摘要

本文报道了2017年6月6夜对SU UMa矮新星NY Her的CDD光度测量结果。光曲线在0m.7 ~ 1m.1范围内明显表现出强烈的振幅变化。时间序列分析显示了0.07141(5)d的周期，我们认为这是NY Her可能的阴性超峰期。

NY Her: possible discovery of negative superhumps

We presents result of CDD photometry for SU UMa dwarf nova NY Her during 6 nights in June 2017 when object was in quiescence. Light curves clearly show strong amplitude variations in a range of 0m.7-1m.1. Time series analysis revealed a period 0.07141(5) d, that we identified as the period of possible negative superhumps of NY Her.
