4 Definition of Supernova Explosive event disrupting a star at the end of its (single or binary) evolution, returning to the Inter-Stellar Medium all (or most) the gas synthetized during its evolution and explosion.

9 Novae and Supernovae Novae observed since millennia in the East and in the West Few in Nebulae (S And 1885) Lundmark (1919) D(And)=200Kpc M SN1885 =-15 Lundmark (1925) It is quite possible that we have to deal with two distinct classes of Novae: one 'upper class' having comparatively few members and reaching an absolute magnitude more or less equal to the absolute magnitude of the system in which they appear: one 'lower class' in the mean 10 magnitudes fainter... Baade & Zwicky SuperNovae as final stages of Stellar Evolution, sources of cosmic rays and result of creation of NS (!!)
10 Historical SNe (Stephenson & Green 2005) Investigations of ancient (East and West) chronicles Criteria: 1. Long duration of visibility 2. Fixed location 3. Low b 4. No angular extent 5. Unusual brilliance 6. Independent records 7. (association with SNR)

13 SN discovery (SN 1998S)
14 Image to be searched Reference image Subtracted image SN 2000fc type Ia V=22.4 z=0.42 IAUC7537 Each image is the sum of three 15min exposures The search is based on the comparison of two images taken at different epochs. The image with the best seeing is matched to the other and the reference frame is subtracted using ISIS2.1 package. The difference image is searched for candidates using sextractor. Then we use a scoring algorithm tuned after artificial star experiment to sort the candidates.
