Abstract
We discuss the recent outburst of nova LMC 1991. By comparing its magnitude at maximum and rate of decline with those of 14 historical LMC novae, we show that nova LMC 1991 represents the first detection of a super-bright nova in the Large Magellanic Cloud. We have critically reviewed the photometric properties of the nova population in the Galaxy, M31, LMC and Virgo Cluster, and find that 9 objects deviate systematically from the Magnitude at Maximum vs. Rate of Decline relation by about one magnitude. This result may imply the existence of a distinct family of super-bright novae.
