Abstract
The spectroscopic binary P Cygni star HD 152667 lies close in the sky to the X-ray source Sco X-2. We have analysed the existing photometry of this star and find that two solutions are possible. One is a conventional one and predicts that the unseen secondary is a B3 V star. The alternative solution suggests that all photometric variations are due only to one, gravity darkened star filling its Roche lobe and accompanied by what could be a dense, massive companion. HD 152667 has many similarities to HDE 226868 which has been identified with the X-ray source Cyg X-1.
