Seventeen middle-resolution optical spectraof comet 103Р/Hartley 2 were obtained on 26–28 October 2010 with the help of the 2-m Zeiss reflector andechelle-spectrograph of the High-mountain astronomical station of Institute of Astronomy of Russian Academy ofSciences and Main Astronomical Observatory of National Academy of Sciences of Ukraine at Peak Terskol. Thecomet was at heliocentric distance 1.06 A.U. and geocentric one 0.13 A.U. and had the integral magnitude equal tom1 =9.1m. We built the energy distribution in the spectra of comet 103P and made the detailed identification of thespectral emission lines in these spectra. Also in the spectra of comet we found out luminescent continuum in and determined some physical parameters of luminescent continuum. Short period comet 103Р/Hartley 2 of Jupiter’s cometfamily was the target of the space mission “EPOXI” in 2010.
