Bright Supernovae - 2004

This data comes from IAU Circulars and occasionally more data will be provided on IAU's Astronomical Headlines page. An archive of the 2004 updates to this page is available.

This is a archive of the supernovae discovered in 2012.   For supernovae that are still visible, please look at the main page.   Please look in the Archive page for a complete list.   Note that Extra galactic Novae have been moved to a special Extra galactic novae page.   For more information, you can look at the following Supernova Catalogs:
