NGC 4219 is a spiral galaxy in the constellation of Centaurus. Its velocity with respect to the cosmic microwave background is 2,277±20 km/s, which corresponds to a Hubble distance of 109.6 ± 7.7 Mly (33.59 ± 2.37 Mpc).[1] However, 16 non-redshift measurements give a closer mean distance of 72.00 ± 2.21 Mly (22.075 ± 0.679 Mpc).[2] It was discovered by British astronomer John Herschel on 3 June 1834.[3][4]

NGC 4219 is a Seyfert I galaxy, i.e. it has a quasar-like nucleus with very high surface brightnesses whose spectra reveal strong, high-ionisation emission lines, but unlike quasars, the host galaxy is clearly detectable.[5][6]

Supernovae

[edit]

Two supernovae have been observed in NGC 4219:

  • SN 2011am (Type Ib, mag. 17.4) was discovered by Australian amateur astronomer Stuart Parker on 27 February 2011.[7][8]
  • SN 2011hp (Type Ic, mag. 15.7) was discovered by South African amateur astronomer Berto Monard [it] on 3 November 2011.[9][10]
