The OGLE-IV Transient Detection System (Wyrzykowski et al. 2014, AcA,64,197; Kozlowski et al. 2013) reports the discovery of 24 new on-going transients. Most of them appeared near or on top of apparent galaxies and their light curves resemble those of supernovae near or after their peak brightness.
