SPACE WEATHER OUTLOOK #00- 15
2000 April 04 at 01:30 p.m. MDT (2000 April 04 1930 UT)
Summary For March 27-April 2 Occasional category R1 (minor) radio blackouts occurred during the week due
to solar flares. R1 radio blackouts typically manifest themselves as minor degradation of high-frequency radio
communication signals on the sunlit side of Earth resulting in occasional loss of radio contact for mariners and
en route aviators. Low-frequency navigation signals are also degraded for brief intervals on the sunlit side of
Earth as a result of R1 radio blackouts, which affect maritime and general aviation positioning.
Outlook For April 5-11 Occasional R1 radio blackouts are expected. An isolated R2 (moderate) radio blackout
is possible sometime during the period.
