Initial Statistics from the Perth Automated Supernova Search

  • Andrew J. Williams (a1)

The Perth Automated Supernova Search uses the 61-cm PLAT (Perth Lowell Automated Telescope) at Perth Observatory, Western Australia. Since 1993 January 1, five confirmed supernovae have been found by the search. The analysis of the first three years of data is discussed, and preliminary results presented. We find a Type Ib/c rate of 0·43±0·43 SNu, and a Type IIP rate of 0·86±0·49 SNu, where SNu are ‘supernova units’, expressed in supernovae per 1010 LB galaxy per century. These values are for a Hubble constant of 75 kms−1 Mpc−1, and scale as (H 0/75)2.
