Abstract

New orbit for C/2014 W10 PANSTARRS is obtained. High original eccentricity of e = 1.65 might suggest an interstellar origin of this comet. The probable reasons for missing this possible important event is discussed and a call for searching potential additional observations in various archives is proposed.
