RR Tel, like other symbiotic miras, is a binary containing a giant, which is a mira variable, and a compact component. According to present day ideas, the latter is a white dwarf, accreting from the mira wind. The wind contains dust; during "obscuration events" absorption due to this dust increases temporarily. At present we are comparing relative fluxes of optical Fe II emission lines at two dates, of which one was during an obscuration event and the other not during such an event, in order to obtain information on the changes in the distribution of dust between the two dates and the physics involved.
