Here is this week’s space weather and geophysical report, issued 2019 Aug 19 0141 UTC.

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.
