We report the discovery of supernova candidates from a transient survey with Subaru/Hyper Suprime-Cam (HSC). Our Subaru/HSC open-use observations were performed on 26 and 27 Nov 2014 UT. The candidates were detected in real time using a quick image subtraction system (ATel #6291). The reference images were obtained with HSC on 24 Sep 2014 UT.
