Professional Observatory Planning Suite

Stable

The observing planners (tonight, visibility, target, Moon, planet, deep-sky, season, twilight, darkness, altitude, meridian-transit, equipment, astrophotography, session) built on the platform's real computed live-sky data and its observing equipment, sites and techniques, and the architecture-ready data integrations (weather, seeing, transparency, cloud cover, Bortle sky brightness) that await connected providers.

Live Provider Registry

Stable

The registry of real external scientific-data providers modelled with the honesty envelope — NOAA SWPC (space weather), NASA DONKI (solar activity), the Minor Planet Center and JPL/CNEOS (near-Earth objects), CelesTrak (orbital elements), and atmospheric conditions — each with its endpoint, licence, data kinds, and honest connection status.

Space-Weather Provider Status

Stable

The honest connection status of the space-weather and solar-activity providers (NOAA SWPC, NASA DONKI). No provider is connected in this deployment, so no solar-wind, Kp, flare, or CME value is served — every provider reports its real status and limitations.

Near-Earth-Object Provider Status

Stable

The honest connection status of the near-Earth-object providers (IAU Minor Planet Center, JPL/CNEOS). No provider is connected in this deployment, so no close-approach distance or date is served — every provider reports its real status and limitations.

Live-Data Limitations

Stable

The stated limitations of every live-data integration — which are architecture-ready, which await a licence-safe provider, and what would be required to connect each. A transparency record: no live value, timestamp, or provider response is ever fabricated.
