#Weekly Highlights and Forecasts
Highlights of Solar and Geomagnetic Activity 03 - 09 June 2019
Solar activity was at very low levels. No sunspots were observed on the visible disk and there was an absence of significant flare activity. A dissapearing solar filament (DSF), centered near S05E52, was observed in GONG optical imagery at 03/0715 UTC but was not observed in LASCO imagery. This CME was believed to have impacted Earth midday on 08 June. An additional DSF, centered near S05E13, was observed at 07/2145 UTC and is expected to have a possible geoeffective component with an anticipated arrival of 12 June.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit reached high levels on 03 June and moderate levels on 04-08 June in response to elevated wind speeds from a negative polarity, coronal hole high-speed stream (CH HSS). The peak electron flux during the reporting period was 2,270 pfu at 03/1755 UTC.
