Highlights of Solar and Geomagnetic Activity 19 - 25 June 2017

Solar activity was very low throughout the period with only isolated
low and mid-level B-class flare activity observed. Regions 2663
(N12, L=095, class/area=Dso/100 on 17 Jun) and 2664 (N18, L=314,
class/area=Cso/90 on 25 Jun) each produced B-class flare activity
throughout the week while Region 2662 (N12, L=050,
class/area=Hsx/170 on 13 Jun) was quiet. No Earth-directed CMEs were
observed this period.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached
high levels on 19-21 Jun with moderate levels observed on 22-25 Jun.

Geomagnetic field activity was generally quiet and quiet to
unsettled throughout the week with isolated active conditions
observed on 25 Jun due to the influence of a positive, north
polar-connected CH HSS.

FORECAST OF SOLAR AND GEOMAGNETIC ACTIVITY 26 JUNE - 22 JULY 2017

Solar activity is expected to be very low, with a slight chance for
C-class flare activity, 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 30 Jun-03 Jul, and 16-18 Jul.
Normal and normal to moderate flux levels are expected to prevail
throughout the remainder of the outlook period.

Geomagnetic field activity is expected to be at quiet and quiet to
unsettled levels through most of the outlook period; however, G1
(Minor) geomagnetic storm conditions are likely on 13 Jul with
active conditions likely on 14 Jul due to the anticipated influence
of a recurrent, negative polarity CH HSS.
