HiTS: The High Cadence Transient Survey (ATELs #5949, #5956, #7099) reports the discovery of one additional supernova candidate detected using a novel real-time high-cadence image subtraction / classification pipeline developed at the Center for Mathematical Modelling (CMM) in collaboration with the Millennium Institute for Astrophysics (MAS). Observations were performed on the 4m Blanco Telescope at Cerro Tololo (CTIO) using the Dark Energy Camera (DECam). The data analysis was performed in real-time using the National Laboratory for High Performance Computing (NLHPC). The candidate SNHiTS15I was seen rising from UT 2015-02-17 03:59 to UT 2015-02-20 02:08 and may have been present before our first observation. Based on the image difference we estimate a magnitude of at least 22.05+-0.12 in g band in the last observation. No additional observations could be obtained in UT 2015-02-20 due to bad weather.
