We present griz lightcurves and spectra for two ultraluminous supernovae from the Supernova Legacy Survey (SNLS). SNLS-06D4eu, at a redshift of z=1.588 is one of the most luminous supernovae known, with MU=-22.7, a luminosity of 3.4 x 1044 erg/s, and a total radiated energy of 1051 erg. It is also the highest redshift supernova with a spectrum. SNLS-07D2bv, at z 1.5 is similar. The four-filter, few-day cadence of the SNLS, and high redshifts provide the most in-dept look yet at the ultraviolet emission from these UV-bright events. These supernovae, 100 times brighter than a normal core-collapse supernova, are difficult to explain with current theory. We consider explanations involving radioactive decay, power via circumstellar interaction, and the creation and spin-down of a magnetar.
