Highlights of Solar and Geomagnetic Activity 22 - 28 January 2018
Solar activity was at very low levels. The largest event of the period was a B9 flare from plage Region 2696 (S13, L=123). 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 normal levels on 22-25 Jan and moderate levels from 26-28 Jan. A maximum flux of 348 pfu was observed at 27/2010 UTC. Geomagnetic field activity was at predominately quiet to unsettled levels with an isolated active interval observed late on 24 Jan. Quiet to unsettled periods were observed on 22 Jan and 24-26 Jan due to a pair of weak negative polarity CH HSS. Quiet levels were observed on 23 Jan and 27- 28 January.

Forecast of Solar and Geomagnetic Activity 29 January - 24 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 be at normal to moderate levels throughout the outlook period.

Geomagnetic field activity is expected to be at quiet to unsettled levels on 29-31 Jan, 04-05 Feb, 09-11 Feb, 15-18 Feb and 20-22 Feb, with isolated active periods likely on 10 Feb. This activity is due
to influence from recurrent CH HSSs. Mostly quiet conditions are expected for the remainder of the outlook period.
