NA = Fast nova, Time3-time smaller than 100 days, spectroscopically confirmed NB = Slow nova, Time3-time larger or equal than 100 days, spectroscopically confirmed NC = Extremely slow nova, typical time scale: decades N = Nova; light curve too poorly known to establish speed classThe following additions are used:
: = nova, not confirmed by spectroscopic observations ? = existence of object based on one photographic or a few independent visual observations ?? = existence based on no more than two visual observationsOther types of variability (objects once announced to be novae, but reclassified after more observations were obtained):
NR = Recurrent nova NL = Novalike variable (inhomogeneous group) UG = U Geminorum variable (dwarf nova) UGSS = U Geminorum variable, SS Cyg subclass UGSU = U Geminorum variable, SU UMa subclass UGZ = U Geminorum variable, Z Cam subclass UGWZ = U Geminorum variable, WZ Sge subclass (not yet official subclass) ZAND = Symbiotic variable (Z And type) XND = X-ray nova (transient) system consisting of a compact component and a dwarf or subgiant star with spectral type G to M M = Mira star (long-period variable of large amplitude) UV = UV Ceti type star (flare star) FU = FU Ori type star (pre-main sequence) SDOR = S Dor type star (Hubble-Sandage variable)
