The OGLE-IV Transient Search (Wyrzykowski et al. ATEL #4495, Kozlowski et al. 2013)
reports the discovery of seven new on-going transient candidates.
The four of them appeared near or on top of apparent galaxies
and their light curves resemble those of supernovae near their peak brightness.
The remaining two are probably another supernovae with the hosts not visible on the OGLE
images, and a nova (or large amplitude dwarf nova) outburst in the Magellanic Bridge.
