Long-term photometric monitoring (specifically, V-band absolute magnitudes) for extra-Galactic LRNe discussed in this paper, covering about a decade of their evolution. Pre- and post-discovery detection limits are indicated with “down-arrow” symbols. The phase is in days from the first (blue) peak in the V band. The absolute light curves of LRN outbursts are compared in detail in Sect. 5.2.
