## Actions

### Get astronomy forecast

Get 72 hours of stargazing conditions in 3-hour steps: cloud cover, astronomical seeing (how steady the air is), sky transparency, humidity and wind, to plan a night of observing or astrophotography. No API key required.

**Inputs**

- Latitude (`latitude`, number, required): The place's latitude in degrees, -90 to 90 (north is positive). From -90 to 90.
- Longitude (`longitude`, number, required): The place's longitude in degrees, -180 to 180 (east is positive). From -180 to 180.

**Outputs**

- `attribution` (text): The credit line to show with the forecast.
- `count` (number): How many entries are in 'periods'.
- `latitude` (number): The latitude the forecast is for.
- `longitude` (number): The longitude the forecast is for.
- `model_run` (text): When the weather model run behind this forecast started, in UTC (ISO 8601), e.g. '2026-10-16T12:00:00Z'. 7Timer! updates four times a day.
- `periods` (list): Observing conditions in 3-hour steps, 72 hours ahead.
- `product` (text): The 7Timer! product that was asked for, e.g. 'civil'.
- `summary` (text): One line describing the forecast's first entry.
