**** SPACE WEATHER OUTLOOK ****

Summary For April 24-30 Space weather was relatively calm. There were no storms detected during the period.

Outlook For May 3-9 Isolated (minor) R1 radio blackouts may occur sometime during the period. Should an R1 radio
blackout occur, expect the following effects on the sunlit side of Earth: minor degradation of high-frequency
communication signals resulting in occasional loss of radio contact for mariners and en route aviators, and minor
degradation of low-frequency navigation signals for brief intervals affecting maritime and general aviation positioning.
No solar radiation storms are expected. No geomagnetic storms are expected, barring an Earth-directed coronal mass
ejection (CME).
