9400168 Michael F. A'Hearn Dr. A'Hearn and his colleagues plan to expand their normal observational program on comets and asteroids in order to carry out an extensive effort for Comet Shoemaker-Levy 9 and its impact onto Jupiter. They are emphasizing the study of the dust grains in the coma and tail, which together are a system much larger than the entire Jovian system. Observations will be conducted during the spring of 1994 to elucidate the properties of the grains. The investigators will then carry out a program of coronagraphic imaging and spectroscopy during the several weeks surrounding the period when the major fragments will impact the planet. This will be aimed at determining the interaction of the grains (and any gas) with the magnetosphere and ring and torus of Jupiter.

9400168 Michael F. A'Hearn A'Hearn 博士和他的同事计划扩大他们对彗星和小行星的正常观测计划，以便为舒梅克-利维 9 号彗星及其对木星的影响开展广泛的工作。 他们强调对彗发和尾部尘埃颗粒的研究，这两个系统加在一起是一个比整个木星系统大得多的系统。 将于 1994 年春季进行观察，以阐明这些谷物的特性。 然后，研究人员将在主要碎片撞击地球期间的几周内执行日冕成像和光谱学计划。 其目的是确定颗粒（以及任何气体）与木星磁层、环和环面的相互作用。
