Scientific data health
Operator view of scientific-data health: coverage, freshness, provenance completeness, conflicts, derived values and provider status — every number computed from the live registries and committed snapshots. As of 2026-10-25.

Live external providers
The operational feeds AsteriaStar fetches from at request time — NOAA SWPC and NASA CCMC DONKI. Their health cannot be read from a stored history because none is kept: no provider response is written to the repository. The detail page therefore probes them as it renders and reports what the request actually did. Live provider health →
Quality
Every figure on this page is computed from the live provenance registry and committed snapshots — no hard-coded totals. JSON API: /api/v0/authority/data-health.
