Nj. Fox et al., CRADLE TO GRAVE TRACKING OF THE JANUARY 6-11, 1997 SUN-EARTH CONNECTION EVENT, Geophysical research letters, 25(14), 1998, pp. 2461-2464
During the interval January 6-11, 1997, the satellites and ground faci
lities of the International Solar-Terrestrial Physics (ISTP) ''Observa
tory'' tracked a solar eruption from the Sun to the Earth. The resulti
ng Coronal Mass Ejection (CME) took four days to travel through interp
lanetary space before arriving at Earth, where it caused electromagnet
ic disturbances and spectacular aurorae. The initial expulsion lifted
off the Sun on January 6, the resulting magnetic cloud arrived on Janu
ary 10, and its effects lasted over 24 hours. The initial solar observ
ations from SOHO were reported on January 7, during an ISTP Science Wo
rkshop on Sun-Earth Connection events. This alerted the community to t
he impending arrival of the CME thereby allowing the event to be monit
ored in 'real-time' using the wide variety of ISTP instruments. This e
vent provided the first ever end to end tracking of a space storm. Fur
ther, it provided a strong pressure pulse of extremely high density re
sulting in the compression of the magnetopause to within geosynchronou
s orbit during northward IMF conditions. Here we present an overview o
f the event and available observations.
