Extragalactic Novae

Extragalactic Novae - 2024

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 2024 updates to this page is available.

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
