GALILEO UVS/EUV ATMOSPHERIC AND AURORAL OBSERVATIONS PRIME MISSION ORBITS G1 - E11 I. UVS AWG OBSERVATIONS The Galileo ultraviolet spectrometer (UVS) instrument observes both atmospher- ic and auroral features during periods that are coincident with other observ- ing programs such as the HST cycles 5, 6, and 7. The UVS instrument makes in- dependent sets of observations as part of and separate from the Galileo Atmo- spheric Working Group (AWG) feature track campaign periods. Both types of ob- servations are listed below (UVS calibrations are not included in this list- ing). The general characteristics of the UVS instrument are the following: G channel = 113.3-192.1 nm 2nd order; 0.67 nm resolution; FOV = 0.1x1.0 deg F channel = 162.0-323.1 nm 1st order; 1.36 nm resolution; FOV = 0.1x0.4 deg N channel = 282.0-432.0 nm 1st order; 1.27 nm resolution; FOV = 0.1x1.0 deg The Galileo extreme ultraviolet (EUV) instrument, in addition to its Io torus observations, also views the Jupiter aurora. Its coincident observations with the UVS are noted in the comments below. II. UVS AWG SCIENCE OBJECTIVES - KEY QUESTIONS STRATOSPHERIC AEROSOLS AND HYDROCARBONS: * What are the vertical and horizontal distributions of stratospheric aerosols and hydrocarbons (e.g., acetylene)? * What are the characteristics of stratospheric circulation? * How do unique atmospheric features compare with one another (e.g., GRS, belts/zones, white ovals, 5 micron hot spots, "barges", polar hazes)? AURORAE: * What is the global energy output? * What are the spatial (vertical and System III) and temporal (minutes to months) characteristics? * What are the spectral characteristics in the EUV, FUV, MUV, and NUV? * What is the auroral region atmospheric composition? * How are the atmosphere and magnetosphere coupled? AIRGLOW: * What are the spatial (System III), spectral, and energy characteristics of the thermospheric hydrogen? * What is the H limb brightening function? * What are the characteristics of the hydrogen corona?

UVS AWG OBSERVATIONAL RESULTS (as of update at the end of this document) [NOTE: the spatial resolution varies with SYSTEM III (lat/lon) and HEMISPHERE (north-south/day-night) while the temporal resolution varies from SHORT-TERM (hours) to LONG-TERM (weeks).] STRATOSPHERIC AEROSOLS and HYDROCARBONS Feature tracks: Great Red Spot & vortices G1, C9 Acetylene distribution G2 belt-zone boundary C3 5 micron hot spot E4 white oval E6 brown barge G7 southern polar haze G8 plume C9 hi phase crescent C9 AURORAE EUV G1, C3, E4, E6, G7 (G) FUV G1, G2, C3, E4, E6, G7, G8, C9 (F) MUV G1, C3, E4, E6, G7, C9 (N) NUV (none) IMAGE/SPECTRA C3, G7, C9 AIRGLOW Lyman-alpha distribution G1, G2, C3, E4, E6, G7, G8, C9 Lyman-alpha limb curve G1, G2, G8 EUV H2 dayglow J0CD, G2, C3 FUV H2 dayglow G2, E4, E6, G7, G8 Hydrogen corona G8 IV. UVS AWG ORBIT PLANNING The following table describes the Galileo orbit, observed or planned UVS ob- servation name, UTC start time of the observation, end time, FOV center lati- tude/longitude (System III), and brief science objective. The Galileo orbit nomenclature uses a 3-character designator and is listed in the table under the header title "Orbit". The first letter indicates the encounter body ("J" = Jupiter, "G" = Ganymede, "C" = Callisto, and "E" = Europa); the second number indicates the actual orbit (beginning with the Jupiter approach orbit = "0"); the third letter designates the Galileo CDS (on-board computer) memory load sequence (useful primarily for Galileo archive purposes). As an example, "J0E" = Jupiter encounter, orbit 0, "E" sequence load; "G1A" = Ganymede encounter, orbit 1, "A" sequence load. The Galileo observation names are constructed using most of the information above (excluding the memory load sequence identifier) with the nomenclature: <6 character observation mnemonic> For example, "G1JUEWMAPS01" = Orbit G1, Jupiter target body, UVS instrument, East-West MAPS, observation sequence number 01. Many of the auroral observa- tions and feature tracks are conducted as campaigns with ground (e.g. IRTF), HST, and Galileo F&P instruments.
