SPACE WEATHER ADVISORY OUTLOOK #03- 49
2003 December 09 at 03:48 p.m. MST (2003 December 09 2248 UTC)

**** SPACE WEATHER OUTLOOK ****

Summary For December 1-7
Space weather during the past week reached moderate levels. Category R1
(minor) radio blackouts were observed on the 2nd and 6th of December.
These blackouts were associated with eruptions that occurred in an
active region near the SW limb of the sun. Periods of G1 (minor) and
G2 (moderate) geomagnetic storming were observed on 5 December. This
storming was due to the combined effects of a high speed solar wind
flow from a coronal hole on the sun, and a glancing blow from a coronal
mass ejection that occurred on 2 December. For a list of adverse
system effects related to space weather storms, please refer to the
NOAA Space Weather Scales.

Outlook For December 10-16
Space weather for the next week is expected to reach moderate levels. A
category G2 geomagnetic storm is expected during the first half of the
week due to high speed solar wind from a large, favorably positioned
coronal hole on the sun. The geomagnetic storm is expected to end by
14 December. R1 radio blackouts are possible late in the week when
active regions are expected to rotate onto the visible disk.
