Abstract: We present CRIRES observations of the “normal" carbon star TX Psc in the K, L and M bands, taken in 2010 and 2013. The spectro-astrometry shows clear signatures for the presence of a bright blob south of the star and several photospheric radii away. The flux ratio between blob and star is between 5% and 10%. This blob also shows up as an additional absorption component in the red wings of the CO lines.
