2月21日至3月1日,PSP系统连续发现4颗超新星候选体,呈井喷态势。
按照正常情况,目前的观测设备系统,平均每年发现10颗超新星,而且随着国际竞争愈发激烈,发现会越来越困难。
然而随着PSP系统的逐步成熟,目前这种全新的看图搜索模式体现出了极强的优势和效率,自2016年新年以来已经先后发现7颗超新星侯选体以及确认一颗系外新星,也就是说一个季度干了一年的活,可谓战果喜人。尤其是最近三颗候选体,按照以前的看图模式基本是无力发现的,这体现了PSP系统的优越性。
随着PSP系统的逐步稳定以及其在天文爱好者群体的影响力逐步提高,发现超新星已经基本走向常态,去年廖家铭小朋友的发现导致的新闻效应冲击已经趋于平静,我相信这是一个系统走向成熟的标志,也体现了当初PSP项目建立的初衷,是其在天文科普工作方面的一种全新的更具有生命力的工作模式。科普既要有新闻媒体的大力宣传,自身也要有足够的“干货”,否则也只能是昙花一现,吸引眼球而已。
自PSP项目于2015年7月29日上线以来,已经有6500名以上的同好参与搜索,PSP官方网站已经有超过1.5万人注册。目前通过PSP系统发现超新星的人数已经近40人,其中年龄跨度10至54岁,各行各业的参与者都有。

POSSIBLE SUPERNOVA IN AN ANONYMOUSE GALAXY
Yi Ding, Wei Gao and Xing Gao,report the discovery of a possible supernova(mag approximately 15.7)on one 40-s survey image(limiting mag about 19.0)taken by Xing Gao in Xingming Observation Sky Survey(C42)around Feb.20.99075 UT. Using an unfiltered CCD( + Celestron C14 Schmidt-Cassegrain telescope D=356-mm @f/6.9). The new object approximately located at R.A.=18h 44m 12s.49 Decl.=+24 09 29.7(equinox 2000.0), which was found in an anonymous galaxy near PGC 62338. Nothing is visible at this position on archival images taken on Nov.13,2015(limiting mag 19.0), or on the DSS (POSS-II Red) from Jun.20,1992 (limiting mag about 19.5).

The new object approximately located at R.A.=10h 55m 53s.83 Decl.=+36 51 48.0(equinox 2000.0). Nothing is visible at this position on archival images taken on Feb.26(limiting mag 19.0), or on the DSS(POSS-II Red) from May.15,1985(limiting mag about 20.5).
