Highlights of Solar and Geomagnetic Activity 20 - 26 May 2019
Solar activity was very low. No sunspots were observed on the solar disk and no Earth-directed CMEs were observed in available coronagraph imagery.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at normal levels on 20-21 May and normal to moderate levels on 22-26 May.
Geomagnetic field activity was at quiet to unsettled on 20 May and 26 May. The remainder of the reporting period was quiet.
Forecast of Solar and Geomagnetic Activity 27 May - 22 June 2019
Solar activity is expected to be very low 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 range from normal to high levels. High levels are expected on 29 May - 02 Jun and moderate levels are expected on
03-12 Jun. Enhancements in electron flux are due to the anticipated influence of multiple CH HSSs. The remainder of the outlook period is expected to be at normal background levels.
Geomagnetic field activity is expected to range from quiet to active levels. Early on 27 May, unsettled to active levels are possible due to weak enhancements in the solar wind. Negative polarity CH HSS influence is expected to produce unsettled to active conditions from 28-30 May and quiet to unsettled conditions from 31 May-02 Jun. The remainder of the outlook period is expected to be mostly quiet under nominal solar wind conditions.
