=================================== Weekly Space Weather Highlights =================================== 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.
