The first results of detailed spectroscopy are presented for carbon Mira R Leporis. This long-period variable is undergoing deep fadings, apparently caused by dust formation around the star. High-resolution CCD spectra were observed for two seasons. The heliocentric photospheric radial velocity was found to be +32.6 and +38.4 km s-1, respectively. Blueshifted emissions from the circumstellar gas are seen.
