We report the discovery of 4 possible supernova explosions detected using a novel real-time high-cadence image subtraction pipeline developed at the Center for Mathematical Modelling (CMM) in collaboration with the Millennium Institute for Astronomy (MAS) and the Department of Astronomy at Universidad de Chile. Observations were performed on the 4m Blanco Telescope at Cerro Tololo (CTIO) from 2014 02 28 to 2014 03 04 using Dark Energy Camera (DECam).

We estimate a limiting magnitude of 24 in the g band, and an astrometric precision <0.5" in the reported coordinates.
