**** SPACE WEATHER OUTLOOK ****

Summary For July 29-August 4

Space weather ranged from minor to strong levels. Isolated category R1
(minor) radio blackouts occurred on July 29, 31, and August 2 due to
moderate-sized solar flares. A category R3 (strong) radio blackout
occurred on August 3 at 1:07 p.m. MDT (2002 August 03 1907 UTC) due to
a major solar flare. A category R2 (moderate) radio blackout occurred
on August 4 at 3:55 a.m. MDT (2002 August 04 0955 UTC), also due to a
major solar flare. Category G1(minor) to G2 (moderate) geomagnetic
storm conditions occurred on August 2. Category G1 conditions also
occurred on August 1 and August 3 – 4. The geomagnetic storms were due
to multiple CME passages. There were no solar radiation storms during
the period. For a list of adverse system effects related to space
weather storms, please refer to the NOAA Space Weather Scales.

Outlook For August 7-13

Space weather is expected to decrease to minor levels. Isolated category
R1 (minor) radio blackouts are possible during the period. There is a
slight chance for brief category G1 (minor) geomagnetic storm
conditions during August 7 – 8. No solar radiation storms are
expected.
