**** SPACE WEATHER OUTLOOK ****
Summary For September 16-22
Space weather reached minor levels during the period. Three
short-lived, category R1 (minor) radio blackouts affected Earthís
ionosphere due to solar flare activity from sunspots. These radio
blackouts peaked at the following times: 9:10 p.m. MDT (mountain
daylight time) on September 16th, 11:12 p.m. MDT on September 19th, and
3:28 a.m. MDT on September 20th.
Outlook For September 25-October 1
Space weather may reach minor levels, as a slight chance for additional
category R1 (minor) radio blackouts is possible in response to expected
sunspot activity during the forecast period.
