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 Jan.

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 enhnacements.
