The x-ray, optical, and radio behavior of Scorpius X-1: The 1972 coordinated observations

Description

We present the results of a 10-day observation of Scorpius X-1 involving seven optical stations, NRAO, and the MIT experiment on the OSO 7 satellite. The source exhibits all of its characteristic variability, including flares and quiescent periods. There is clear evidence for an X-ray-optical correlation in that X-ray activity occurs only where the object is brighter than m/subB/approx. =12.7. However, detailed comparisons of X-ray and optical flares do not show a strict correlation between the intensities, with the exception of one approx.20-minute X-ray flare which lags 2 to 3 minutes behind a triple optical flare of similar overall duration. There is no apparent correspondence between two radio flares observed and the shorter wavelength activity
