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.
