Highlights of Solar and Geomagnetic Activity 10 - 16 December 2018

Solar activity was very low throughout the period. Region 2731 (N13, L=023, class/area=Bxo/10 on 14 Dec) maintained sunspots for two days before decaying to plage and produced an isolated B1 flare at 15/1353 UTC. No Earth-directed CMEs were observed this period.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached high levels each day this period.

Geomagnetic field activity was quiet to unsettled on 10-11 Dec with quiet conditions observed throughout the remainder of the period.

Forecast of Solar and Geomagnetic Activity 17 December - 12 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 high levels on 08-12 Jan with moderate flux levels expected on 17-21 Dec and 03-05 Jan. Normal levels are expected
throughout the remainder of the outlook period.

Geomagnetic field activity is expected to reach active levels on 29 Dec and 04 Jan due to CH HSS effects. Quiet to unsettled or generally quiet conditions are expected throughout.
