IC 2759 is a small type E elliptical galaxy located in the constellation of Leo.[1][2][3] It is located 350 million light-years away from the Solar System[4] and was discovered on April 24, 1897, by Guillaume Bigourdan.[5] Sometimes IC 2759 is confused with the spiral galaxy, PGC 34882 which is located south of the galaxy.[6][7]

Supernova

One supernova has been discovered in IC 2759 so far: SN 2020lyo.

SN 2020lyo

SN 2020lyo[8] was discovered in IC 2759 by astronomer, Dr. David Bersier[9] on 8 June 2020 from All Sky Automated Survey for SuperNovae (ASAS-SN).[10] via a Liverpool Telescope.[9] It was 0".5 west and 0".0 south of the nucleus and located at redshift of 0.027.[10] The supernova was Type Ia.[8]

Hickson 51

The seven galaxies of Hickson Compact Group 51

IC 2759 is a member of Hickson 51.[11][12] It was one of the galaxies observed by Paul Hickson, when he published his article in 1982.[13] The other galaxies in Hickson 51, are NGC 3651, PGC 34882, NGC 3653, PGC 34907, PGC 34899 or NGC 3651 NED02 and PGC 34901.[14] IC 2759 in this case, is listed as HCG 51E.[2]
