We report the discovery of a probable nova in M83 on a co-added 720-s R-band CCD frame taken on 2019 Mar. 5.405 UT with the Danish 1.54-m telescope at La Silla.
The new object designated PNV J13371818-2948290 is located at R.A. = 13h37m18s.18, Decl. = -29o48'29".0 (equinox 2000.0), which is 224.6" east and 207.7" north of the center of M83 (see link to finding chart below) and is visible also on several prediscovery images taken with the same instrumentation.
The following R-band magnitudes (unless otherwise noted) were obtained using the Danish 1.54-m telescope at La Silla:
2018 Mar. 26.207 UT, [24.0; 2019 Feb. 6.394, [22.7; 18.399, 22.0 ± 0.4; Mar. 1.406, 22.2 ± 0.4; 2.282, 22.0 ± 0.2; 4.404, 21.9 ± 0.25; 5.405, 22.2 ± 0.3; 6.405, 22.0 ± 0.3; 8.403, 21.9 ± 0.3 (I-band).
This work is based on data collected with the Danish 1.54-m telescope at the ESO La Silla Observatory.
