Highlights of Solar and Geomagnetic Activity
06 - 12 August 2018

Solar activity was very low throughout the period. No Earth-directed
CMEs were observed in available satellite imagery. 

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was
normal background levels throughout the period. 

Geomagnetic field activity was ranged from quiet to active. Quiet
levels were observed on 06 Aug, 08-10 Aug and 12 Aug; unsettled
levels were reached on 07 Aug and active levels were reached on 11
Aug. Mostly nominal solar wind conditions were observed through the
period. A SSBC followed by very weak influence from a negative
polarity CH HSS occurred on 11 Aug. Total magnetic field strength
briefly reached 11 nT around 11/0400 UTC but no significant periods
of southward Bz were observed. 

Forecast of Solar and Geomagnetic Activity
13 August - 08 September 2018

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 moderate levels over the outlook
period. 

Geomagnetic field activity is expected to range from quiet to active
levels over the outlook period. Unsettled levels are expected on 13
Aug, 18 Aug, 04 Sep and 07-08 Sep; active levels are expected on
16-17 Aug, 20-21 Aug and 03 Sep. All increases in geomagnetic
activity are anticipated in response to multiple, recurrent CH HSSs.
The remainder of the outlook period is expected to be at quiet
levels.
