SN2006oz is a super-luminous supernova (SLSN) with a mysterious bright precursor. Such a precursor has been predicted in the dual-shock quark nova model of SLSN: the precursor is the SN event while the main light curve of the SLSN is powered by the Quark-Nova (QN; explosive transition of the neutron star to a quark star). As the SN is fading, the QN re-energizes the SN ejecta, producing the super-luminous part of the light curve. We show that this model can reproduce the observed double-peaked light curve of SN2006oz.
