  The polarimetric observations of asteroid 3200 Phaethon, the target of
international observation campaign, did not cover a proper phase angle interval
to provide estimating all the attributes of the asteroid polarization curve.
Based on present discrete observation data for Phaethon, its full polarimetric
curves in BVRI bandpasses were reproduced. The polarimetric properties of the
asteroid correspond to a notion on surface structure as thermally altered
regolith particles mixed with lager rock fragments like a coarse pebble.
