继10月3日廖家铭发现一颗超新星侯选体之后一天,10月4日,陈剑星,廖家铭,徐佳一在PSP又发现一颗新目标,经孙国佑确认为未知疑似超新星,随后测量上报,报告如下.
POSSIBLE SUPERNOVA IN PGC 4142
Jiaming Liao(Hefei,Anhui,China),Jianxing Chen(Anqing,Anhui,China),Jiayi Xu (Xiaogan,Hubei,China),Guoyou Sun(Wenzhou,Zhejiang,China) and Xing Gao (Urumqi,Xinjiang,China), report the discovery of a possible supernova (mag approximately 16.8) on one 40-s survey image (limiting mag about 19.0) taken by Xing Gao in Xingming Observation Sky Survey(C42) around Oct.03.83492 UT. using an unfiltered CCD ( + Celestron C14 Schmidt-Cassegrain telescope D=356-mm @f/6.9 ). The new object approximately located at R.A.=01h 09m 46s.77 Decl.=+13 18 28.9(equinox 2000.0). Which is about 12.1" east and 3.1" south of the center of the PGC 4142. Nothing is visible at this position on archival images taken on Sept.17(limiting mag 19.0), or on the DSS(POSS-II Red) from Dec.18,1990(limiting mag about 19.5).

星明天文台天阴了半个月,重新开工两天就有两个发现,运气佑人啊。神人廖家铭连续三颗发现,势不可挡。如果都得到光谱验证,将是星明天文台发现超新星总数排第四位的同好。另两位共同发现者陈剑星,徐佳一也又不俗实力,PSP战果喜人~
