Highlights of Solar and Geomagnetic Activity 03 - 09 August 2020
Solar activity was at very low levels on 03-07 and 09 Aug. Low levels were reached on 08 Aug as Region 2770 (N23, L=023, class/area Cso/070 on 06 Aug) produced an isolated C1/Sn flare at 08/0349 UTC. This was the first C-class flare observed since 29 May. No Earth-directed CMEs were observed.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at moderate to high levels. Moderate levels were observed on 03-04 Aug. High levels were observed on 05-09 Aug due to coronal hole high speed stream (CH HSS) influence. The maximum flux of the period was
2,815 pfu observed at 05/1630 UTC.
Geomagnetic field activity ranged from quiet to active levels. The period began with the onset of a positive polarity CH HSS. Total field reached 10 nT at the beginning of the period and the solar wind speed reached a maximum of 754 km/s at 04/0516 UTC. By early on 05 Aug, solar wind speed was in decline and nominal background levels returned by 07 Aug. The geomagnetic field responded with quiet to active levels on 03-04 Aug and quiet conditions on 05-09 Aug.
Forecast of Solar and Geomagnetic Activity
10 August - 05 September 2020
Solar activity is expected to be very low levels with a slight chance for isolated C-class flares through 15 Aug. Very low levels are expected for the rest of 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 10-11 Aug and again on 01-05 Sep due to CH HSS influence.
Geomagnetic field activity is expected to be reach unsettled levels on 29-31 Aug with active levels likely on 30 Aug due to recurrent CH HSS effects.
