POSSIBLE SUPERNOVA IN IC 1267
Ang Li, Xu Guo, Cheng Ji, Peiyuan Sun and Xing Gao, report the discovery of a possible supernova (mag approximately 17.1) on one 40-s survey image (limiting mag about 19.0) taken by Xing Gao in Xingming Observation Sky Survey (C42) around Feb.06.96678 UT. Using an unfiltered CCD ( + Celestron C14 Schmidt-Cassegrain telescope D=356-mm @f/6.9). The new object approximately located at R.A.=17h 38m 46s.61 Decl.=+59 22 22.4(equinox 2000.0). Which is about 0.7″ east and 0.9″ south of the center of the IC 1267.
Nothing is visible at this position on archival images taken on May.27,2015 (limiting mag 19.0), or on the DSS (POSS-II IR) from Jun.19,1992 (limiting mag about 19.0).
Bin Tian’s private observatory follow-up the possible supernova (mag approximately 16.5) on one 300-s image (limiting mag about 18.0) around Feb.08.83472 UT. Using a CCD + Sharpstar AL-130 Refracting telescope D=130-mm @f/6.67.
