SPACE WEATHER ADVISORY OUTLOOK #03- 20
2003 May 13 at 10:06 a.m. MDT (2003 May 13 1606 UTC)

**** SPACE WEATHER OUTLOOK ****

Summary For May 5-11
Space weather has reached moderate levels. The geomagnetic field has
been at storm levels for much of the week. Activity reached category
G2 (moderate) levels on May 7th, May 10th and May 11th. Category G1
(minor) storm levels were observed on May 6th, May 8th, and May 9th.
The long duration geomagnetic storm is due to a very large coronal hole
on the sun, which is producing sustained high speed solar winds. Often
times geomagnetic storming results when these high speed solar winds
interact with 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 14-20
Space weather is expected to be at minor to moderate levels. The
geomagnetic storm currently in progress is expected to continue at
category G1 and G2 levels.
