ResumoA strong meteor shower was observed by members of the Nippon Meteor Society (NMS) during the evening of October 8, 1985, across Japan which was believed to be a display of the Giacobinids, the first strong display in Japan since the 1965 Leonids. Favorable weather allowed several types of observations to be made. Most observations were visual but some were made telescopically or photographically. FM radio and TV camera techniques were also used. The data obtained by observations and by photography are analyzed below. Main results are as follows: (1) Considering the position of the radiant and the orbital elements of the meteors, the shower was undoubtedly the Giacobinids. (2) The maximum zenithal hourly rate of the shower was 154 at 10h10m UT. This rate was, however, much lower than 5000 during the display of the Giacobinids in 1933 or in 1946.
