Fig. 2

Leonid radiants during the maximum on November 17, 2009. The observed radiants are shown with their errors and compared with theoretical radiants for the 1466 and 1533 trails (Vaubaillon et al. 2009), with the annual Leonid radiant at solar longitude 235.55° according to Cook (1973) (C), Kresák & Porubčan (1970) (KP), Lindblad et al. (1993) (LPS), Porubčan & Gavajdová (1994) (PG), and Shrbený & Spurný (2009) (SS, radiant almost identical to KP). The filament circle as observed in 2006 (Jenniskens et al. 2008) is also shown. All coordinates are given in the equinox J2000.0.
