Bright Supernovae - 2020
This data comes from
IAU Circulars
and occasionally more data will be provided on
IAU 's
Astronomical Headlines page.
An archive of the 2020 updates
to this page is available.
This is a partial list of the SN discovered in 2020.
Since 2020 is still ongoing, please look at the
main page for the latest data.
In previous years I tried to keep the yearly archive alphabetically sorted
by CBAT supernova name.
Since that is no longer applicable, I am sorting this archive by
"first observed" date, which I have listed as the discovery date.
Note that Extra galactic Novae have been moved to a special
Extra galactic novae page .
Mistakes (Galactic variables, asteroids, unconfirmed, etc) are in the
boneyard .
I also maintain an archive of the
updates .
