Minor planet 1993SC, with a semi-major axis of 39.67 AU, is one of the brightest of numerous recently discovered objects with orbits close to or beyond Neptune. It is a member of the Kuiper Belt, a planetesimal population remaining from the formation of the Solar System. We present optical photometry which indicates a lightcurve amplitude of less than 0.2 magnitude for 1993SC and which does not support the 0.5 magnitude lightcurve of I. P. Williamset al.(Icarus116, 180-185, 1995). We derive (Kron-Cousins photometric system)V - R= 0.54 +/- 0.14,V - I= 0.97 +/- 0.14, andV - J= 2.08 +/- 0.15, which confirm that 1993SC has optical/infrared colors closer to Centaur 1993HA 2 than to the extremely red 5145 Pholus. We also find that VRI colors published by J. X. Luu and D. C. Jewitt (Astron. J.111, 499-503, 1996) are inconsistent with their reflectance spectrum of 1993SC and we derive new values from their reflectance spectrum ofV - R= 0.56 +/- 0.08 andV - I= 1.19 +/- 0.18, which give reasonable agreement with our results.
