The spectra and images obtained through broadband BVR filters for Jupiterfamaly comet P/2011 P1 were analyzed. We observed the comet on November 24,2011, when its heliocentric distance was 5.43 AU. Two dimensional long slitspectra and photometric images were obtained using the focal reducer SCORPIOattached to the prime focus of the 6-m telescope BTA (SAO RAS, Russia). Thespectra cover the wavelength range of 4200-7000 {\AA}. No emissions of C2 andCO+, which are expected in this wavelength region, were detected above 3 sigmalevel. An upper limit in gas production rate of C2 is expected to be 1.1*10^24mol*s^-1. The continuum shows a reddening effect with the normalized gradientof reflectivity along dispersion of 5.1% per 1000 {\AA}. The color indices(B-V)=0.89 and (V-R) = 0.42 for the nucleus region or (B-V)=0.68 and (V-R)=0.39for the coma region, which are derived from the photometric data, also evidencethat the color of the cometary nucleus and dust are redder with respect to theSun. The dust coma like a spiral galaxy adge on was fitted using a Monte Carlomodel.
