We report the discovery of a probable supernova in the galaxy LEDA 906122
on a series of 180-s R-band CCD images taken between 2017 Mar. 22.155-22.392 UT
with the Danish 1.54-m telescope at La Silla. There is no object visible on
a deep stack of g'r'i' PanSTARRS1 images (Chambers, K.C., et al. 2016) available via the MAST Portal.
The new object designated PSN J12140783-1549026 is located at R.A. = 12h14m07s.83,
Decl. = -15o49'02".6 (equinox 2000.0), which is 3.2" east and 2.2" south of the center
of the host galaxy (see link to discovery image below which is co-added from eight
single 180-s R-band exposures).
Using several Landolt standard stars in a photometric conditions we measure
R = 19.22 ± 0.08 for the object on the co-added image centered on Mar. 22.211 UT.
This work is based on data collected with the Danish 1.54-m telescope
at the ESO La Silla Observatory.
