- there is roughly 30 novae per year in the Milky Way and about 20 in other galaxies
- absolute magnitude <math>M_V = -8 mag</math>
- amplitude between 6 and 15 mag
- quick rise of few days
- slow decline, between few days and 100 days (fast: type A, slow: type B, very slow: type C)
- 15 days after maximum its Mv = -5.5mag, independent on speed or class
