One email when the night is actually good

No daily newsletter. No “10 facts about the Moon.” We watch the forecast, and we only write when your city clears a real quality threshold.

What counts as “good”?

The alert threshold is a night score of 70 or better, weighed across the dark hours. That usually means mostly clear skies, a useful stretch of darkness, and limited Moon interference.

One email per good night, maximum.
No email when the forecast is marginal.
Confirmation and unsubscribe links in every message.
The score updates; a promising morning can fade by evening.
No weather-based alert when the forecast is old, incomplete or too coarse.
Delivery also depends on the site's sending allowance.

Prefer to check manually?

The city page is free and needs no account. The alert is just a convenience for nights you might otherwise miss.
