The OGLE-IV Transient Search (Wyrzykowski et al. ATEL #4495, Kozlowski et al. 2013) reports the discovery of 12 new on-going candidates for supernovae. Most of them appeared near or on top of apparent galaxies and their light curves resemble those of supernovae before or near their peak brightness. Some of the transients have no host visible on the reference OGLE-IV images (depth about 21.5 mag i I-band).
