65100 Birtwhistle           Discovered 2002 Feb. 8 by C. W. Juels and P. R. Holvorcem at Fountain Hills.
British amateur astronomer Peter Birtwhistle (b. 1958) was measuring positions of comets and NEAs photographically during 1982-1986 and in 2002 began CCD astrometry in Great Shefford, Berkshire. On 2003 Sept. 29 he provided confirmation of 2003 SQ222, whose passage at 84~000 km from the earth is the closest known.
