NGC 6627 is a barred spiral galaxy in the constellation of Hercules. Its velocity with respect to the cosmic microwave background is 5,146±9 km/s, which corresponds to a Hubble distance of 247.6 ± 17.3 Mly (75.90 ± 5.31 Mpc).[1] However, 25 non-redshift measurements give a much closer mean distance of 197.10 ± 15.05 Mly (60.432 ± 4.615 Mpc).[2] It was discovered by German astronomer Albert Marth on 13 July 1863.[3]

NGC 6627 is an active galaxy nucleus candidate, i.e. it has a compact region at the center of a galaxy that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.[4]

Supernovae

Three supernovae have been observed in NGC 6627:

  • SN 1998V (Type Ia, mag. 16) was discovered by British amateur astronomer Mark Armstrong on 10 March 1998.[5][6]
  • SN 2018evy (Type II, mag. 17.503) was discovered by ATLAS on 11 August 2018.[7]
  • SN 2021abkm (Type II, mag. 18.151) was discovered by ATLAS on 14 October 2021.[8]
