摘要
我们呈现对1RXS J165424.6-433758的X射线、紫外与光学后续观测活动结果，该X射线源由\textit{Swift}深银道面巡天（DGPS）探测到。其X射线能谱（\textit{Swift}与\textit{NuSTAR}）由温度 keV的热轫致辐射描述，在\textit{Gaia}距离460 pc处给出X射线（ keV）光度 erg s。南非大望远镜（SALT）光谱揭示由发射线主导的平坦连续谱，表现出反巴耳末减缩、鲍恩混合、近十二条约HeI线，以及HeII 、与。我们的高速测光显示大量闪变与耀发事件，并揭示系统轨道周期 hr，恰落于激变变星（CV）2-3 hr的周期间隙内。这些特征将1RXS J165424.6-433758分类为邻近的极向磁CV。
