Celestial Tools

This theme collects public tools related to daylight, darkness, twilight, moonrise, moonset, and moon phase data for selected locations and dates.

Celestial reference data

The first tool in this theme will let you configure a location and time span, request celestial data, and inspect the calculated result directly in the browser.

It will follow the same location and period model already used by the Celestial source in the agent area, but as a public tool that can be run on demand.

Tool configuration

Use explicit UTC timestamps when you want a fixed celestial window that stays the same between runs.

Included celestial fields

Timestamp is always included automatically. Choose which additional celestial fields should be included in the result.
