Highlights of Solar and Geomagnetic Activity 25 - 31 December 2017
Solar activity was very low throughout the period. Region 2692 (N18, L=087, class/area=Eai/160 on 24 Dec) was the only numbered active region this period, but the region was without sunspots and
unproductive through most of the week. 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 27 and 29 Dec with moderate levels observed through the remainder of the period.
Geomagnetic field activity reached active levels on 26 Dec due to the influence of a negative polarity CH HSS. Quiet and quiet to unsettled levels were observed throughout the rest of the week.
Forecast of Solar and Geomagnetic Activity 01 January - 27 January 2018
Solar activity is expected to be at very low levels 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 02-06, 14-19, and 23-24 Jan. Moderate flux levels are expected through the rest of the outlook period.
Geomagnetic field activity is likely to reach G1 (Minor) geomagnetic storm levels on 01 and 13 Jan, with active periods likely on 02, 08, 14, 20 and 27 Jan, due to the effects of multiple, recurrent CH HSSs. Quiet and quiet to unsettled geomagnetic field activity is expected throughout the remainder of the outlook period.
