46442 Keithtritton           Discovered 2002 June 12 by C. W. Juels and P. R. Holvorcem at Fountain Hills.
Keith Tritton (b. 1944) optically identified and monitored radio galaxies and quasars while he was an observational astronomer at the Royal Greenwich Observatory from 1967 to 1997. The discoverers recently found his lost short-period comet D/1978 C1, now numbered 157P.
