We continue our investigation of the emitting region of the symbiotic nova RR Telescopii by analyzing the emission line fluxes from high quality AAT optical spectra obtained in 2000 and comparing these with previous observations. The fading found in the recent spectra suggests increased circumstellar dust absorption in the stellar wind of the mira. Differing absorption of lines formed in different regions provides information on the geometry of the dust regions. The radii of the Fe II emitting region obtained by the SAC method have been corrected for the dust obscuration.
