Summary For October 26-November 1

R1 (Minor) radio blackouts were observed on 31 October from flare activity from active Region 2443.

Outlook For November 2-8

R1 (Minor) radio blackouts are likely through the outlook period due to potential flare activity from active Region 2443 and the return of old active Region 2434 on 07 November.

G1 (Minor) and G2 (Moderate) geomagnetic storm are likely on 02-03 November while G3 (Strong) geomagnetic storms are likely on 02 November. This activity is likely in response to a recurrent, trans-equatorial coronal hole high speed anticipated to become geoeffective early to midday on 02 November.
