Sun & moon
Sunrise, sunset, solar noon, day length, civil to astronomical twilight, moon phase, and where sun and moon are right now, from your station location.
The Astronomy tab is computed from your station's coordinates, with no external service and nothing to configure. It needs only that your station has a latitude and longitude. Connecting WeatherLink or a vendor cloud discovers them automatically; for pushed hardware you enter them once on the Connection page, in the station card under the upload URL.
Sun
- Sunrise, sunset and solar noon, with a progress bar through the day.
- Day length, and how much longer or shorter today is than yesterday: a few seconds around the solstices, over four minutes a day near the equinoxes.
- Civil, nautical and astronomical twilight, each as a dawn-to-dusk range.
- Azimuth and altitude right now: which compass bearing the sun is on and how high above the horizon.
- The next equinox and the next solstice, in the order they arrive.
Moon
- Phase, with its illuminated fraction and a matching symbol.
- Moonrise, moonset and transit, transit being the moment it crosses your meridian, its highest point of the night.
- Azimuth and altitude right now.
- Distance, the number behind a "supermoon".
- The next new moon, first quarter, full moon and last quarter, soonest first.
You can hide the moon panel under Panels → Wind & sky detail, leaving the sun on its own.
About the precision
Equinoxes and solstices are shown with a time because the calculation behind them is good to a few minutes. Moon phases are shown as dates only: the lunar model behind them is good to a couple of hours, and printing a clock time next to that would be false precision. A paper almanac gives you the date for the same reason.
Polar latitudes
At high latitudes the sun does not always rise or set. Days without a sunrise or sunset show no time and no day length rather than an invented one; the phase of the sky (daytime, civil, nautical or astronomical twilight, night) is still correct, because it is read from the sun's actual altitude.
What is coming up
The Astronomy tab describes the sky today. Its companion, the Sky events tab, lists what is coming: the next eclipse, meteor shower, planet at its best and supermoon visible from your station.

Forecast
A Forecast tab with the next 24 hours and 7 days for your station location from Open-Meteo, plus the short-range outlook your own barometer implies.
Sky events
A tab listing what is coming up in the sky over your station: eclipses, meteor showers, planets at their best, supermoons, equinoxes and solstices, filtered to what is visible from your coordinates.
