Highlights of Solar and Geomagnetic Activity 19 - 25 August 2019

Solar activity was very low. The visible disk was spotless with no Earth-directed CMEs observed.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at moderate levels throughout the forecast period. Geomagnetic field activity was at quiet levels under nominal solar wind conditions throughout the forecast period.

Forecast of Solar and Geomagnetic Activity 26 August - 21 September 2019

Solar activity is expected to remain 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 reach high levels on 02-13 Sep due to recurrent CH HSS influence. Moderate levels are expected thought out the remainder of the period.

Geomagnetic field activity is likely to reach G2 (Moderate) geomagnetic storm levels on 01 Sep, active levels on 26-27 Aug, 02 Sep, with unsettled levels on 28 Aug, 03, 06-07 Sept is due to recurrent CH HSS effects.
