Radar observations of the 1985 return of the Giacobinid meteor shower were carried out at the Onsala Space Observatory in Sweden. The observations showed that the shower was of approximately 3h duration, rising steeply to a maximum at 09h35m UT on 1985 October 8. The meteor shower thus showed the same short period characteristics as the intense showers of 1933 and 1946. Peak meteor echo rates of 75 occurred in the tenminute interval 09h30m−09h40m UT. The corresponding shower zenithal rate at maximum after removal of background activity was 484 echoes per hour. The longitude of the descending node of the shower at maximum was 194°.55 (equinox 1950). The plane of the central part of the 1985 shower was displaced by 0°.15 in longitude with respect to the orbital plane of the comet.
