Sky weather · not the natal sitting
What is up tonight
Naked-eye planets after sunset, the Moon, and when twilight fades — for your place. This is sky weather, not the minute you were born. That sitting is the seven chapters.

Tonight above you
Pick a location above to compute tonight's sky.
How honest is this?
The planet positions and the Moon's phase are computed from real astronomy (VSOP87 planetary theory and ELP2000 lunar theory). The sunset, twilight, and altitude figures are good approximations: they assume a flat, unobstructed horizon at sea level and do not account for your local terrain, buildings, atmospheric refraction beyond a standard value, light pollution, or weather. Treat the minute marks as “about” and the visibility as “should be findable, sky permitting.” All times shown are in your local time zone.

- Your coordinates are processed locally and never transmitted to us.
- City search sends only the place name to Open-Meteo — never your exact position or the date.
- Geolocation is only used if you tap “Use my location” — coordinates go to Open-Meteo for timezone lookup only.
- No login, no account, no cookies required to see tonight's sky.
