Abstract

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.
