Top: a comparison of Nov. 20 STIS ultraviolet spectrum of Nova Mon 2012, E(B − V) = 0.85 (solid) and V1974 Cyg SWP 45245, E(B − V) = 0.36, day 165 (dash). Bottom: comparison of the optical spectra of Nova Mon 2012 (2012 Nov. 21, NOT; solid) and V1974 Cyg, (1992 Sep. 25; dash), corrected for their respective extinctions. No scaling corrections have been applied but the NOT spectrum was binned to the resolution of the V1974 Cyg spectrum.
