List of Recent Supernovae

This page gives details on supernovae that have occurred since the start of 2015 . All coordinates given in the table below are J2000.0 positions. Date refers to the date of discovery, Mag. to the magnitude at discovery and Offset to the offset from the nucleus of the host galaxy as reported at time of discovery. Disc. Ref. is the reference to the discovery report, Posn. Ref. is the source of the accurate position and Type is the supernova's type (as reported at or near the time of discovery). Note that the preferred hierarchy for host-galaxy catalogue designations is M/NGC/IC, UGC, MCG; all other catalogues are considered "Anon" below.

Links are provided to the references, but access to recent circulars requires a subscription.
