**** SPACE WEATHER OUTLOOK ****

Summary For October 16-22

Space weather reached minor levels during the week. Isolated category R1
(minor) radio blackouts occurred on October 16 and 21. These blackouts
likely caused occasional loss of high-frequency radio contact and brief
degradation of low-frequency navigation signals, with effects limited
to the sunlit side of Earth. A category S1 (minor) solar radiation
storm occurred during October 16 – 17. Category S1 radiation storms
typically result in minor impacts on high-frequency radio communication
in the polar regions.

Outlook For October 25-31

Space weather is expected to remain at minor levels. Isolated category
R1 (minor) radio blackouts are possible during the period with effects
similar to those mentioned above.
