Photometry of comet C/2011 L4 (PANSTARRS) at 4.4 - 4.2 AU heliocentric distances

Abstract

We present an analysis of the photometric data of comet C/2011 L4 (PANSTARRS) observed at heliocentric distance of 4.4 - 4.2 AU. The comet C/2011 L4 (PANSTARRS) shows one significant activity, despite of its quite large heliocentric distance. The color indexes, dust mass-loss rates and radius of the comet are measured.
