SPACE WEATHER ADVISORY OUTLOOK #03- 43
2003 October 28 at 04:11 p.m. MST (2003 October 28 2311 UTC)
**** SPACE WEATHER OUTLOOK ****
Summary For October 20-26
Space weather during the past week reached strong levels. Category R3
(strong) radio blackouts occurred on October 23rd and again on October
26th due to solar flares from three large dynamic sunspot regions on
the sun. A major flare occurred at 1:35 A.M MDT (0835UTC) on October
23rd producing a category R3 (strong) radio blackout and on October
24th a brief category G3 (strong) geomagnetic storm. Another major
flare occurred at 12:19 P.M. MST (1819UTC) on October 26th and produced
an associated category S2 (moderate) solar radiation storm at 12:25
P.M. MST (1825Z). The three dynamic sunspot regions continued to
produce significant flares throughout the week, resulting in category
R1 - R2 radio blackouts on October 20th to 23rd and again on October
24th, and 25th. For a list of adverse system effects related to space
weather storms, please refer to the NOAA Space Weather Scales.
At the time of this report issue a category R4 (Severe) radio blackout
occurred at 5:10 A.M. MST (1110 UTC) on October 28th due to a major
solar flare. This flare also produced a category S3 (strong) solar
radiation storm.
Outlook For October 29-November 4
Space weather for the next week is expected to reach extreme levels. A
category G5 (extreme) geomagnetic storm is expected late on day one or
early on day two of the forecast period. The category S3 solar
radiation storm that started today is expected to continue for the next
two days and may reache category S4 (severe) levels. The dynamic
sunspot regions currently on the sun are expected to be active
throughout the week and may produced a category R1 (minor) to R3
(strong) radio blackout. Solar radiation storms are also possible from
these sunspot regions.
