CCD observations of the jet of the quasar 3C 273

B and R broadband CCD photometry of the jet of 3C 273 is presented. Several knots are found within the jet. The knots at either end have a difference in color indices, with the knot at the outermost end being redder by about 1/2 magnitude in (B-R). Also, a variation in color may have been observed along the jet. This latter result would place constraints upon the jet-forming mechanism involved; the variation in color may be due to a nonthermal emission decay process. 28 references
