Highlights of Solar and Geomagnetic Activity 14 - 20 May 2018
Solar activity was very low throughout the period and no events were reported. No Earth-directed CMEs were observed. No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached high levels on 14-17 May with moderate levels observed on 18-20 May. Geomagnetic field activity was quiet to unsettled on 17 May due to the influence of a negative polarity coronal hole/high speed stream. Quiet conditions were observed throughout the remainder of the period.

Forecast of Solar and Geomagnetic Activity 21 May - 16 June 2018

Solar activity is expected to be very low 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 very high levels on 05-07 Jun with high levels expected on 02-04 and 08-13 Jun. Moderate flux levels are expected for the remainder of the outlook period.

Geomagnetic field activity is expected to reach G2 (Moderate) geomagnetic storm levels on 02 Jun and G1 (Minor) storm levels are expected on 01 Jun due to the influence of a recurrent, negative polarity coronal hole/high speed stream. Active conditions are expected on 23 May and 03-05 Jun.
