We analyze observations by the Planetary Fourier Spectrometer (PFS) onboard Mars Express performed between October 13th and October 21st 2014 to search for spectral signatures of the comet and to investigate possible effects of its passage on the suspended dust and ice content in the Martian atmosphere.ELETTRONICOenConference abstracthttps://www.epsc2017.eu/information/general_information.html2017EPSC...11..749GFIS/05 - ASTRONOMIA E ASTROFISICA
