Reconstruction of the
Solar/Interplanetary Disturbances for the Space Weather Event on
6-10 Jan 1997
The filament disruption
was recorded in
ultraviolet light at an Air
Force Observatory
(SOON) site. The
Yohkoh soft x-ray
telescope recorded
some
brightening/changing of
x-ray emitting loops
overlying the same
magnetic field region on
6-7 Jan. This feature is
the likely source of
a weak, long duration
x-ray event detected on
the GOES spacecraft.
Long duration x-ray
events are another
well-known proxy for
CME occurrence. (Both
figures are from the ISTP
events web site at NASA
GSFC. Yohkoh is a joint
ISAS/NASA mission with
an open data set policy.)

The extent to which the
filament disruption, and
coronal loops, are
associated with changes
in the photospheric field
are testable using MDI
observations of the
evolving southern active
region as boundary
conditions in the NRL
3-D MHD mesoscale
model. (The figure shows
field lines (blue), and the
associated prominence
(red) from the NRL model
applied to a hypothetical
event.) Click on the image
