-G1 (Minor) geomagnetic storms were observed on 29 Sep-03 Oct, G2 (Moderate) storms were observed on 30 Sep-02 Oct, and G3 (Strong) storms were observed on 30 Sep and 02 Oct, due to CH HSS and CME influences.

-No additional space weather storms were observed during the summary period.

Outlook For October 6-12
