GALILEO PWS CALLISTO 9 OBSERVATION PLANNING


What's new (14 December 1995)

An overview of the C9 encounter period

Orbit geometry

And 1-day summaries for greater detail:

Magnetospheric Survey, R > 50 Rj

Spectrum Analyzer Mode:

Wideband Mode: (This is mostly irrelevant since little or no wideband data will be obtained in the Magnetospheric Survey--only occasional fill data)


Magnetospheric Survey, R < 50 Rj

Encounter Geometry

Spectrum Analyzer Mode:

Wideband Mode: (This is mostly irrelevant since little or no wideband data will be obtained in the Survey--only occasional fill data and data which is automatically recorded with remote sensing recorded observations)


Callisto Closest Approach

Closest approach geometry and

Flux tube crossing geometry
