Highlights of Solar and Geomagnetic Activity
03 - 09 December 2018

Solar activity was very low throughout the period. Region 2729 (S05,
L=229, class/area=Cro/50 on 06 Dec) was the only region with
sunspots and produced multiple low-level B-class flare late in the
period. A CME associated with a filament eruption on 30 Nov was
predicted to hit Earth on 05 Dec, but this event did not
materialize.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached
moderate levels on 06, and 08-09 Dec and normal levels were observed
throughout the remainder of the period.

Geomagnetic field activity reached active levels late on 09 Dec in
response to coronal hole/high speed stream effects. Quiet and quiet
to unsettled conditions were observed throughout the remainder of
the period.

Forecast of Solar and Geomagnetic Activity
10 December - 05 January 2019

Solar activity is expected to be very low 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 moderate levels on 10-16 Dec and 03-05 Jan with
normal flux levels expected for the remainder of the outlook period.

Geomagnetic field activity is expected to reach active levels on 10
Dec and 29 Dec due to coronal hole/high speed stream effects. Quiet
or quiet to unsettled conditions are expected throughout the
remainder of the outlook period.
