We present the following observations of Wra 220, the H-alpha emission line star seen superposed on cometary globule 22 (CG22) on the ESO-SERC IIIaJ plates: (1) low resolution blue and red spectra (2) high resolution spectra in the region of the H-alpha 6563 A line (3) NIR photmetry (4) visual photometry from CCD images (5) IRAS Point Source Catalog data. Based on these data, we conclude that Wra 220 is a T-Tauri star physically associated with CG22. Other properties of the star like luminosity class, spectral energy distribution, etc. have also been derived.
