The OGLE-IV Transient Detection System
(Wyrzykowski et al. 2014, arXiv:1409.1095; Kozlowski et al. 2013)
reports the discovery of
12
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.
