POSSIBLE NOVA IN M33
     R. Quimby, P. Mondol, and F. Castro, University of Texas, report
the discovery of an apparent nova on unfiltered CCD images taken on Sept.
28.20 (at mag about 17.3) and 29.20 UT (mag about 16.9) using the 0.45-m
ROTSE-IIIb telescope at the McDonald Observatory.  The apparent nova is
located at R.A. = 1h33m18s.66, Decl. = +30o49'49".2 (equinox 2000.0),
which is 6'56".0 west and 10'13".4 north of the center of M33.  A
co-addition of ROTSE-IIIb images taken between 2005 July and 2006 Jan.
shows nothing at this position (limiting mag about 19.0).
     S. Nakano, Sumoto, Japan, reports the independent discovery of this
apparent nova at mag 16.6 by K. Itagaki (Teppo-cho, Yamagata, Japan) on
unfiltered CCD frames taken around Sept. 30.684 UT with a 0.60-m f/5.7
reflector.  Itagaki provides position end figures 18s.74, 48".1 for the
new object.  Nothing is visible on a frame taken by Itagaki on Sept. 23.69
(limiting mag 18.5) or on his many past survey frames.
