We present the results of a comprehensive effort to measure physical characteristics of 2003 YT1 during its close earth approach in April-May, 2004. The 2.34 hour rotation period can be seen in several nights of time series photometry during which the peak to peak amplitude varied as the observing geometry changed. The binary nature was noted in the Modra Observatory light curve of April 22.99UT, but observed directly in delay-Doppler images on May 1-4 (IAUC 8336, and Nolan et al., this meeting). We compare features seen in the radar images with the light curve.
