Analysis of the SonotaCo video meteoroid orbits

TL;DR

This paper analyzes the Japanese SonotaCo video meteor data to assess the quality of meteoroid orbits and distinguish shower meteors from sporadic background, enhancing understanding of meteoroid streams.

Contribution

It provides a detailed analysis of the qualitative aspects of meteoroid orbits derived from a large, accessible multi station video meteor database in Japan.

Findings

Assessment of orbit accuracy and quality

Method for separating shower from sporadic meteors

Insights into meteoroid stream characteristics

Abstract

Since 2007 the Japanese video network provided significant amount of meteor data observed by multi station video meteor network located in Japan. The network detects meteors mostly up to +2 magnitude and is probably the most accurate and largest freely accessible video meteor database up-to-date. In this paper we present our analysis on the qualitative aspects of the meteor orbits derived from the multi station video observation and the separation of the shower meteors from the sporadic background.
