Highlights of Solar and Geomagnetic Activity 15 - 21 January 2018
Solar activity was at very low levels with a few B-class flares observed from Region 2696 (S13, L=123, class/area Cro/030 on 16 Jan). No Earth-directed CMEs were observed. No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at moderate levels on 15-18 Jan with a maximum flux of 273 pfu observed at 18/1925 UTC. Normal levels were observed on 19-21 January.
Geomagnetic field activity was at quiet to active levels on 15 Jan, quiet levels on 16-18 Jan and quiet to unsettled levels on 19-21 Jan. The field was influenced on 15 Jan by waning positive polarity
CH HSS influence. On 19-21 Jan, a pair of negative polarity CH HSSs resulted in weak geomagnetic field enhancements.
Forecast of Solar and Geomagnetic Activity 22 January - 17 February 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 24-25 Jan; moderate levels on 22-23 Jan, 26-28 Jan and 11-15 Feb; and normal levels for the remainder of the outlook period. Geomagnetic field activity is expected to be at unsettled to active levels on 22-24 Jan, 28 Jan, 04-05 Feb, 09-11 Feb and 15-17 Feb, all
due to influence from recurrent CH HSSs. Mostly quiet conditions are expected for the remainder of the outlook period.
