Highlights of Solar and Geomagnetic Activity 12 - 18 June 2017

Solar activity was very low throughout the period. Regions 2661
(N06, L=211, class/area=Dao/200 on 02 Jun) and 2663 (N12, L=095,
class/area=Dso/100 on 17 Jun) were the most prominent regions this
period, but only produced low and mid-level B-class flare activity.
No Earth-directed CMEs were observed during the period.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at
normal levels on 12-16 Jun with moderate levels observed on 17-18
Jun.

Geomagnetic field activity reached G1 (Minor) geomagnetic storm
levels on 16 Jun and active levels on 17 Jun due to the influence of
a recurrent negative polarity CH HSS. Geomagnetic field activity was
at quiet or quiet to unsettled levels throughout the remainder of
the period.

FORECAST OF SOLAR AND GEOMAGNETIC ACTIVITY 19 JUNE - 15 JULY 2017

Solar activity is expected to be very low throughout the outlook
period with a slight chance for C-class flare activity.

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 19-22 and 25-27 Jun with normal and
moderate flux levels expected throughout the remainder of the
period.

Geomagnetic field activity is likely to reach G1 (Minor) geomagnetic
storm levels on 13 Jul with active levels likely on 23-24 Jun, and
14 Jul due to the influence of multiple, recurrent CH HSSs.
Generally quiet and quiet to unsettled activity is expected
throughout the remainder of the period as a nominal solar regime
prevails.
