标题： Planning Near Earth Asteroid Observations on a 1m Class Telescope

摘要： 已知近地小行星（NEAs）和潜在威胁小行星（PHAs）的数量在过去十年中持续增长。为了改善它们的轨道并预测未来可能与地球相撞的情况，需要对新发现的目标进行后续观测和恢复，以及在第二次或第三次冲日时进行新的天文学测量。提议了一个为期两年的项目，使用1米级望远镜对PHAs和NEAs进行后续观测和恢复。首次观测将在法国Pic du Midi天文台和南非SAAO进行，两者都将使用1米望远镜。未来还寻求其他观测机会。欢迎合作者扩展此项目。 显示英文摘要

摘要： The number of known Near Earth Asteroids (NEAs) and Potentially Hazardous Asteroids (PHAs) has continued to grow in the last decade. Follow-up and recovery of newly discovered objects, as well as new astrometry at second or third oppositions are necessary to improve their orbits and predict any potential collision with the Earth in the future. A project to follow-up and recovery PHAs and NEAs is proposed, using 1m class telescopes in the next two years. Two incoming runs will take place first at Pic du Midi Observatory (France) and SAAO (South Africa), both to use 1m telescopes. Other observing runs are sought in the future. Collaborators to extend this project are welcomed.
