We present an analysis of archival Gemini g', r', K and Keck H, K_s imaging of this nearby short-period binary (P_B = 95.8 minutes) 2.87 ms pulsar. The heated companion is clearly detected. Direct pulsar heating provides an acceptable model at the revised >700 pc parallax distance. The relatively shallow light curve modulation prefers an inclination i < 40°; this high-latitude view provides a likely explanation for the lack of radio signatures of wind dispersion or eclipse. It also explains the low minimum companion mass and, possibly, the faintness of the source in X-rays and γ-rays.
