Contribution

It presents a new convex shape and spin-axis model of asteroid (2501) Lohja based on combined dense photometric observations over multiple years.

Findings

Sidereal rotation period of 3.80835 hours

Prograde rotation sense identified

Main ratios of the asteroid's ellipsoidal shape

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.
