M$1 Answer
As of June 17, 2009, a total of 5129 supernovae have been observed, four of which have occurred in our galaxy.
Since supernovae cannot be accurately predicted (and in many cases the star is too faint to see until it becomes a supernova), they are found at random, either through dedicated sky surveys or by visual observers. In either case, the sudden appearance of an unexpectedly bright star is reported to the International Astronomical Union's Central Bureau for Astronomical Telegrams (although they do accept email), which then notifies astronomers worldwide so that the suspect object can be studied and either confirmed or ruled out as a supernova.
