Bright Supernovae - 2005

This data comes from IAU Circulars and occasionally more data will be provided on IAU's Astronomical Headlines page. An archive of the 2005 updates to this page is available.

This is a list of the supernovae discovered in 2005. For supernovae which are still visible, please look at the main page for the latest data.  

For more information, you can look at the following Supernova Catalogs:
• IAU List of Supernovae since 1885
• Mike Richmond's Supernova list

For the year 2005, 367 (a new record!) supernovae have been reported (249 last year).   80 in NGC and IC galaxies (66 last year), 149 got brighter than 18th Mag (126 last year). 17 extragalactic novae were also reported. The brightest supernova reported for the year was 2005df at mag 12.3, followed by 2005af at 12.5, and 2005cs at 13.5.  

Interesting events in 2005
• Both 2005en and 2005eo were found at almost the same time in UGC 4132.
• For the 3rd time, Robert Evans has discovered a supernova (2005df) in the very southern galaxy NGC 1559.
• 2005cs in M51 is a type II slightly reddened by dust.  
• For the first time this year, I have an image of EVERY supernova above magnitude 18.0.
