摘要
我们报告对 HSC16aayt (SN 2016jiu) 的观测，该源由作为 Subaru 战略计划 (SSP) 一部分的 Subaru/超广角主焦点相机 (HSC) 暂现源巡天发现。它表现出非常缓慢的光度演化，其上升时间超过100天。在400天内其光学星等变化保持在0.6 mag以内。HSC16aayt 的光谱显示强窄发射线，我们将其分类为 IIn 型超新星。根据光谱得出 HSC16aayt 的红移为 0.6814 ± 0.0002。其宿主星系中心距超新星位置 5 kpc，HSC16aayt 可能是孤立 IIn 型超新星的又一例，尽管不排除超新星位置处宿主星系存在潜在恒星形成活动的可能性。
