Jupiter Family Meteor Showers by SonotaCo Network Observations

I investigated Jupiter family meteor showers using fourteen years of records, 2007 till 2020, from the database of the Japanese automatic TV meteor observation network, the ``SonotaCo network''. Out of the results, 38 meteor showers have been published as ``established meteor showers'' at the IAU Meteor Data Center, 17 meteor showers were on the IAU MDC working list and 1 new meteor shower's elements were found. Comparing this study and the IAU MDC, I propose two improvements for the IAU MDC registration process: (1) To register meteor showers at the IAU MDC by checking four requirements involving scientific data, the shower's existence, the shower's independence from already known showers, and the research's objectivity; and (2) In the shower's ``Activity'' classification, adding a new division ``periodic'' or ``resonance'' to the current categories of ``annual'' and individual years.
