Highlights of Solar and Geomagnetic Activity 08 - 14 January 2018

Solar activity was very low throughout the summary period. Regions
2694 (S32, L=244, class/area=Axx/10 on 10 Jan) and 2695 (S08, L=260,
class/area=Bxo/10 on 11 Jan) briefly contained sunspots and simple
magnetic signatures early this period, but both regions were
generally quiet and unproductive. No Earth-directed CMEs were
observed.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit
remained at normal flux levels throughout the summary period.

Geomagnetic field activity reached G1 (Minor) geomagnetic storm
levels early on 14 Jan with isolated active periods observed on 08,
09 and 14 Jan due to the influences of multiple positive polarity CH
HSSs. Generally quiet and quiet to unsettled geomagnetic field
activity was observed throughout the remainder of the summary
period.

FORECAST OF SOLAR AND GEOMAGNETIC ACTIVITY 15 JANUARY-10 FEBRUARY 2018

Solar activity is expected to prevail 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 15-19 and 23-25 Jan and moderate
levels are expected on 20-22 and 26-28 Jan. Normal flux levels are
expected to prevail through the remainder of the outlook period.

Geomagnetic field activity is expected to reach G1 (Minor)
geomagnetic storm levels on 19-20 Jan with active levels expected on
21 Jan due to the influence of a recurrent, negative polarity CH
HSS. Generally quiet and quiet to unsettled conditions are expected
throughout the remainder of the outlook period.
