Highlights of Solar and Geomagnetic Activity
12 - 18 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
high levels on 12-17 Aug with moderate levels on 18 Aug. A maximum
flux of 5,340 pfu was observed at 13/1725 UTC. 

Geomagnetic field activity was at predominately quiet levels with
isolated unsettled intervals observed midday on 16 Aug and early on
18 Aug. Solar wind parameters reflected a nominal environment
through the period. 

Forecast of Solar and Geomagnetic Activity
19 August - 14 September 2019

Solar activity is expected to continue at very low levels through
the oulook period. 

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be normal to moderate levels on 19 - 31 Aug. Flux
readings are expected to increase to moderate to high levels on 01 -
14 Sep.due to recurrent CH HSS influence. 

Geomagnetic field activity is expected to reach unsettled levels on
20 - 22 Aug, 26 - 28 Aug and 06 - 07 Sep due to recurrent CH HSS
activity. Active to G1 (minor) storm conditions are likely on 01 -
02 Sep due to recurrent CH HSS activity.
