SOURCE_ID: B1

SOURCE_NAME:
Open Supernova Catalog / AstroCats

SOURCE_REPOSITORY:
https://github.com/astrocatalogs/supernovae

SOURCE_TYPE:
Supernova metadata and photometry JSON catalog

STATUS:
sne.space web interface unavailable during access attempt.
GitHub repository remains usable as the source.

SOURCE_ROLE:
Index and metadata source for observed supernova light curves.

RELEVANT_REPOSITORY_NOTE:
The repository contains the primary JSON catalog file generated by AstroCats,
used to drive the web-based table formerly available at sne.space.
Because GitHub repositories are size-limited, individual event JSON files are
distributed across year-bucket repositories.
