. Number of Supernovae discovered by amateurs. In this page the amateurs' contribution in supernovae discoveries is shown. The SN 1957B was the first supernova discovered by an amateur astronomer: Giuliano Romano. He discovered it with his own 0.40 mt. telescope at Treviso (Italy), then later he become a professional. This graph is updated to SN 2000ek . Yellow values are SNe discovered by amateurs, red ones the total number of SNe discovered for each year .

... In order to compare the number of different evolutionary stages obtained and X-ray luminosity of the chosen X-ray sources with the observed galactic values we use the sum of C/O+O/C , where C and O are the calculated and observed values of a given binary type, respectively. If we make comparison for a number of different binary species (for example, we compare the number of CV, number of X-ray pulsars,   total X-ray luminosity of LMXB, etc.), we write this criterion in the form: . ...
