Official Space Weather Advisory issued by NOAA Space Environment Center
Boulder, Colorado, USA

2002 December 24 at 12:05 p.m. MST (2002 December 24 1905 UTC)


Summary For December 16-22
Space weather reached moderate levels during the past week. A category
R2 (moderate) radio blackout occurred due to an energetic solar flare
on December 20th at 6:18 A.M. MST (1318 UTC). Category R1 (minor)
radio blackouts occurred on December 16-19th and on December 22nd. A
category G1 (minor) geomagnetic storm occurred on December 19th due to
high solar wind speed from a coronal hole on the sun. For a list of
adverse system effects related to space weather storms, please refer to
the NOAA Space Weather Scales.

Outlook For December 25-31
Space weather is expected to be at minor levels. Isolated Category R1
(minor) radio blackouts are possible during the week. A number of
flare producing sunspot regions are due to rotate to the far side of
the sun by December 28th. This is expected to result in fewer radio
blackouts during the next week.
