We report the discovery of a probable nova in M83 on a co-added 1200-s R-band CCD frame taken on 2018 Jan. 28.263 UT with the Danish 1.54-m telescope at La Silla.

The new object designated PNV J13370978-2956576 is located at R.A. = 13h37m09s.78, Decl. = -29o56'57".6 (equinox 2000.0), which is 115.2" east and 300.9" south of the center of M83 (see link to finding chart below).

The following R-band magnitudes (except otherwise noted) were obtained using the Danish 1.54-m telescope at La Silla:

2017 Dec. 23.363 UT, [22.9; 2018 Jan. 28.263, 20.71 ± 0.08; 29.278, 20.86 ± 0.09; 29.290, I = 20.7 ± 0.1.

This work is based on data collected with the Danish 1.54-m telescope at the ESO La Silla Observatory.
