Abstract This paper is devoted to the discovery of 37 asteroids at the Baldone Astrophysical Observatory (MPC 069) from 2015 to 2018, and one of dynamically interesting Mars-crosser (MC) observed at the Baldone Astrophysical Observatory, namely 2008 LX16. In Baldone Observatory, was independently discovered the Near-Earth Object 2018 GE3 on the image of 13 April 2018. Also, the NEO 2006 VB14 was observed doing its astrometry and photometry. Moreover, we observed asteroids 1986 DA and 2014 LJ1. We computed orbits and analyzed the orbital evolution of these asteroids. 566 positions and photometric observations of NEO objects 345705 (2006 VB14) and 6178 (1986 DA) were obtained with Baldone Schmidt telescope in 2018 and 2019. We detected their rotation period and other physical characteristics. Also, a Fourier transform was applied to determine the rotation period of asteroid 6178 (1986 DA). Value (3.12 ± 0.02)h was obtained. Our observations confirm the previously obtained rotation periodP=3.25hfor2006VB14.

2015-2018年在巴尔登天文台发现的小行星的观测数据和轨道

摘要 本文致力于2015年至2018年在Baldone天体物理天文台(MPC 069)发现的37颗小行星,以及Baldone天体物理天文台观测到的动态有趣的火星穿越者(MC)之一,即2008 LX16。在 Baldone 天文台,在 2018 年 4 月 13 日的图像上独立发现了近地天体 2018 GE3。此外,还观察到 NEO 2006 VB14 进行天体测量和光度测量。此外,我们还观测到了小行星 1986 DA 和 2014 LJ1。我们计算了轨道并分析了这些小行星的轨道演化。2018 年和 2019 年使用 Baldone Schmidt 望远镜获得了近地天体 345705(2006 VB14)和 6178(1986 DA)的 566 个位置和光度观测。我们检测了它们的自转周期和其他物理特征。还,应用傅里叶变换来确定小行星 6178 (1986 DA) 的自转周期。获得值 (3.12 ± 0.02)h。我们的观察证实了先前获得的旋转周期 P=3.25hfor2006VB14。
