We confirm early findings by Romani et al. 2010 that the pulsar spectrum contains a thermal emission component. The component is best described by the blackbody model with the temperature $\\approx$ 60 eV and the emitting area radius $\\approx$ 17 $D_{\\rm kpc}$ km. The thermal emission likely originates from the entire surface of the cooling neutron star if the distance to the pulsar is $\\approx$ 0.8 kpc. The latter is suppor","authors_text":"A. Danilenko, A.
