9月3日晚,在PSP常规观测过程中,高伟、李言溪、徐智坚、李昂在NGC 6824发现一个非常明亮的超新星候选体,并及时上报TNS。该超新星候选体亮度约14.5等,是本年度全天第二亮度的超新星。

上报文本如下:

POSSIBLE SUPERNOVA IN NGC 6824 Wei Gao, Yanxi Li, Zhijian Xu, Ang Li and Xing Gao report the discovery of a possible supernova in NGC 6824. The transient (mag approximately 14.5) on one 40-s survey image (limiting mag about 19.5) taken by Xing Gao in Xingming Observatory Sky Survey(C42) around Sep. 03.70174, 2017, using a unfiltered CCD ( + Celestron C14 Schmidt-Cassegrain telescope D=356-mm @f/6.9 ). The new object approximately located at R.A.=19h43m40.29s +56d06'36".3 (equinox 2000.0). Which is about 3.2" west and 2.3" north of the center of the NGC 6824.
