Highlights of Solar and Geomagnetic Activity 01 - 07 October 2018

Solar activity was very low this period. Region 2723 (S08, L=357,  class/area=Dso/30 on 01 Oct) was the only active region with sunspots, but was quiet throughout the period. No Earth-directed
CMEs were observed during the summary period.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at moderate levels throughout the period.

Geomagnetic field activity reached G1 (Minor) geomagnetic storm levels on 07 Oct due to the influence of a positive polarity CH HSS. Active conditions were observed on 01-02 Oct and quiet to unsettled levels were observed on 03, and 05-06 Oct. Quiet conditions prevailed on 04 Oct.

Forecast of Solar and Geomagnetic Activity 08 October - 03 November 2018

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 08-25 Oct with moderate flux levels expected throughout the remainder of the outlook period.

Geomagnetic field activity is expected to reach G1-G2 (Minor-Moderate) geomagnetic storm levels on 08 Oct and 03 Nov due to the influence of a positive polarity CH HSS. G1 (Minor) geomagnetic storm levels are expected on 19 Oct and active levels are expected on 09-10, 18, 20, and 22 Oct, due to the influence of multiple, recurrent CH HSSs.
