金彰伟 XM22ZJ = POSSIBLE SUPERNOVA IN PGC32321 ? 超新星

6月28日晨,金彰伟和孙国佑一起分工合作,以求尽快把星系图片检查完毕。金彰伟很快在第一区域中的星系PGC32321处发现可能有超新星爆发,排除各种可能性后把高兴从睡梦中叫醒,由高兴上报相关数据。第二晚,意大利人确认了我们的发现。
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).
