这是黑龙江首个超新星发现,也算是国内首个由学生发现的超新星。

以下是CBAT的电报:

SUPERNOVA 2012gq IN PGC 10886 = PSN J02524601+4655523

   Bin Wang, Shaoxing, Zhejiang, China; and Xing Gao, Urumqi, Xinjiang,
China, report the discovery of an apparent supernova (mag approximately 17.7)
on a 40-s unfiltered CCD survey image (limiting mag about 18.5) taken by Xing
Gao in course of the Xingming Observatory Sky Survey using a 0.36-m f/6.9
Celestron C14 Schmidt-Cassegrain telescope at Mt. Nanshan around Nov. 14.667
UT.The new object is approximately located at R.A. = 2h52m46s.01, Decl. =
+46d55'52".3 (equinox 2000.0), which is about 18".3 east and 25".2 south of
the center of PGC 10886.Nothing is visible at this position on archival
images taken on Nov. 2 (limiting mag 18.0), Oct. 26 (limiting mag 18.4), or on
a Digitized Sky Survey image from 1989 Oct. 1 (limiting mag about 19.8).The
discoverer's images are posted at http://www.xjltp.com/XOSS/XM05BW/XM05BW.htm.
The variable was designated PSN J02524601+4655523 when it was posted at the
Central Bureau's TOCP webpage and is here designated SN 2012gq based on the
spectroscopic confirmation reported below.Additional CCD magnitudes for
2012gq (unfiltered unless noted otherwise):Nov. 10.842, 17.6 (Wang and Gao;
prediscovery; position end figures 45s.90, 52".5); 15.422, 18.1 (Joseph
Brimacombe, Cairns, Australia; luminance filter; position end figures 46s.01,
52".5); 17.028, 18.0 (Federica Luppi and Luca Buzzi, Varese, Italy; position
end figures 45s.95, 52".2); 20.923, 17.3 (J. Nicolas, Vallauris, France;
0.41-m f/3.3 reflector; position end figures 45s.96, 52".3).Brimacombe's
image is posted at URL http://www.flickr.com/photos/43846774@N02/8189076189/.
The image of Luppi and Buzzi is posted at the following website URL:

   R. Kotak, T.-W. Chen, and M. Fraser, Queen's University, Belfast, report
that a spectrogram (range 330-975 nm; resolution about 1000) of PSN
J02524601+4655523 = SN 2012gq was obtained on Nov. 21.08 UT with the 4.2-m
William Herschel Telescope (+ ISIS).SN 2012gq has a nearly flat continuum,
with only a slight increase in flux towards the blue.The only evident
feature is broad (around a few thousand km/s) emission at low signal-to-noise,
centered on the rest wavelength of H_alpha in PGC 10886.While the largely
featureless continuum is similar to what is seen in young type-II supernovae,
pre-discovery images constrain 2012gq to be at least 10 days old, while the
slope of the spectrum is also inconsistent with a young supernova.

这是发现时的图片。做反色强化处理。

这是用于发现的设备

SASP(SuperNova and Asteriod search program)是星明天文台的系外超新星、系外新星及主带小行星搜索计划,该项目利用星明远程控制天文台现有设备,对河外星系拍摄巡天,也利用子夜时间对冲日点附近的黄道进行搜索小行星任务。
SASP自2010年10月运行以来,已经发现:

1颗银河系新星
10颗超新星
4颗系外新星
1颗矮新星
70颗小行星



目前服役设备:

赤道仪:Paramount ME

CCD: QHY9

望远镜: Celestron C14(口径356毫米,焦距3916毫米)+F6.9减焦镜

视场:19分(Dec)*25分(RA)

拍摄参数:曝光60秒,FITS格式,BIN=2,像素1792*1284

拍摄极限星等:约19.5等
