Abstract :
The calculation of the orbit of the potentially hazardous Asteroid 2001 YB5 suggests a possible meteor shower around January 7.5, 2002 UT. Video observations revealed an unidentified radiant around the predicted maximum time, at RA=121.5°, Dec=+11.5°(for solar longitude 287.30°). Visual observers also reported unusually high rates from that region on the same night, indicating that 2001 YB5 did produce a weak meteor shower. Furthermore, it is noticed that 2001 YB5 is a rare B-type asteroid in same spectral class with Asteroid (3200) Phaethon, the parent body of the only previously known asteroid-associate meteor shower, Geminids.
