Descripción
We present preliminary results of a simultaneous X-ray/optical campaign
of the proto-typical LMXB Sco X-1 at 1-10 Hz time resolution.
Lightcurves of the high excitation Bowen/HeII emission lines were
obtained through narrow interference filters with ULTRACAM, and these
were cross-correlated with X-ray lightcurves. We find evidence for
correlated variability, in particular when Sco X-1 enters the Flaring
Branch. The Bowen/HeII lightcurves lag the X-ray lightcurves with a
light travel time which is consistent with reprocessing in the companion
star.
