SPACE WEATHER ADVISORY OUTLOOK #03- 21
2003 May 27 at 11:32 a.m. MDT (2003 May 27 1732 UTC)

**** SPACE WEATHER OUTLOOK ****

Summary For May 19-25
Space weather reached minor levels last week. A category G1 (minor)
geomagnetic storm began late on May 21st and lasted through May 25th.
The source of the storm was a coronal hole on the sun with high speed
solar winds. Geomagnetic storming occurs when the high speed solar
wind interacts with the Earths magnetic field. For a list of adverse
system effects related to space weather storms, please refer to the
NOAA Space Weather Scales.

Outlook For May 28-June 3
Space weather for the next week is expected to be at minor levels.
Category G1 geomagnetic storms are expected early in the week due to
another coronal hole rotating into a favorable position for interacting
with Earth. Category R1 (minor) radio blackouts are possible early in
the week due to an active sunspot region on the sun.
