**** SPACE WEATHER OUTLOOK ****

Summary For August 26-September 1
Space weather reached strong levels. A category R3 (strong) radio
blackout occurred due to an energetic solar flare that erupted at 7:29
a.m. MDT (mountain daylight time) on August 30th. Category R1 (minor)
radio blackouts also occurred on August 26, 28 and 29th. The
geomagnetic field surrounding earth had a category G1 (minor) storm
on August 26th due mainly to a cloud of solar material interacting with
Earth’s magnetic field. For a list of adverse system effects due to
space weather storms, please refer to the NOAA Space Weather Scales.

Outlook For September 4-10
Space weather is expected to reach the minor levels. Category R1
(minor) radio blackouts are possible. There is a slight chance of a
category R2 (moderate) radio blackout occurring after September 7th.
