Chuhuiv Observational Station (or Chuguev Observational Station) of the Institute of Astronomy of Kharkiv National University is an astronomical observatory founded in the early 1960s near the village of Ivanovka, Chuhuiv Raion, Kharkiv Oblast, Ukraine. In 2022 the observational station was occupied and severely plundered by Russian soldiers, who during 6 months of occupation stole or damaged most of the scientific equipment. [2] [3]

The founder of the observatory was Nikolai P. Barabashov. [4] [5] The main instrument of the observatory is 70-cm reflector AZT-8. [6] The observational station hosted one of the first coherent optics processors used to reduce astronomical observations. [7] The main topics of the observations conducted on the observational station are photometric observations of asteroids and monitoring of space debris. In particular, the observations conducted here significantly contributed to the introduction of H-G1-G2 asteroid magnitude system [8] and to the discovery of the YORP effect for several asteroids.

The Yarkovsky–O'Keefe–Radzievskii–Paddack effect, or YORP effect for short, changes the rotation state of a small astronomical body – that is, the body's spin rate and the obliquity of its pole(s) – due to the scattering of solar radiation off its surface and the emission of its own thermal radiation.
