Highlights of Solar and Geomagnetic Activity 18 - 24 December 2017
Solar activity was at very low levels throughout the period. Region 2692 (N18, L=087, class/area=Eai/160 on 24 Dec) was the only active region with sunspots this period and produced multiple low and mid-level B-class flares throughout the week. No Earth-directed CMEs were observed. No proton events were observed at geosynchronous orbit.The greater than 2 MeV electron flux at geosynchronous orbit reached high levels on 18-23 Dec with moderate levels observed on 24 December.
Geomagnetic field activity reached active levels early on 18 Dec in response to the influence of a recurrent, positive polarity CH HSS. Quiet to unsettled conditions were observed on 19 and 23-24 Dec and generally quiet conditions were observed throughout the remainder of the week under a nominal solar wind regime.
Forecast of Solar and Geomagnetic Activity 25 December - 20 January 2018
Solar activity is expected to persist at very low levels throughout the 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 26-30 Dec, 02-06 and 14-19 Jan. Normal and normal to moderate greater than 2 MeV electron flux values are expected throughout the remainder of the forecast period. Geomagnetic field activity is likely to reach G1 (Minor) geomagnetic storm levels on 01 and 13 Jan with active levels expected on 25 Dec and 02, 08, 14 and 20 Jan under the influences of multiple, recurrent CH HSSs. Quiet and quiet to unsettled conditions are expected throughout the remainder of the forecast period.
