ABSTRACT
Many problems of current interest in the solar system
require simultaneous observations of time­variable
phenomena at multiple wavelengths. This is true,
for example, of studies that involve the excitation
of molecules, which are excited through electronic
transitions in the ultraviolet and through rotational
and vibrational transitions in the infrared and mil­
limeter regimes. It is also true for the study of
plasma processes in which direct detection of elec­
tron impact processes requires observations in the ul­
traviolet, while the ultimate result is heating which
shows up in the excitation measured at infrared wave­
lengths. Other such problems involve determing the
