Abstract
The comet Austin (1984I) discovered on July 8, 1984 was observed at the European Southern Observatory on July25.97UT (O.50m reflector and Stromgren photometer),and July27.96UT(1.5m reflector, Boller & Chivens spectrograph and image Dissector Scanner in the spectral range 500-730 nm ). Several spectra along the solar-antisolar axis have been taken, showing the spatial extension of the species C2, NH2, Na I, H2O+, O I lines.The central diffuse condensation of FWHM 25" , the spatial behaviour of the previous species and the additional emitting features included in the photometric Stromgren bands are discussed
