POSSIBLE SUPERNOVA IN PGC 10886
Bin Wang(Shaoxing, Zhejiang, China) and Xing Gao
(Urumqi,Xinjiang,China), report the discovery of a possible supernova
(mag approximately 17.7) on a 40-s survey image (limiting mag about
18.5)taken by Xing Gao in Xingming ObservationSky Survey(C42) around
Nov. 14.66703 UT. using an unfiltered CCD ( + Celestron C14
Schmidt-Cassegrain telescope D=350-mm @f/6.9 ). The new object
approximately located at R.A. =02h 52m 46s.01
Decl.=+46o55’52”.3(equinox 2000.0). Which is about 18.3″ east and
25.2″ south of the center of the PGC 10886. Nothing is visible at this
position on archival images taken on Nov. 02(limiting mag 18.0), Oct.
26(limiting mag 18.4) or on the DSS from Oct. 01,1989(limiting mag
about 19.8).
