CME from 27 Nov. Quiet and quiet to unsettled
levels were observed throughout the remainder of the period. 

Forecast of Solar and Geomagnetic Activity
09 December - 04 January 2025

Solar activity is likely to reach moderate levels. M-class flares
(R1-R2/Minor-Moderate) are likely, with a slight chance for X-class
flares (R3-Strong or greater), throughout much of the outlook
period. 

No proton events are expected at geosynchronous orbit; barring
significant flare activity. 

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at normal to moderate levels throughout the outlook
period. 

Geomagnetic field activity is expected to be quiet and unsettled
over 09-14 Dec due to positive polarity CH HSS influences. Quiet and
unsettled conditions are likely over 16-20 Dec, with active
conditions possible on 19 Dec, due to negative polarity CH HSS
influences.
