Subtypes[edit]
Novae are classified according to the light curve development speed, thus in
NA: Fast novae, with a rapid brightness increase, followed by a brightness decline of 3 magnitudes — to about 1⁄16 brightness — within 100 days.[11]
NB: Slow novae, with a 3 magnitudes decline in 150 days or more.
NC: Very slow novae, staying at maximum light for a decade or more, fading very slowly. It is possible that NC type novae are objects differing physically very much from normal novae, for example planetary nebulae in formation, exhibiting Wolf-Rayet star like features.
NR/RN: Recurrent novae, novae with two or more outbursts separated by 10–80 years have been observed.[12]

Found another link with some really good info on the nova.

Really hate I can't pull the telescope out and view this.
