NGC 5406 is a barred spiral galaxy in the constellation of Canes Venatici. Its velocity with respect to the cosmic microwave background is 5,571±13 km/s, which corresponds to a Hubble distance of 268.0 ± 18.8 Mly (82.17 ± 5.76 Mpc).[1] However, seven non-redshift measurements give a much closer mean distance of 140.06 ± 34.21 Mly (42.943 ± 10.489 Mpc).[2] It was discovered by German-British astronomer William Herschel on 16 May 1787.[3][4]

NGC 5406 is a LINER galaxy, i.e. a galaxy whose nucleus has an emission spectrum characterized by broad lines of weakly ionized atoms.[5][6]

According to Abraham Mahtessian, NGC 5406 and NGC 5407 form a pair of galaxies.[7]

Supernovae

Two supernovae have been observed in NGC 5406:

  • SN 1977B (type unknown, mag. 14) was discovered by Hungarian Astronomer Miklós Lovas on 18 March 1977.[8][9]
  • PSN J14002117+3854517 (Type II, mag. 18.2) was discovered by Paolo Campaner and the Italian Supernovae Search Project (ISSP) on 18 February 2015.[10][11]
