Welcome to the open supernova catalog! The goal of this catalog is to act as a centralized, open repository for published supernova metadata, light curves, and spectra. The data on this page is scraped from various supernova data repositories, both defunct and active, and from individual papers that have published their data in machine-readable form. If you use this data, please reference the relevant works, and please reference this webpage. Thanks!
The table below is auto-updated from a GitHub repository which encodes the data on each event as a series of ASCII files in JSON format. If you would like to donate data, please visit our contribute page. If you spot any mistakes, please contact us.

Tips for searching:Â Individual column searches (the text boxes at the bottom of the table) for numeric columns support basic logical operators. For instance, to search for events with redshifts less than 0.2, enter ‘<0.2’ into the ‘z’Â column filter field at the bottom of the table. Syntax supports ‘<‘, ‘>’, ‘<=’, ‘>=’, ranges (e.g. ‘0.2 – 0.4’, except for the date fields), and multiple simultaneous criteria (e.g. “OR”) when individual rules are comma separated (e.g. ‘<0.2, 1.0 – 1.5’). For non-numeric columns, criteria can be comma separated to match multiple criteria (e.g. ‘NGC, UGC’ in the host field would return entries that match one or the other). Surrounding a selection in double quotes will enforce an exact match (e.g. “ia” will match ‘ia’ and not ‘ia-pec’).
