About Stargazr

One tap: is tonight good for stargazing, right where you are?

Stargazr answers the one question every backyard skywatcher actually asks — is it worth going outside tonight? Rather than a wall of raw numbers, it reads the sky for your exact location and gives you a single, honest go / no-go, then explains why.

What we check

• Clouds first — the cloud forecast for your precise spot, not a regional average. It's the factor that makes or breaks a night.
• The Moon — phase, how lit it is, and when it rises and sets. A bright Moon washes out faint stars, the Milky Way and meteors.
• Aurora — the live Kp index and OVATION model, read for your latitude, so you know if the northern or southern lights could reach you.
• The next meteor shower — its peak date, realistic rates, and an honest read on how much the Moon will spoil it.
• Real darkness — when astronomical twilight ends and true dark begins for you tonight.

Where our data comes from

We build on open, authoritative sources and credit them plainly:

• Cloud forecasts from MET Norway (CC BY 4.0).
• Aurora and space weather from the US NOAA Space Weather Prediction Center (public domain).
• Meteor-shower figures from the International Meteor Organization and the American Meteor Society.
• Moon and twilight computed locally with SunCalc; star positions from the Yale Bright Star Catalog (public domain), with the shared Astronomy Engine ephemeris.

Our approach to accuracy

We'd rather tell you the truth than oversell a night. The Moon-interference reads on our meteor-shower guides are computed, not guessed, and we say plainly when a year is a washout. The current tonight-conditions read is naked-eye accurate; an arcminute-accurate planetarium and telescope identifier are on the way. When we don't know, we say so.
