Highlights of Solar and Geomagnetic Activity 13 - 19 July 2020
Solar activity was very low throughout the period. No active regions with sunspots were observed over the past week. The passage of a slow-moving CME from 08 Jul was observed on 13-14 Jul. Near the end of the period, a faint, slow-moving CME was observed off the western limb in STEREO-A imagery beginning at around 19/0524 UTC. Analysis of this event remains underway at the time of this writing.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at normal-to-moderate levels throughout the period.
Geomagnetic field activity reached active levels between 13/0000-0900 UTC due to a combination of positive polarity CH HSS and CME (08 Jul) effects. Quiet to unsettled conditions were observed on 13 Jul. Quiet conditions were observed throughout the remainder of the period.
Forecast of Solar and Geomagnetic Activity 20 July - 15 August 2020
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 be normal-to-moderate throughout the outlook period.
Geomagnetic field activity is expected to be quiet to unsettled on 23-24 Jul and 31 Jul-01 Aug. Quiet conditions are expected to prevail throughout the rest of the period.
