Photometry of HD 153919 = 2U 1700-37.
Abstract
UBVJHKL photometry of lID 153919 is presented. The star is a variable with a period of 34120 days, equal to the X-ray period. The variation has two minima of equal depth but of differing shape. One minimum is coincident with the X-ray occultation. There is an infra-red excess. The implication of these observations is discussed.
