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.

Candidates numbered from 95 to 99 come from the search for new objects found on the difference images, whereas the candidates 100-106 were found on top of known sources. The latter search is run less frequently, therefore those supernovae are typically detected past their maximum brightness and their light curves are blended with the underlying light of the host galaxy.
