Drs. Burton Jones, Arnold Klemola, and Robert Hanson at the Lick Observatory, University of California, Santa Cruz will continue work on the Lick Northern Proper Motion program. Observations for a major phase of the second epoch in this program are nearly complete, and the emphasis for the next two years will be on plate measurements and the preparation of a machine readable form of the survey. The study of the motions of various classes of stars is fundamental to an understanding of our Galaxy. Proper motions provide the observational basis for the study of solar motion, galactic rotation, and velocity dispersions, and for the statistical determination of stellar distances and luminosities. The Lick Northern Proper Motion program will meet many of these basic observational needs by providing absolute proper motions for some 300,000 stars covering the northern two-thirds of the sky.

博士。伯顿·琼斯（Burton Jones），阿诺德·克雷莫拉（Arnold Klemola）和加利福尼亚大学圣克鲁斯分校的莱克天文台的罗伯特·汉森（Robert Hanson）将继续从事Lick Northern适当的运动计划。 该程序中第二个时期的主要阶段的观察几乎是完整的，接下来的两年的重点将是板测量和准备机器可读形式的调查形式。 对各种恒星的运动的研究是对我们银河系的理解至关重要的。 适当的运动为研究太阳运动，银河旋转和速度分散体以及恒星距离和亮度的统计确定提供了观察基础。 Lick Northern适当的运动计划将通过为覆盖北部三分之二天空的约300,000颗恒星提供绝对适当的动作来满足许多基本的观察需求。
