Lightcurve analysis of asteroid 15691 Maslov using NAO Rozhen observations and sparse data

Abstract

Abstract. Photometric observations of the asteroid 15691 Maslov, were performed with 2 m and 50/70 cm Schmidt telescopes at NAO Rozhen during the asteroid’s opposition in 2015 and 2022. Calculated colour indices suggest that 15691 Maslov belongs to the S spectral type. The composite lightcurve shows synodic rotation period of 7.8 ± 0.2h hours and amplitude of about 0.2 magnitudes. For calculation of the sidereal period with the lightcurve inversion technique we used our dense photometric data in combination with the sparse data from the AstDys2 database.
