The OGLE-IV Transient Detection System (Wyrzykowski et al. 2014, AcA,64,197; Kozlowski et al. 2013; Klencki et al. 2016, AcA, 66,15) announces discovery of 49 new on-going and recently finished transients discovered since Jan 2017.

They appeared near or on top of apparent galaxies and their light curves resemble those of supernovae near or after their peak brightness. Most of the candidates were detected with our Rapid Transient Detection System within less than 15 mins from observation: http://ogle.astrouw.edu.pl/ogle4/transients/rapid/rapid.html
