The luminosity class of NGC 7329 is II and it has a broad HI line. To date, 29 non-redshift measurements yield a distance of 44.662 ± 5.536 Mpc (~146 million ly),[3] which is within the Hubble distance range. Note that it is with the average value of independent measurements, when they exist, that the NASA/IPAC database calculates the diameter of a galaxy.[4]
Discovery
editThis galaxy was discovered in 1835 by the English astronomer John Herschel using a 47.5 cm (18.7 in) optical telescope that used a mirror as the light-gathering element.
Supernovae
editTwo supernovae have been observed in NGC 7329: SN 2006bh and SN 2009iu.
SN 2006bh
editThis supernova was discovered on April 2, 2006, by South African amateur astronomer Berto Monard, in Pretoria. It was cateogorized as type Ia with a magnitude of 14.8.[5]
SN 2009iu
editThis supernova, categorized as type Ib with a magnitude of 15.5, was discovered on September 1, 2009, by the CHASE (Chilean Automatic Supernova Search) project, a project searching for supernovae visible from astronomical observatories in the southern hemisphere.[6]
