  The spectra and images obtained through broadband BVR filters for Jupiter
famaly 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 slit
spectra and photometric images were obtained using the focal reducer SCORPIO
attached to the prime focus of the 6-m telescope BTA (SAO RAS, Russia). The
spectra cover the wavelength range of 4200-7000 {\AA}. No emissions of C2 and
CO+, which are expected in this wavelength region, were detected above 3 sigma
level. An upper limit in gas production rate of C2 is expected to be 1.1*10^24
mol*s^-1. The continuum shows a reddening effect with the normalized gradient
of 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)=0.39
for the coma region, which are derived from the photometric data, also evidence
that the color of the cometary nucleus and dust are redder with respect to the
Sun. The dust coma like a spiral galaxy adge on was fitted using a Monte Carlo
model.
