We report observations of an unpredicted fine structure in the activity profile of the Leonid meteor storm of 1999 November 18. Our observations were obtained at three widely separated sites (on the Iberian peninsula, in Germany, and in Northern Sweden) and with two totally different techniques (video cameras and meteor radars). The observations clearly show quasi-periodic variations of the meteor rate with temporal separations of individual maxima in the 6- to 9-min range. ...

... The binary nature was remarked by Deutsch, approximate orbital elements were at first derived in Potsdam. Recently, 53 Cam was directly resolved by speckle-interferometric measurements of McAlister et al. and Balega. Combining with the spectroscopic elements the determination of the absolute values of the system parameters should be possible. In the present paper a revision of the spectroscopic orbital elements and a comparison of spectroscopic and speckle data have been carried out. ...
