Highlights of Solar and Geomagnetic Activity 01 - 07 January 2018 Solar activity was very low throughout the reporting period. Region 2693 (N18, L=333, class/area=Cro/20 on 04 Jan) was the only numbered sunspot region on the visible disk but it was inactive and absent of significant flare activity. No Earth-directed coronal mass ejections were observed during the period. No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached moderate levels on 01 January with normal levels observed throughout the remainder of the period (02-07 Jan). Geomagnetic field activity reached active levels on 01 January due to the influence of a positive polarity coronal hole high-speed stream. Quiet conditions were observed throughout the rest of the period (02-07 Jan).

Forecast of Solar and Geomagnetic Activity 08 January - 03 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 14-19, 23, and 25 January in response to recurrent coronal hole high-speed stream influence. Normal to moderate levels are expected throughout the remainder of the outlook period.  Geomagnetic field activity is expected to reach active levels on 08, 15, and 20 January due to the anticipated effects of recurrent coronal hole high-speed streams. Quiet to unsettled geomagnetic field activity is expected throughout the remainder of the outlook period.
