POSSIBLE DWARF NOVA IN HYDRA
     H. Yamaoka, Kyushu University, reports that K. Itagaki (Yamagata, Japan)
has discovered a variable star (mag 13.3) on unfiltered CCD images obtained
with a 0.21-m reflector on Jan. 19.592 UT, the "new" object located at R.A.
= 8h45m55s.08, Decl. = +3o39'29".7 (equinox 2000.0; photometry and astrometry
apparently measured from an image obtained with a 0.30-m reflector).  Nothing
is visible at this position on an image taken by Itagaki on 2007 Oct. 17
(limiting mag 17.5).  An image on Jan. 25.516 by Itagaki shows that the star
had faded to mag about 14.2.  The USNO-B1.0 and GSC 2.3.2 catalogues contain a
faint (mag about 20.0) star within 1" of the reported position.  H. Maehara,
Kyoto University, reports (via VSNET) that this variable star shows a
small-amplitude (about 0.1 mag) modulation.  A. Henden, AAVSO, notes (AAVSO
Special Notice 94) that the star is likely to be a WZ Sge-subclass variable.
