Welcome to the open supernova catalog! The goal of this catalog is to act as a centralized, open repository for supernova metadata, light curves, and spectra. The list of supernovae available here is scraped from various data repositories and individual publications. If you use this data, please reference the cited sources of that data. We’d also appreciate if you referenced the paper describing this catalog. Thanks!
The table below is generated from JSON files produced by AstroCats, which agglomerates the data for each supernova as a series of JSON files that all adhere to the same schema. The entirety of the data available for any supernova can be downloaded by clicking the 
icon in the Data column. If you would like to contribute data yourself, please visit our contribute page. If you are aware of a source of data that is already available either online or in the literature, please add the source of data to our to do list. If you spot any mistakes, please create a new issue on our GitHub issue tracking page, or contact us via e-mail.

Tips for searching:ย Individual column searches (the text boxes at the bottom of the table) support basic logical operators. 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 P. Adding an exclamation point to your query will negate the query, e.g. !ASASSN in the name column will return all events without ASASSN in its name. For numeric columns basic limits and ranges are supported; for instance, to search for events with redshifts less than 0.2, enter <0.2 into the zย column filter field at the bottom of the table. Our search syntax currently supports <, >, <=, >=, ranges (e.g. 0.2 – 0.4), and multiple simultaneous criteria (e.g. OR) when individual rules are comma separated (e.g. <0.2, 1.0 – 1.5).
