2296 Kugultinov, provisional designation 1975 BA1, is an asteroid in the asteroid belt about 22 kilometers[lower-alpha 1] in diameter. It was discovered on January 18, 1975 by Russian astronomer Lyudmila Chernykh at the Crimean Astrophysical Observatory in Nauchnyj.[6] It orbits the Sun at a distance of 2.6–3.7 AU once every 5 years and 8 months (2,072 days). As it belongs to the Themis family of asteroids,[lower-alpha 1] the orbit is almost coplanar with the ecliptic plane, tilted by only 1¼ degree.[1]
It has a rotation period of 10 hours.[3] Photometric measurements of its light-curve in 2015 resulted in divergent time spans for the asteroid's synodic period of rotation. While one observation over a period of five days gave 8.4332±0.0224 hours[lower-alpha 2] a second observation over 13 nights (performed in the same time period) yielded a much larger period of 16.850±0.004 hours[lower-alpha 3] with an amplitude of 0.23 in magnitude.[4][5]
The asteroid was named in honor of David Nikitich Kugultinov (1922–2006), renowned Soviet poet and national poet of the Republic of Kalmykia (also see 2287 Kalmykia).[2]

- ↑ Photometric observations of main-belt asteroid 2296 Kugultinov were made over a period of five nights spanning 2015 March 27 to April 20. The measured rotation period is 8.4332 ± 0.0224 h.Bibcode: 2015MPBu...42Q.241H
- ↑ The minor planet 2296 Kugultinov was observed on 13 nights between 2015 March 13 and April 21. The analysis yielded a synodic period of rotation of P = 16.850 ± 0.004 h and amplitude of A = 0.23 mag. This result is in disagreement with a previously reported period of P = 10.41 h.Bibcode: 2015MPBu...42..284L
