SPACE WEATHER OUTLOOK #01- 45
2001 November 06 at 02:16 p.m. MST (2001 November 06 2116 UT)
**** SPACE WEATHER OUTLOOK ****
Summary For October 29-November 4
Space weather reached category 4 (severe) levels on the NOAA Space
Weather Scales due to a solar radiation storm on November 4. A large
and magnetically complex sunspot group, referred to as Region 9684 by
NOAA space weather forecasters, produced a major flare on November 4 at
4:20 p.m. MST (2001 November 4 1620 UT). This resulted in radio
blackouts reaching category R3 (strong) levels and solar radiation
reaching category S4 (severe) levels on November 4. Earlier in the
summary period, from October 29 – November 3, isolated category R1
(minor) radio blackouts occurred due to moderate-sized solar flares.
On November 1 a category G1 (minor) geomagnetic storm occurred as a
weak CME (coronal mass ejection) passed earth. For a list of adverse
system effects related to space weather storms, please refer to the
NOAA Space Weather Scales.
Outlook For November 7-13
Space weather is expected to range from minor to moderate levels.
Category R1 (minor) to R2 (moderate) radio blackouts are possible
during the period. There will be a continuing category S2 (moderate)
solar radiation storm on November 7 which should subside to a category
S1 (minor) storm and end by November 8 or November 9. A category G1
(minor) geomagnetic storm is possible on November 7 due to the effects
of a CME passing earth on November 6.
