Sažetak
We have examined the changes of line fluxes of RR Tel in the optical spectra taken in 2000 compared with the corresponding ones of the spectra taken in 1996. The fading of the lines leading to the apparent decrease of the radius of the line emitting region can be understood as being spurious and explained by increased circumstellar dust absorption in the stellar wind of the mira. This dust obscuration event has given clues about stratification effects in the emitting region. In addition, infrared photometry performed in South Africa shows a change in the nature of colour behaviour. It is not yet clear if that is due to a change in dust properties.
