I reported to the CBAT as below.
Itagaki-san reported his detection of an apparent new stellar object
(unfiltered mag 13.0) on Jan. 9.430 UT. He reported the position as
R.A. = 22h57m49s.57, Decl. = -08d22'27".9. It should be an outburst
of a star SDSS J225749.54-082228.7, which is tabled in some catalogs
(USNO A2.0, USNO B1.0, GSC 2.3 and so on) as a star with mag about 20.
Like as KT Eri, the amplitude of seven magnitudes is rather large for
a dwarf nova, but somewhat small for a rapid classical nova.
