Abstract (from CDS):
Kamil Hornoch, Astronomical Institute, Ondrejov, reports his discovery of a possible nova in the galaxy M32 on a co-added 900-s R-band CCD frame taken on July 9.066 UT with the 0.65-m telescope at Ondrejov. The new object is marginally visible on single images used for the co-added frame and is visible also on a pre-discovery co-added R-band CCD frame taken by Hornoch and P. Hornochova with the same instrumentation on June 26.043, but it is not present on numerous archive images taken at Ondrejov and other observatories. The new object, designated M32N 2010-07a, is located at R.A. = 0:42:32.43, Decl. = +40:53:36.5 (equinox 2000.0), which is 107" west and 99" north of the center of M32. Available R-band magnitudes for M32N 2010-07a, as measured by Hornoch: 2001 Nov. 22.321, [22.3 (A. Crotts, 8.2-m Subaru telescope at Mauna Kea); 2006 Jan. 6.084, [21.5 (J. Gallagher and P. Garnavich, 0.91-m telescope at Kitt Peak); 25.086, [21.4 (Gallagher and Garnavich); 2009 Aug. 30.932, [21.2 (Hornoch, 0.65-m telescope at Ondrejov); 2010 June 26.043, 19.2 ± 0.25 (Hornoch and Hornochova, 0.65-m telescope at Ondrejov); July 9.066, 19.3 ± 0.2 (Hornoch); 16.954, 19.5 ± 0.15 (Hornoch and Hornochova).
