**** SPACE WEATHER OUTLOOK ****
Summary For August 21-27
Space weather increased to minor levels. A category R1 (minor) radio
blackout occurred on August 25. Category R1 radio blackouts normally
cause the following system effects on the sunlit side of Earth: minor
degradation of high-frequency radio communication signals resulting in
occasional loss of radio contact for mariners and en route aviators,
and brief degradation of low-frequency navigation signals affecting
maritime and general aviation positioning.
Outlook For August 30-September 5
Space weather is expected to remain at minor levels. There will be a
chance for an isolated category R1 (minor) radio blackout sometime
during the week with effects similar to those mentioned above. There
will also be a chance for a category G1 (minor) geomagnetic storm on
August 30 due to increased solar wind velocities. G1 storms will
typically cause minor impacts on electrical power grids and satellite
operations.
