Lightcurve Analysis of Two Near-Earth Asteroids: 2010 VB1 and 2014 JO25
Abstract
CCD photometric observations were made of the near- Earth asteroids (NEAs) 2010 VB1 in 2017 June and 2014 JO25 in 2017 April. The lightcurves for both asteroids showed significant day-to-day evolution due to changing viewing aspects. For 2010 VB1, the average synodic period was 0.18919 ± 0.0002 h while the amplitude decreased in near step with the phase angle, going from 0.99 mag at 54° to 0.61 mag at 27°. For 2014 JO25, the average synodic period was 4.60 ± 0.04 h. Its amplitude ranged from 0.39 to 0.14 mag.
