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 edit
This 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 edit
Two supernovas have been observed in NGC 7329: SN 2006bh and SN 2009iu.
SN 2006bh edit
This supernova was discovered on April 2, 2006, by South African amateur astronomer Berto Monard, in Pretoria.
SN 2009iu edit
This supernova 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.
