Ziheng Zhang,Cheng Ji,Jiangao Ruan and Xing Gao, report the discovery of
a possible supernova (mag approximately 18.0) on one 40-s survey image (limiting
mag about 19.0) taken by Xing Gao in Xingming Observation Sky Survey (C42)
around Mar.01.64185 UT. Using an unfiltered CCD ( + Celestron C14 Schmidt-Cassegrain
telescope D=356-mm @f/6.9). The new object approximately located at R.A.=08h
33m 41s.05 Decl.=+41 25 08.6 (equinox 2000.0). Which is about 10.4" west
and 6.2" south of the center of the PGC 24017.
Nothing is visible at this position on archival images taken on Feb.03,2016 (limiting mag 19.0), or on the DSS (POSS-II Blue) from Apr.08,1997 (limiting mag about 19.5).
