Bright Supernovae - 2020

This data comes mostly from TNS, and occasionally more data comes from IAUC TOCP and ATEL circulars.   An archive of the 2020 updates to this page is available.

This is a partial list of the SN discovered in 2020. 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   Since that is no longer applicable, I am sorting this archive by "first observed" date, which I have listed as the discovery date.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.
