Much of this data comes from CBET Circulars and occasionally more data will be provided on IAU's Astronomical Headlines page. CBET now has an M31 novae page, M33 novae page, and an M81 novae page.   An archive of the updates to this page is available.

CBET has a naming convention now for novae in M31 (now extended to Novae in M33 and M81).   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.   Novae in the megellanic clouds are named with the year followed by a number.   Also, see W. Pietsch's M31 (apparent) optical nova catalogue Please note that I do not keep track of galactic novae.
