IC 5145 is a type Sab spiral galaxy [1] located in the constellation Pegasus. [2] [3] It is located 356 million light-years from the Solar System [4] and was discovered by Edward Emerson Barnard, although the year he discovered it is unknown. [5]

The luminosity class of IC 5145 is I-II and it has a broad H II region. [4] Its dimensions measure 1.60 x 0.9 arcmin. [6]

Supernovae

Six supernovae have been discovered in IC 5145 so far: SN 2002dn, SN 2003hy, SN 2010iq, PSN J21542359+1509224, SN 2020pkj, and SN 2022lfa.

SN 2002dn

SN 2002dn [7] was discovered in IC 5145 by astronomer W. D. Li from University of California at Berkeley via unfiltered KAIT CCD images taken on June 15 and June 17, 2002. [8] It was located 8".8 west and 18".3 north of the nucleus. [9] A further inspection done by A. V. Filippenko, R. Chornock and R. J. Foley, using the Shane 3-m reflector at Lick Observatory confirmed SN 2002dn was a Type Ic supernova which resembled SN 1987m. [8] [7]

SN 2003hy

SN 2003hy [10] was discovered by British amateur astronomer, Tom Boles from Coddenham, England on September 14, through unfiltered CCD images using a 0.35-m reflector as part of the course done by U.K. Nova/Supernova Patrol. [11] Surprising, SN 2003hy was also discovered by another amateur astronomer, Mark Armstrong who saw it on the same unfiltered CCD images and via a 0.35m reflector. [11] It had a magnitude of 16.6 [10] and was located 5".5 west and 12".5 north of the nucleus. [12] The supernova was Type IIn. [10]

A 14-minute exposure of SN 2003hy taken on December 28, 2003, shows it is much dimmer than 19.4 magnitude, which the dimmest stars are magnitude 20. [13]

SN 2010iq

Lick Observatory Supernova Search discovered SN 2010iq on October 11, 2010. [14] It was reported by A. Narla, S. B. Cenko, W. Li and A. V. Filippenko from University of California, Berkeley through unfiltered CCD images. [15] It was located 2".8 east and 4".4 south of the nucleus with a magnitude of 18.2. [14] This supernova was Type Ic. [14]

PSN J21542359+1509224

PSN J21542359+1509224 was discovered on 13 May 2014 by Bin Wang and Xing Gao. [16] It was located 5".3 east and 0".9 south of the nucleus with a magnitude of 18.3. This supernova had an unknown type. [16]

SN 2020pkj

SN 2020pkj (type Ia, mag. 19.2) was discovered on 15 July 2020 by ZTF. [17]

SN 2022lfa

SN 2022lfa [18] was discovered on May 28, 2022, by Zwicky Transient Facility (ZTF) through Palomar 1.2m Oschin telescope on the behalf of K. De from Caltech. [19] On June 28, 2022, astronomers confirmed that SN 2022lfa is a Type Ic supernova via a spectrum obtained on MJD 59755.43 using the 3-m Shane telescope at Lick Observatory. [20]
