POSSIBLE SUPERNOVA IN PGC 32321
Zhangwei Jin(Ningbo, Zhejiang, China) and Xing Gao (Urumqi, Xinjiang, China), report the discovery of a possible supernova (mag approximately 17.1) on a 60-s survey image (limiting mag about 19.5)taken by Xing Gao in Xingming ObservationSky Survey(C42) around Jun. 27.69590 UT,2011. using a unfilled CCD ( + Celestron C14 Schmidt-Cassegrain telescope D=350-mm @f/6.9 ).the new object approximately located at R.A. =10h 48m 37.82 Decl.=+66°21’36”.3 (equinox 2000.0). Which is about 15.6″ west and 8.4″ north of the center of the PGC 32321.
Nothing is visible at this position on archival images taken on May. 16 (limiting mag 18.5) or on the DSS(POSS2/UKSTU Red) from Feb 08,1997 (limiting mag about 19.5).NET USNO-A2.0
