Highlights of Solar and Geomagnetic Activity 23 - 29 September 2019

Solar activity was very low throughout the summary period and no active regions with sunspots were observed.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached very high levels on 29 Sep with high levels observed on 28 Sep. Normal and normal to moderate flux values were observed throughout the remainder of the week.

Geomagnetic field activity reached G1 (Minor) geomagnetic storm levels on 27-28 Sep due to the influence of a recurrent, positive polarity coronal hole high speed stream (CH HSS). The active conditions were observed on 24 and 29 Sep and quiet or quiet to unsettled conditions were observed throughout the remainder of the period.

Forecast of Solar and Geomagnetic Activity 30 September - 26 October 2019

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 reach high levels on 30 Sep-12, 14, and 25-26 Oct. Normal and normal to moderate levels are expected for the remainder of the outlook period.

Geomagnetic field activity is expected to reach G1 (Minor) geomagnetic storm levels on 24-25 Oct and active levels on 06, 21, and 26 Oct due to coronal hole high speed stream influences.
