Sa. Stern et al., ROCKET FUV OBSERVATIONS OF THE IO PLASMA TORUS DURING THE SHOEMAKER-LEVY 9 IMPACTS/, Geophysical research letters, 22(13), 1995, pp. 1837-1840
We observed the Io torus from 820-1140 Angstrom on UT 20.25 July 1994
from a sounding rocket telescope/spectrograph. These observations serv
e as only the fourth published spectrum of the torus in this wavelengt
h range, and the only FUV data documenting the state of the torus duri
ng the Shoemaker-Levy 9 impacts.
