NGC4411B (also known as UGC7546) is a barred spiral galaxy in the constellation of Virgo. Its velocity with respect to the cosmic microwave background is , which corresponds to a Hubble distance of . Two non-redshift measurements give a similar distance of . It was discovered by French astronomer Guillaume Bigourdan on 25 April 1895. There was a longstanding confusion of identification between this galaxy and the neighboring spiral galaxy NGC 4411. Therefore, this galaxy, despite its common name, was not a part of the original New General Catalogue.
NGC 4411B and NGC 4411 form a pair of galaxies, referred to as KPG 336. Both galaxies are members of the Virgo Cluster.
NGC4411B is a Seyfert II 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 4411B. SN1992ad (TypeII, mag. 13.5) was discovered by Robert Evans on 1 July 1992. SN2021smj (TypeIa, mag. 17.025) was discovered by ATLAS on 8 July 2021.
