Notes. The listed streams are probably contributing with old meteoroids forming the annual shower plus some punctual encounters with young dust trails (the year indicated for each trail corresponds with the year of perihelion in which it was created). Known dust trail events are listed, indicating in bold the most favorable ones. Eccentricity (e) and perihelion distance (q) are also given from Jopek et al. (2003, 2010). vg indicates the geocentric velocity relative to the Earth which roughly corresponds to the impact velocity.
