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 [9] [10]
1620 Geographos is a highly elongated, stony asteroid, near-Earth object and potentially hazardous asteroid of the Apollo group, with a mean diameter of approximately 2.5 km (1.6 mi). It was discovered on 14 September 1951, by astronomers Albert George Wilson and Rudolph Minkowski at the Palomar Observatory in California, United States. The asteroid was named in honor of the National Geographic Society.
719 Albert, provisional designation 1911 MT, is a stony asteroid, approximately 2.5 kilometers in diameter, classified as a near-Earth object of the Amor group of asteroids. It was discovered by Austrian astronomer Johann Palisa at the Vienna Observatory on 3 October 1911, and subsequently a lost minor planet for 89 years. The asteroid was named in memory of Albert Salomon Anselm von Rothschild, an Austrian philanthropist and banker. Albert was the second Amor asteroid discovered, the first being 433 Eros.
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.
Erna, provisional designation 1895 CB, is a dark asteroid of the background population in the outer regions of the asteroid belt, approximately 46 kilometers in diameter. It was discovered by French astronomer Auguste Charlois at Nice Observatory on 22 August 1895. The asteroid was presumably named after Erna Bidschof, the granddaughter of Johann Palisa.
925 Alphonsina, provisional designation 1920 GM, is a stony Hansian asteroid from the central region of the asteroid belt, approximately 58 kilometers in diameter.

It was named for the Spanish Kings Alfonso X and Alfonso XIII.
986 Amelia is a large background asteroid from the outer regions of the asteroid belt, approximately 50 kilometers in diameter. It was discovered on 19 October 1922, by Spanish astronomer Josep Comas i Solà at the Fabra Observatory in Barcelona. The L/D-type asteroid has a rotation period of 9.5 hours. It was named after the discoverer's wife, Amelia Solà.
1025 Riema, provisional designation 1923 NX, is a bright Hungaria asteroid from the innermost regions of the asteroid belt, approximately 5 kilometers in diameter. It was discovered on 12 August 1923, by German astronomer Karl Reinmuth at the Heidelberg Observatory in southwest Germany. The asteroid was named after ARI astronomer Johannes Riem.
2006 Polonskaya (provisional designation: 1973 SB3) is a stony Flora asteroid and asynchronous binary system from the inner regions of the asteroid belt, approximately 5 kilometers (3.1 miles) in diameter. It was discovered on 22 September 1973, by Soviet astronomer Nikolai Chernykh at the Crimean Astrophysical Observatory in Nauchnij, on the Crimean peninsula, and later named after Ukrainian astronomer Elena Kazimirtchak-Polonskaïa. Its one-kilometer-sized satellite was discovered by an international collaboration of astronomers in November 2005.
1111 Reinmuthia is a very elongated asteroid from the background population, located in the outer region of the asteroid belt. It was discovered on 11 February 1927, by German astronomer Karl Reinmuth at the Heidelberg Observatory in southwest Germany. The F-type asteroid (FX) has a short rotation period of 4.02 hours and measures approximately 40 kilometers in diameter. It was later named in honor of Karl Reinmuth, the discoverer himself.
1338 Duponta, provisional designation 1934 XA, is a stony Florian asteroid and synchronous binary system from the inner regions of the asteroid belt, approximately 7.8 kilometers in diameter.
1188 Gothlandia, provisional designation 1930 SB, is a stony Florian asteroid from the inner regions of the asteroid belt, approximately 12 kilometers in diameter. Discovered by astronomer Josep Comas i Solà at the Fabra Observatory in 1930, the asteroid was later named after the ancient name of the Spanish autonomous community of Catalonia.
5905 Johnson, provisional designation 1989 CJ1, is a Hungaria asteroid and synchronous binary system from the innermost regions of the asteroid belt, approximately 4 kilometers (2.5 miles) in diameter. It was discovered on 11 February 1989, by American astronomer Eleanor Helin at Palomar Observatory in California, United States.

3868 Mendoza, provisional designation 4575 P-L is a stony Vestian asteroid and binary system from the inner regions of the asteroid belt, approximately 9 kilometers in diameter. It was discovered on 24 September 1960, by astronomers Cornelis Johannes van Houten, Ingrid van Houten-Groeneveld and Tom Gehrels at Palomar Observatory.
1376 Michelle, provisional designation 1935 UH, is a stony Florian asteroid from the inner regions of the asteroid belt, approximately 8 kilometers in diameter.

The asteroid was discovered on 10 January 1997 by the Spacewatch survey at Kitt Peak National Observatory near Tucson, Arizona
Institute of Astronomy of Kharkiv National University, or Kharkiv Astronomical Observatory — is a scientific institution at Kharkiv University. The institution was founded in 1808 as the astronomy laboratory of the university, and in 1888, mainly due to the efforts of Gregory Levitsky, a fully equipped observatory in a separate house was created.
(458271) 2010 UM26 and 2010 RN221 are a pair of sub-kilometer-sized asteroids that have extremely similar orbits in the main asteroid belt. These two asteroids are thought to have dissociated from a binary system sometime in the 2000s, which would make them one of the youngest asteroid pairs known. The largest member of this pair, (458271) 2010 UM26 (or simply 2010 UM26), is about 760 m (2,490 ft) in diameter and was discovered on 10 November 2006 by the Spacewatch survey at Kitt Peak Observatory. The smaller member, 2010 RN221, is about 350 m (1,150 ft) in diameter and was discovered on 11 September 2010 by the Mount Lemmon Survey at Mount Lemmon Observatory. It was not until February 2022 that astronomers began to recognize the similar orbits of these asteroids.
