Subj:   I27 EUV torus MBTG

Hi Duane,

The EUV torus observation in I27 has the science objective of obtaining the
only ansa-to-ansa dusk torus observation of either the GEM or the prime
mission. There have been asymmetries hinted at between the energy output in
the EUV for the dusk and dawn, noon and midnight sectors of the torus but
neither the quantitative description nor the interpretation of these
asymmetries has been adequately addressed. This observation in I27 will
provide that comprehensive dataset for comparison to prime mission dawn
torus data and to E26 dusk midnight ansa data. E26 and I27 datasets will
complement one another well in that time variations can be averaged to
provide a general dusk torus characterization for the midnight ansa. The
total MBTG needed for the EUV Io torus observation is 1.35 MBTG in I27.
