THE IDENTIFICATION OF METEOR SHOWERS WITH APPLICATION TO SOUTHERN HEMISPHERE RESULTS
CANTERBURY UNIV CHRISTCHURCH (NEW ZEALAND)
Pagination or Media Count:
Further meteor shower results observed by radar at Christchurch, New Zealand, are given including results at high rates, and data are compared with visual observations and radar results from Adelaide for the declination range from 26 degrees .5 to about -50 degrees. Seven meteor showers appear in all three surveys, and can be regarded as certain and another 6 to 9 which are each reported twice are probable. An additional 9 to 10 radiants, however, are found by each survey alone. The technique of shower identification depends partly on the nature of the background rate, which may be due either to sporadic meteors or to the resultant of many minor radiants. The resolution of this uncertainty is necessary before the occurrence of less active showers can be confirmed. The ratecount method has been extended to multiple range bands, resulting in a useful additional means of sorting out the significance of peaks in the rate curves. Author
