POSSIBLE SUPERNOVA IN NGC 5430
Guoyou Sun(Wenzhou, Zhejiang, China) and Xing Gao (Urumqi, Xinjiang,
China)，report the discovery of a possible supernova (mag approximately 17.2)
on several 60-s survey images (limiting mag about 19.5)taken by Xing Gao in
Xingming Observation Sky Survey(C42) around Oct. 3.60524 UT using a unfilled
CCD Camera ( + Celestron C14 Schmidt-Cassegrain telescope D=350-mm @f/6.9 ).
the new object approximately located at R.A. =14h 00m 47s.14
Dec:=+59°20’16”.8 (equinox 2000.0). Nothing was visible at this position on
DSS on Apr 8,1997(limiting mag about 19.5).

POSSIBLE SUPERNOVA IN NGC 5430
Guoyou Sun, Wenzhou, Zhejiang, China; and Xing Gao, Urumqi, Xinjiang,
China, report the discovery of a possible supernova (mag approximately 17.2)
on 60-s survey images (limiting mag about 19) taken by Xing Gao in the
course of the Xingming Observation Sky Survey at Mt. Nanshan around Oct. 3.605
UT using an unfiltered CCD camera with a Celestron C14 Schmidt-Cassegrain
telescope. The new object is located at R.A. = 14h00m47s.12 +/- 0s.12, Decl.
= +59d20’17”.0 +/- 0″.2 (equinox 2000.0; measured by Sun), which is 13″.7
west and 33″.5 north of the nucleus of NGC 5430. Nothing is visible at this
position on a Digitized Sky Survey image from 1997 Apr. 8 (limiting mag about
19.5; no bandpass stated). Additional magnitudes for the variable provided
by Sun: Oct. 4.578, 17.2; 5.588, 16.9; 6.584, 16.7.
Following posting on the Central Bureau’s unconfirmed-objects webpage,
G. Cortini (Predappio, Italy, 0.35-m telescope) reports that the variable
appeared at mag 17.3 with position end figures 47s.08, 17.0 (offset 1″.3
east, 34″ north of the center of NGC 5430) on several unfiltered CCD images
(limiting mag about 18.5) taken on Oct. 6.81. S. Nakano, Sumoto, Japan,
forwards mag 17.0 and position end figures 47s.09, 16″.6 (offset 10″ east,
33″ north) from unfiltered CCD images (limiting mag 18.0) taken by K. Kadota
(Ageo, Japan, 0.25-m f/5 reflector + SBIG ST-9E camera) on Oct. 6.080. T.
Yusa, Osaki, Japan, reports mag 17.0 and position end figures 47s.10, 16″.7
(offset 10″ east, 33″ north of the center of NGC 5430) from unfiltered CCD
frames (limiting mag 18.5) taken on Oct. 7.402 with a 0.30-m f/7 Cassegrain
telescope (+ SBIG STL-1001E camera).
