RR TrA is an Algol-type eclipsing binary with a period of 0d.7131. The components are believed to be of spectral types B8 V and F0 IV. The analysis presented is based on previously unreduced observations made by Somerville in 1961 - 63. Orbital elements are obtained using the Wood model, and these indicate that the system is semi-detached, and that the eclipses are marginally complete. The components appear to be of unusually small size for their spectral classes. The solution presented is compared with earlier ones for this system obtained by Kwee and Giuricin and Mardirossian, and similarities and differences between these solutions are noted.
