Cassegrain and coude spectrograms and simultaneous photoelectric UBV observations of the bright southern T Tauri star CoD -35 deg 10525 are described. The spectra show the redshifted absorption components and the complex structure of the Balmer emission lines which are characteristic of YY Orionis stars. No Fe II or Ti II emission or absorption lines could be detected. The He I and He II emission lines appear in unusual strength. The photometric observation reveal a strong ultraviolet excess and brightness variations of about 0.5 mag within a few days. The observations can be explained by the assumption that CoD -35 deg 10525 is a protostar of about the same mass as the bright YY Orionis star S CrA. The only significant difference between the two objects seems to be their evolutionary age. CoD -35 deg 10525 appears to be older by about 100,000 years.
