AB We present new orbital data and dynamic results pointing towards the origin of the Northernχ-Orionid meteoroid stream, which is a part of the Taurid meteoroid complex. A new softwarepackage was developed to establish the potential parent bodies of meteoroid streams basedon the similarity of their orbits. The analysis of a Northern χ-Orionid fireball observedon 2011 December 6 identified two potential parent bodies: the near-Earth object (NEO)2002XM35 (previously proposed as the parent of this meteoroid stream) and the more recentlydiscovered potentially hazardous asteroid 2008XM1. The calculation of the evolution of theorbital elements performed by using the Mercury 6 symplectic integrator supports the ideathat 2008XM1 is a better parent body. Our data sample was expanded by including also inthe calculations the mean orbit of the χ-Orionid stream. The results are consistent with thefragmentation of a larger body in the past that could give rise to both NEOs and the Northernχ-Orionid stream. To confirm this, further observations to improve the orbital elements ofthese asteroids should be attempted before the objects are lost. The analysis of the emissionspectrum recorded for this fireball supports a primitive nature for these meteoroids.
