Abstract

We present a preliminary results of study of one middle-resolution optical spectrum of comet C/2002 T7 (LINEAR) obtained by V.Chavushyan on Jan. 28, 2004 with the help of the 2.12-m reflector of the Guillermo Haro Astrophysical Observatory. The energy distributions in the nucleus and coma of the comet are built, detailed identification of the spectral emission lines in the nucleus and coma spectra was made, physical parameters of gas of cometary atmosphere are calculated.
