We report the discovery of a probable supernova in the galaxy SDSS-DR12 J041606.28-054030.3
(Alam, S., et al. 2015)
on a series of 130-s R-band CCD images taken between 2021 Oct. 27.309-27.365 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 nor in a deep (SDSS-DR10 image).
The new object designated PSN J04160610-0540324 is located at R.A. = 4h16m06s.10,
Decl. = -5o40'32".4 (equinox 2000.0), which is 2.7" west and 2.2" south of the center
of the host galaxy (see link to discovery image below which is co-added from seven
single 130-s R-band exposures).
Using several Landolt standard stars in a photometric conditions we measure
R = 20.7 ± 0.1 for the object on the co-added image centered on Oct. 27.333 UT.
This work is based on data collected with the Danish 1.54-m telescope
at the ESO La Silla Observatory.
