la Supernova 1999el dans NGC 6951
L. Cao, Y. L. Qiu, Q. Y. Qiao, and J. Y. Hu, Beijing Astronomical Observatory
(BAO), on behalf of the BAO Supernova
Survey, report the discovery of an apparent supernova (mag about 15.4) in NGC
6951 on an unfiltered CCD frame taken on Oct. 20.45 UT
with a 0.60-m telescope at Xinglong station; an image taken on Oct. 21.44
yields mag about 15.0 (there is a knot at the location of SN
1999el on the Digital Sky Survey image and on previous BAO images, and the
magnitude estimates include the brightness of the supernova
and the knot). SN 1999el is located at R.A. = 20h37m17s.83, Decl. =
+66o06'11".5 (equinox 2000.0), which is 21".8 east and 8".4
south
of the nucleus of NGC 6951.
La galaxie est circumpolaire et la magnitude de la SN1999el peut atteindre
suivant le cas: SN Ia: 13.0 ou SN II: 15.0 ou hypernova: 11.0.
