RW Triangulum (RW Tri) is a 13th magnitude Nova-like Cataclysmic Variable star with an orbital period of 0.2319 days (5.56 hours). Infrared observations of RW Tri indicate that its secondary is most likely a late K-dwarf (Dhillon 1998). Past analyses predicted a distance of 270 parsec, derived from a black-body fit to spectrum of the central part of the disk (Rutten et. al, 1992). Recently completed Hubble Space Telescope Fine Guidance Sensor interferometric observations allow us to determine the first trigonometric parallax to RW Tri. This determination puts the distance of RW Tri at 341 −31 +38 , one of the most distant objects with a direct parallax measurement. We compare our result with methods previously employed to estimate distances to CV's.
