SPACE WEATHER ADVISORY OUTLOOK #03- 19
2003 May 06 at 01:20 p.m. MDT (2003 May 06 1920 UTC)

**** SPACE WEATHER OUTLOOK ****

Summary For April 28-May 4
Space weather has reached moderate levels. A geomagnetic storm occurred
during the past week and reached category G1 (minor) levels on April
29th, category G2 (moderate) on April 30th through May 1st, and
returned to G1 levels on May 2nd. This geomagnetic storm was due to
high speed solar wind from a coronal hole on the sun and its
interaction with Earth's magnetic field. A category R1 (minor) radio
blackout occurred on April 28th at 9:59 P.M. MDT (May 29th, 0459 UTC)
due to an energetic solar flare. A second category R1 radio blackout
occurred on May 1st at 8:08 P.M. MDT (May 2nd, 0308 UTC). A very
large sunspot region known to NOAA space weather forecasters as Active
Region 349 was visible on the sun during the week. For a list of
adverse system effects related to space weather storms, please refer to
the NOAA Space Weather Scales.

Outlook For May 7-13
Space weather is expected to be at minor to moderate levels. Another
large coronal hole with associated high speed solar wind is expected to
cause category G1 geomagnetic storming early in the week. There is a
chance that storming may reach the G2 level. Late in the week a
previous active region is due to rotate onto the visible side of the
sun and may produce isolated category R1 radio blackouts.
