C. Jackson found Xosa in 1939 May while working in Johannesburg. The name is that of a South African tribe. The asteroids orbit has a semi-major axis of about 2.55AU and inclination of 12.5. Its size is estimated to be about 14-15km but its spectral classification has not yet been determined.
The effort to determine the period of this asteroid was truly collaborative as both authors contributed data towards finding a lightcurve. Robinsons data was acquired on 2001 July 29 and August 3 while Warner worked the asteroid 2001 July 25 and August 8. Data was also obtained on other nights but was either dominated by noise or too short of coverage to contribute effectively to a solution.
