Moonlight Lab
The Moon has no light switch. The observation desk is open.
Predict. Reveal. Compare.
Six investigations, an observation board and free hints. Selected views, not equally spaced dates or today's sky.
Use the pictures only. Never look at the Sun through your eyes, a camera, binoculars or a telescope. No outdoor observation is required.

About the illustrated views
The disk pictures simplify one viewing orientation. Rotating a picture does not calculate a real observer's location. Crescent and gibbous drawings are examples, not fixed fractions for every observation. Earthshine, surface detail, precise timing and orbital geometry are omitted. A total lunar eclipse is shown symbolically, not as a prediction of its color or brightness.
