We present photometric and spectroscopic follow-up of a sample ofextragalactic novae discovered by the Palomar 60-inch telescope during a searchfor "Fast Transients In Nearest Galaxies" (P60-FasTING). Designed as a fastcadence (1-day) and deep (g < 21 mag) survey, P60-FasTING was particularlysensitive to short-lived and faint optical transients. The P60-FasTING novasample includes 10 novae in M31, 6 in M81, 3 in M82, 1 in NGC2403 and 1 inNGC891. This significantly expands the known sample of extragalactic novaebeyond the Local Group, including the first discoveries in a starburstenvironment. Surprisingly, our photometry shows that this sample is quiteinconsistent with the canonical Maximum Magnitude Rate of Decline (MMRD)relation for classical novae. Furthermore, the spectra of the P60-FasTINGsample are indistinguishable from classical novae. We suggest that we haveuncovered a sub-class of faint and fast classical novae in a new phase space inluminosity-timescale of optical transients. Thus, novae span two orders ofmagnitude in both luminosity and time. Perhaps, the MMRD, which ischaracterized only by the white dwarf mass, was an over-simplification. Novaphysics appears to be characterized by quite a rich four-dimensional parameterspace in white dwarf mass, temperature, composition and accretion rate.
