Abstract: We confirm the validity of video observations to get the magnitude ratio of meteor showers by calculating the ratio of shower meteors to sporadic meteors.  The magnitude ratios obtained from the Global Meteor Network...

Abstract: We challenge to investigate the magnitude ratio (r) of 14 major meteor showers using SonotaCo net video data: Quadrantids (QUA#010), Lyrids (LYR#006), eta Aquariids (ETA#031), Southern delta Aquariids (SDA#005),...

Abstract: We confirmed the 5-year periodicity of the χ-Cygnids (CCY#0757) and find an increasing trend in the activity; the next return might be expected in 2025.  The chi Cygnid meteor shower displays activity mainly in the...

Abstract: The Global Meteor Network completely covered the outburst of the meteor shower related to 73P/Schwassmann-Wachmann 3.  The peak activity was recorded by camera operators in Western America when the radiant was at its...
