>The meteor shower activity was observed at Triangulum on September 12
>and 15, 1998 in Japan. K.Osada plotted 9 shower meteors from Triangulum
>on September 12 and M.Sakaguchi plotted 6 shower meteors from there on
>September 15. I think that it was probably the same activity of
>Triangulids which was observed on September 12, 1993 in America (Sky and
>Telescope, October 1994).
