SPACE WEATHER ADVISORY OUTLOOK #02- 53
2002 December 31 at 12:35 p.m. MST (2002 December 31 1935 UTC)
**** SPACE WEATHER OUTLOOK ****
Summary For December 23-29
Space weather reached moderate levels during the last week. Category G1
(minor) and G2 (moderate) geomagnetic storm periods occurred on
December 27th, due to effects from high velocity solar wind from a
coronal hole on the sun. A category G1 (minor) geomagnetic storm
period occurred on December 23rd, due to transient effects from a
period of sustained southward orientation in the interplanetary
magnetic field, accompanied by high velocity solar wind. For a list of
adverse system effects related to space weather storms, please refer to
the NOAA Space Weather Scales.
Outlook For January 1-7
Space weather is expected to be at minor to moderate levels. Category
G1 (minor) to G2 (moderate) geomagnetic storm periods may occur on
January 4th, 15th-16th, and 22nd-24th, due to expected effects from
coronal hole features that rotate with the sun and will pass through
earth-directed sectors on those dates. A chance for isolated Category
R1 (minor) radio blackouts may accompany the expected return of
flare-producing sunspot regions to the visible side of the sun during
the period of January 4th through 23rd.
