摘要
本文给出北京天文台2.16m望远镜SN1993J光谱观测结果.
Continuous spectrascqpic observations of SN1993J have been conducted in Beijing Observatory's 2. 16 meter telescope. We discuss in this letter the data obtained from April 7 to May 5, 1993. Investigations of the time evolution of the various absorption and emission lines show that the supernova debris is not spherically symmetric. Possible structures are discussed.
