Highlights of Solar and Geomagnetic Activity 10 - 16 August 2020
Solar activity was at very low levels on 10-14 and 16 Aug. Low levels were observed on 15 Aug due to a C2 flare from Region 2770 (N23, L=24, class/area Cso/70 on 07 Aug.
Coronal dimming near S30E30 was observed in GOES-16 SUVI 195 imagery around 16/1700 UTC. An associated CME signature was observed in LASCO C2 imagery at 16/1812 UTC and in the STEREO-A COR2 coronagraph imagery beginning at 16/1824 UTC. Analysis of this event remains underway at the time of this writing. No other Earth-directed CME activity was detected during the period.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at high levels on 10-11 Aug due to coronal hole high speed stream influence. The maximum flux of the period was 2,950 pfu and observed at 10/1550 UTC. Normal to moderate levels were observed on 12-16 Aug.
Geomagnetic field activity was at quiet levels throughout the period.
Forecast of Solar and Geomagnetic Activity 17 August - 12 September 2020
Solar activity is expected to be at very low levels throughout the 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 01-07 Sep due to recurrent coronal hole high speed stream influence. Normal to moderate levels are expected for the remainder of the outlook period. Geomagnetic field activity is expected to be unsettled to active on 30 Aug, unsettled on 19-20 Aug and 29, 31 Aug-all due to recurrent coronal hole high speed stream influence. Quiet levels are also expected for the remainder of the outlook period.
