We present results from a campaign of simultaneous X-ray and optical observations of X1254 - 690 conducted using the Rossi X-ray Timing Explorer and the CTIO 1.5m telescope .
We find that the usually-observed deep X-ray dipping is not seen during the times of our observations , with an upper limit of \sim 2 % on any X-ray orbital variation , and that the mean optical variability has declined in amplitude from \Delta V =0.40 \pm 0.02 mag to 0.28 \pm 0.01 mag .
These findings indicate that the vertical structure on the disk edge associated with the impact point of the accretion stream has decreased in angular size from 17–25 ^ { o } to < 10 ^ { o } , and support the suggestions of previous modeling work that the bulge provides 35–40 % of the contribution to the overall optical modulation .
The average optical and X-ray brightnesses are comparable to their values during dipping episodes , indicating that the mean \dot { M } and disk radius remain unchanged .
