Bright Supernovae - 2017

This data comes from IAU Circulars and occasionally more data will be provided on IAU's Astronomical Headlines page. An archive of the 2017 updates to this page is available.

This is a partial list of the SN discovered in 2017. Since 2017 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   Since that is no longer applicable, I am sorting this archive by "first observed" date, which I have listed as the discovery date.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.
