Abstract :
This paper presents an analysis of recent and historic supernovae and the statistics found in multiple supernovae occurrences, as related to the apparent time intervals between successive events, and the application of trends found from those simple statistics to supernova surveying-a focused search: developing target lists from the International Astronomical Union (IAU), list of all known supernovae and their host galaxies, with the greatest immediate statistical potential for a timely successive supernova. This approach has yielded consistent results for target development since its inception, with a 96% success rate over 16 months, and one direct, and immediate, result for surveying (SN2002eg). These trends found in apparent time intervals have been seen to apply to known hosts with only one recorded supernova and not otherwise known to be "prolific" supernovae producers. This strong indication of applicable periodic behavior introduces a potential new role for extra-galactic supernovae, in modern cosmology, as possible observational evidence in support of the plasma cosmology theory of Hannes Alfven, based on fundamental principles.
