On July 4 2005 the NASA spacecraft Deep Impact delivered an impactor on the comet 9P Tempel 1 to study the material underneath the surface of the nucleus A worldwide observation campaign accompanied the mission to characterize the activity of Tempel 1 before and after the impact At La Palma Canary Islands the comet was observed from July 2 to July 9 using the echelle spectrograph SARG on the Telescopio Nazionale Galileo TNG The spectra have been obtained using a slit 8 arcsec long providing a resolving power R 29000 in the spectral range 4620-7920 A Most of the lines found in the spectra can be attributed to C2 NH2 and CN the atomic oxygen lines both the green line at 5577 A and the red doublet at 6300 and 6364 A are clearly visible in every spectrum All these emission lines have been catalogued and identified using as a comparison list the catalogue obtained from a spectrum of 153P 2002 Ikeya-Zhang taken on April 20 2002 1 2 One of our aims is also to compare between them these spectra looking for differences in the lines visible in the orders before and after the impact References 1 Cremonese G et al 2006 A A in press 2 Capria M T et al 2005 A A 442 1121-1126
