Possible new cataclysmic variable in Ursa Major.

YAMAOKA H. and ITAGAKI K.

Abstract (from CDS):

H. Yamaoka, Kyushu University, reports the discovery by K. Itagaki (Yamagata, Japan) of a previously unknown variable star on a wide-field survey CCD image taken on Jan. 2.727 UT with a 0.21-m f/3 reflector. Confirming CCD images taken on Jan. 2.749 with a 0.30-m f/7.8 reflector show the variable's magnitude to be about 14.9 and its position to be R.A. = 10h26m37s.04, Decl. = +47d54'26".3 (equinox 2000.0). The star was fainter than mag 16.5 on his survey image taken on 2008 Jan. 31.627. A faint blue star in the Sloan Digital Sky Survey (magnitudes u = 20.2, g = 20.1, r = 20.1, i = 20.2, z = 19.9), has a catalogued position that is identical with the reported object. The outburst amplitude and the color at its quiesient phase suggest that the variable is possibly a dwarf nova caught in outburst.
