Bright Supernovae - 2010.

Bright Supernovae - 2010

This data comes from IAU Circulars and occasionally more data will be provided on IAU's Astronomical Headlines page. An archive of the 2010 updates to this page is available.

This is a list of the SN discovered in 2010. Please look at the main page for the latest data. 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:

IAU List of Supernovae since 1885

Mike Richmond's Supernova list

For the year 2010, 586 supernovae (340 CBAT, 246 other sources) have been reported (513 last year). The brightest SN of the year is 2010ih (Mag 12.8) followed by 2010jl (Mag 12.9), 2010ev (Mag 13.7) and 2010hg (Mag 13.9).

Statistics in 2010

The first 2010O assigned turned out to be a foreground star, so I renamed that entry 2010O_old. 2010db also turned out to be a high proper motion star.
The following objects turned out to be LBV (Luminout Blue Variables, like Eta Carini) 2010dn and 2010da (second one in NGC 300)
Our second most prolific galaxy, NGC 3690, had two supernovae, 2010O and 2010P (which was only visible in IR)
VVV-WIT-01 just might be a very dim supernova in the Milky Way, from data published in 2012.
