We present the light elements of three newly discovered eclipsing binaries. Their variability was detected during our observations of the variable AW Cru in 2013. All the observations were made at the Estación Astrofísica Bosque Alegre, in Argentina with a 1.54 meter reflector telescope and an unfiltered CCD camera. The reductions of the images were done using the Fotodif 3.93 software. We use two comparison stars USNO-A2.0 0225-13471141 and 0225-13461332 for the photometry; their red magnitudes from the USNO-A2.0 catalog (Monet et. al. 1998) were used.
