ClearNights: Stargazing

ClearNights tells you exactly when the night sky is worth going outside for.

Most weather apps stop at "cloudy or clear." ClearNights goes further, scoring every upcoming hour for real stargazing: folding together darkness, cloud cover, atmospheric seeing (how steady the air is), and transparency (how clear it is) into a single 0–100 score. Plan the perfect night out with your eyes, binoculars, or a telescope.

WHAT YOU GET
• A per-hour stargazing score for tonight and the nights ahead
• Your best viewing window, surfaced at a glance
• The details that matter: seeing, transparency, cloud cover, limiting
magnitude, moon phase & altitude, and twilight
• Multiple saved locations: check home, a dark-sky site, or your next trip

CELESTIAL EVENTS
ClearNights also tells you what's happening overhead and whether you'll
actually be able to see it from where you are:
• Meteor showers, with peak timing and where to look
• Planetary conjunctions and bright-planet visibility
• Full moons and lunar eclipses
• Aurora (northern lights) potential from live space-weather data

SMART ALERTS
Set it once and get a single, well-timed heads-up when tonight is worth it.
Choose your minimum quality (Good, Great, Excellent), the hours you care about (no 4 a.m. alerts unless you want them), and which events to be told about.
