**** SPACE WEATHER OUTLOOK ****

Summary For August 12-18

R1 (Minor) radio blackouts were observed on 12 Aug and 17 Aug due to flare activity from active Regions 1817 and 1818 respectively.

G1 (Minor) geomagnetic storms were observed on 16 Aug due to effects from a coronal hole high speed stream (CH HSS).

Outlook For August 19-25

A chance for R1 – R2 (Minor – Moderate) radio blackouts exists from 19 – 21 Aug due to possible continued flare activity from Region 1818.

A slight chance for a G1 (Minor) geomagnetic storm exists on 21 Aug due to a combination of CH HSS effects and possible effects from the 17 Aug coronal mass ejection.
