Extragalactic Novae

Much of this data comes from IAU Circulars and occasionally more data will be provided on IAU's Astronomical Headlines page. CBET now has an M31 novae page An archive of the updates to this page is available.

CBET has a naming convention now for novae in M31.   This convention is YYYY-MMa, where YYYY is the year and MM is the 2-digit month of discovery, and 'a' is a lower-case letter (a, b, c, etc.) representing the order of discovery within that month.   All other novae on this page follow the naming convention for novae in the magellanic clouds.   This convention is simply the year followed by a number.

SNWeb is now collecting observations on extragalactic novae.   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 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.
