NGC 4219 is a spiral galaxy in the constellation of Centaurus. Its velocity with respect to the cosmic microwave background is , which corresponds to a Hubble distance of . However, 16 non-redshift measurements give a closer mean distance of . It was discovered by British astronomer John Herschel on 3 June 1834.
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.
Supernovae Two supernovae have been observed in NGC 4219: SN 2011am (TypeIb, mag. 17.4) was discovered by Australian amateur astronomer Stuart Parker on 27 February 2011. SN 2011hp (TypeIc, mag. 15.7) was discovered by South African amateur astronomer on 3 November 2011.
