Highlights of Solar and Geomagnetic Activity 24 - 30 December 2018

Solar activity was very low throughout the period. 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 on 29-30 December, with moderate levels on 24-25, and 28 December. Normal levels were observed on 26-27 December.

Geomagnetic field activity reached G1 (Minor) storm levels on 28 December and quiet to unsettled levels on 27, 29-30 December in response to recurrent CH HSS infleunce. Quiet conditions prevailed
on 24-26 December.

Forecast of Solar and Geomagnetic Activity 31 December - 26 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 31 December, 01-03, 06-12, and 25-26 January with moderate flux levels expected on 04-05, 13-21,
and 24 January. Normal levels are expected throughout the remainder of the period.

Geomagnetic field activity is expected to reach G1 (Minor) storm levels on 24 January, with active levels expected on 04-06, and 16 January due to recurrent CH HSS effects. Quiet to unsettled
conditions are expected throughot the remainder of the outlook period.
