Abstract

The results of astrometric and photometric in <i>BVRI</i> bands observations of the potentially hazardous asteroids 2016LX48 and 2014JO25 carried out by the Zeiss-1000 and AZT-8 telescopes in the Sanglokh and Gissar observatories of the Institute of Astrophysics, Ac. Sci. of RT, at the period of their close approaches to the Earth in September 2016 and April 2017 have presented. The asteroid's coordinates and the orbit of 2014JO25 were determined as well as the apparent and absolute brightness in BVRI bands and color indexes were obtained. The light curves show that object's magnitudes have not been changed significantly during observations and the value of absolute magnitude of 2014JO25 corresponds to the ephemerid value. Estimations of the color-indexes, rotation periods and the 2014JO25 diameter by our observations are in well accordance with known data.

Keywords:

asteroid, astrometry, photometry, coordinates, orbit, light curve, color-index, diameter, rotation period
