Highlights of Solar and Geomagnetic Activity 06 - 12 February 2017

Solar activity reached low levels on 09 Feb due to C-class flare
activity from Region 2635 (N14, L=304, class/area=Dai/110 on 10
Feb). Solar activity was at very low levels throughout the remainder
of the period and no Earth-directed coronal mass ejections (CMEs)
were observed.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached
high levels each day of this period.

Geomagnetic field activity was at quiet to active levels on 06 Feb,
quiet to unsettled levels on 07, 10-11 Feb, and quiet throughout the
remainder of the period.

FORECAST OF SOLAR AND GEOMAGNETIC ACTIVITY 13 FEBRUARY - 11 MARCH 2017

Solar activity is expected to be at very low levels with a slight
chance for isolated C-class flare activity throughout the 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 13, 16-18, 22-26, 28 Feb, and 01-11
Mar. Normal to moderate flux levels are expected for the remainder
of the period.

Geomagnetic field activity is expected to reach G2 (Moderate)
geomagnetic storm levels on 28 Feb and G1 (Minor) storm levels on 27
Feb, 01-02 Mar due to recurrent coronal hole high speed stream
influence. Active geomagnetic field activity is expected on 15, 23
Feb, and 03-04 Mar. Quiet and quiet to unsettled geomagnetic
activity is expected for the remainder of the period under a nominal
solar wind regime.
