SPACE WEATHER ADVISORY OUTLOOK #03- 10
2003 March 11 at 11:32 a.m. MST (2003 March 11 1832 UTC)
**** SPACE WEATHER OUTLOOK ****
Summary For March 3-9
There has been no significant space weather during the past week. Two
category G1 (minor) geomagnetic storms occurred during the past week.
The first one occurred on March 4th due to a high speed solar wind
stream. High speed solar wind streams are commonly associated with
coronal holes on the sun. A second G1 storm occurred on March 6th as a
result of a second coronal hole with an associated high speed solar
wind stream. When a high speed stream of solar wind interacts with the
Earths magnetic field geomagnetic storming can occur. For a list of
adverse system effects related to space weather storms, please refer to
the NOAA Space Weather Scales.
Outlook For March 12-18
There is a slight chance of a category R1 (minor) radio blackout due to
an active sunspot region. A category G1 (minor) geomagnetic storm is
possible late in the week, around March 15th, due to a large coronal
hole rotating onto the visible side of the sun. This coronal hole is
expected to have a high speed solar wind stream associated with it.
