Highlights of Solar and Geomagnetic Activity 30 July - 05 August 2018
Solar activity was very low throughout the period. Region 2717 (S08, L=027, class/area=Axx/10 on 02 Aug) was briefly the sole active region with sunspots, but was largely unproductive. No
Earth-directed CMEs were observed this period.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit reached high levels on 30 Jul, moderate levels on 31 Jul, and 01, 03-04 Aug. Normal levels were observed throughout the rest of the period. Geomagnetic field activity was quiet to unsettled on 31 Jul, and 01-03 Aug, with quiet conditions observed throughout the remainder of the period, under a nominal solar wind environment.
Forecast of Solar and Geomagnetic Activity 06 August - 01 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 reach high levels on 21-26 Aug. Moderate levels are expected on 06-11, 18-20, 27-31 Aug and 01 Sep. Normal levels are expected throughout the remainder of the outlook period. Geomagnetic field activity is likely to reach G1 (Minor) geomagnetic storm levels on 20 Aug due to the influence of a negative polarity, coronal hole high-speed stream. Active conditions are expected on 07-08, 17, and 20-21 Aug due to multiple, recurrent coronal hole high-speed streams. Quiet to unsettled conditions are expected throughout the remainder of the outlook period.
