Extragalactic Novae - 2011

Much of this data comes from IAU Circulars and occasionally more data will be provided on IAU's Astronomical Headlines page. An archive of the 2011 updates to this page is available.

Due to the large number of Extragalactic Novae announced in 2003 I have decided to give these novae their own page. That way you don't need to hunt through the main page or the 2011 supernova archive to find them.   Announced Extragalactic Novae will have a link on the main page that points to this one.   Please note that I do not keep track of galactic novae.  

For current Novae, please see the main Extragalactic Novae page
