Shape model of the asteroid (2501) Lohja from long-term photometric observations

Abstract

We present lightcurves, shapes, and a 3D convex spin-axis model for the main-belt asteroid (2501) Lohja. The models were obtained with the lightcurve inversion process using combined dense photometric data from the apparitions between years 2006 and 2017. The analysis found a sidereal period of 3.80835\,hours, and a possible ecliptic pole solution (J2000.0), the prograde sense of rotation and main ratios of the ellipsoidal model.
