NGC 2535
Last updated
NGC 2535 is an unbarred spiral galaxy in the constellation Cancer. It is notable for its interaction with the companion galaxy NGC 2536, which has warped its disk and spiral arms, producing an elongated structure rich in bright, recently formed blue star clusters. The pair is listed together as Arp 82 in the Atlas of Peculiar Galaxies.

Background
NGC 2535 exhibits a weak inner ring structure around its nucleus. The gravitational interaction with NGC 2536 has warped the galaxy's disk and spiral arms, creating an elongated structure visible at ultraviolet wavelengths. This structure contains many bright, recently formed blue star clusters and enhanced star-forming regions around the galaxy center. The two galaxies are cataloged together as Arp 82 in the Atlas of Peculiar Galaxies, described as an example of a spiral galaxy with a high surface brightness companion.
One supernova, SN 1901A, has been observed in NGC 2535. It was first recorded on a photographic plate taken on 10 January 1901 by Karl Reinmuth, though the discovery was not made until 28 September 1923. The supernova's type remains unknown, and its apparent magnitude was 14.7.
