APPARENT NOVA IN M31: M31N 2010-10e
Kamil Hornoch, Astronomical Institute, Ondrejov, and P. Hornochova report
their discovery of apparent nova in M31 on a co-added 1800-s R-band CCD frame
taken on Oct. 31.727 UT with the 0.65-m telescope at Ondrejov. The new
object, designated M31N 2010-10e, is well visible on the co-added frame as
well as on single images used for the co-added frame, but it is not present
on numerous archive images taken at Lelekovice and Ondrejov. The object is
visible also on a pre-discovery Ondrejov R-band CCD frame taken on Oct. 30.703
UT. M31N 2010-10e is located at R.A. = 0h42m57s.74, Decl. = +41o08'12".1
(equinox 2000.0), which is 151" east and 476" south of the center of M31.
Available R-band magnitudes (unless otherwise noted) for M31N 2010-10e,
measured by Hornoch: 2010 Oct. 28.703 UT, [21.1 (K. Hornoch and M. Wolf,
0.65-m telescope at Ondrejov); 29.711, [21.4 (Hornoch, 0.65-m telescope at
