We have completed an internal calibration of 4.4 years of BATSE 10-20 keV SD data for Sco X-1. The resulting light curve shows variations on time scales from hours to weeks. A full description of the calibration used in arriving at this light curve has been submitted to the ApJ Supplement (McNamara et al. 1997). Fourier transform analysis of the resulting light curve found no significant periodicities on these time frames. Further period searches using short blocks of SD data, and the Gabor transform, is discussed in a companion paper by Mason et al. We have compared the BATSE SD Sco X-1 10-20 keV light curve to those produced by other missions/instruments and find that the amplitude of the variability of Sco X-1 increases with increasing energy. This result supports the suggestion of Mason et al. (1997a,b) that some positionally consistent catalogued gamma-ray bursts originate from Sco X-1 and Cyg X-1.
