X-ray dippers are high inclination low mass X-ray binaries where azimuthal structure on the accretion disk extends vertically above the plane of the binary and periodically blocks the line of sight to the central X-ray producing regions. Optical emission from these systems also varies on the orbital period, but originates largely from reprocessing of X-rays in the outer system. Since these different energy regimes correspond to different physical locations within the binary, multiwavelength observations provide a complete picture of the emission regions and accretion disk geometry. We propose to perform optical and X-ray studies of the dipper X1624-490, utilizing the CTIO 0.9m telescope along with RXTE. X1624-490 may be the most interesting X-ray dipper known: its persistent emission is the brightest, its 21-hr period the longest, and its dip profiles the most erratic in its class. We have only recently identified a tentative optical counterpart to X1624-490 which -if confirmed- would imply an orbital period twice as long as previously believed and dramatically alter the assumed accretion disk structure.
