Analysis of Perseid activity from short time visual count intervals

  • Jürgen Rendtel


During periods of high meteor rates (> 100...400 per hour), visual observers can gather substantial samples in intervals of less than 20 minutes or so. This seems to allow to find real particle flux variations occurring in the meteoroid stream. Investigations of the 1993 and 1994 Perseid peak counts suggest that interval lenghts of 10 minutes are recommended for close to the peak periods. Perception effects increase the scatter of ZHRs obtained from < 10 minute counts. Thus flux variations occurring at scales of ≥ 50,000 km may be detected by visual 10 minute meteor counts.
