IC 1050 is a type Sbc[1] spiral galaxy located in constellation Boötes.[2][3] It is located 491 million light-years from the Solar System[4] and has an approximate diameter of 130,000 light-years.[5] IC 1050 was discovered by Stephane Javelle on June 3, 1892.[5]
Supernovae[edit]
Two supernovae have been discovered in IC 1050: SN 2020jgs and SN 2021och.
SN 2020jgs
SN 2020jgs[6] was discovered via r-ZTF filters from a Palomar 1.2m Oschin telescope on May 4, 2020, by K. De from Caltech[7] on the behalf of Zwicky Transient Facility.[8] SN 2020jgs had a magnitude of 18.3 and classified as a Type Ia supernova.[9][10]
SN 2021och
SN 2021och was discovered via r-ZTF filters taken also from a Palomar 1.2m Oschin telescope on June 1, 2021.[11] The supernova was reported by A. Munoz-Arancibia, F. Forster, F.E. Bauer, G. Pignata, L. Hernandez-Garcia, L. Galbany, E. Camacho, J. Silva-Farfan, and other astronomers,[12] on the behalf of ALeRCE broker (Automatic Learning for the Rapid Classification of Events).[13] SN 2021och had a magnitude of 18.8[12] and located at redshift 0.032.[14] It was confirmed to be Type Ia[12] which probably resulted from the explosion of a white dwarf.[15]
