95-31586 A'Hearn Dr. A'Hearn and his Co-Principal Investigator, Dr. Timothy A. Livengood, will carry out ground-based thermal infrared (IR) observations of Jupiter and its environment, supporting and complementing an international ultraviolet (UV) observing program. Dr. Livengood is one of the two principal investigators of the international UV observing program. Both the IR and UV efforts will run in parallel with and complement the observations of Jupiter by NASA's Galileo mission, which is presently orbiting the planet and obtaining data. The ground-based thermal IR observations will be carried out with the thermal-infrared imaging camera at the European Southern Observatory. The wavelengths of the observations are chosen to coincide with emissions from a range of hydrocarbons. The objective is to understand better the auroral activity in the Jovian System, the transfer of material from Jupiter's satellite Io to the plasma torus surrounding Jupiter, energization of the torus plasma, seasonal response and photochemistry in the planet's stratosphere, and energization of day glow emission. ***

95-31586阿赫恩博士和他的联合首席研究员蒂莫西·利文古德博士将对木星及其环境进行地面热红外(IR)观测，支持和补充一项国际紫外线(UV)观测计划。利文古德博士是国际紫外线观测计划的两位主要研究员之一。红外和紫外光的工作将与NASA的伽利略任务对木星的观测平行进行，并与之相辅相成。伽利略任务目前正在绕木星轨道运行并获取数据。地面热红外观测将使用欧洲南方天文台的热红外成像仪进行。观测的波长被选择为与一系列碳氢化合物的排放相一致。其目的是更好地了解木星系统中的极光活动，木星卫星木卫一向木星周围等离子体环的物质转移，环等离子体的能量，行星平流层中的季节反应和光化学，以及白天发光的能量发射。***
