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.

Geomagnetic field activity reached G1 (Minor) storm levels on 08
June and unsettled levels on 09 June as a result of the
aforementioned 03 June CME. Quiet conditons were observed throughout
the remainder of the period.

Forecast of Solar and Geomagnetic Activity
10 June – 06 July 2019

Solar activity is expected to be at very low levels 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 11-13 and 26-30 June, with moderate
levels expected on 10, 14-20, 25 June and 01-03 July in response to
elevated wind speeds associated with recurrent CH HSS activity.

Geomagnetic field activity is expected to reach active levels on 12
and 25 June, unsettled levels on 10-11, 13, 24, 26 June and 06 July
due to CH HSS influence. Quiet conditions are expected throughout
the remainder of the outlook period.
