Highlights of Solar and Geomagnetic Activity 07 - 13 May 2018
Solar activity was very low throughout the period and no reportable events were observed.
No proton events were observed at geosynchronous orbit. The greater than 2 MeV electron flux at geosynchronous orbit reached very high levels on 9-11 May and high levels were observed throughout the remainder of the period.
Geomagnetic field activity was at quiet to active levels on 07-09, 11-12 May due to the influence of a negative polarity coronal hole/high speed solar wind stream. Quiet to unsettled levels were
observed on 10 May, and conditions were quiet on 13 May.
Forecast of Solar and Geomagnetic Activity 14 May - 09 June 2018
Solar activity is expected to persist 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 very high levels on 05-07 Jun with high levels expected on 14-26 May and 02-04, 08-09 Jun. Moderate flux levels are likely though the remainder of the outlook period.
Geomagnetic field activity is expected to reach G2 (Moderate) geomagnetic storm levels on 02 Jun with G1 (Minor) geomagnetic storms levels expected on 17 May and 01 Jun due to the influence of
multiple coronal hole/high speed solar wind streams. Active conditions are expected on 18 May and 03-05 Jun and generally quiet or quiet to unsettled conditions are expected to prevail for the
remainder of the outlook period.
