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. Observatios for the second epoch in this program are nearly complete, and the emphasis will shift toward plate surveys and measurements over the next three years. 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.

伯顿·琼斯博士，阿诺德·克莱莫拉和罗伯特·汉森在舔 天文台，加州大学，圣克鲁斯将继续 研究“舔北方自行”项目 观察结果 这个计划的第二个时期已经接近完成， 重点将转向板块调查和测量， 未来三年 对各类恒星运动的研究 对了解银河系至关重要 自行运动 为研究太阳运动提供了观测依据， 银河系的旋转和速度分散， 恒星距离和光度的统计测定。 “舔北方自行车”计划将满足许多这些要求， 提供绝对自行的基本观测需要 大约有30万颗恒星覆盖了银河系北方的三分之二， 天空
