LIGHTCURVE ANALYSIS OF HILDA ASTEROIDS AT THE CENTER FOR SOLAR SYSTEM STUDIES: 2019 APRIL-JUNE.

Abstract

CCD photometric observations of seven Hilda asteroids were made at the Center for Solar System Studies (CS3) from 2019 April and June. Analysis of data for 1269 Rollandia and 3843 OISCA based on 2019 data led to review of our earlier results. For both objects, this resulted not in solving but deepening the mystery of the their true rotation periods.
