Best method
Start with the brightest nearby objects, then compare Full Moon with the AR overlay.

Full Moon Guide: When and Where to Look
A full moon happens when the Moon is opposite the Sun in the sky, making the lunar disk appear fully illuminated from Earth.
Quick facts
Use these cues first, then confirm the pattern in the AR viewer.
Location matters
Altitude and direction change with latitude, longitude, date, and time.
Alignment tip
If the phone compass drifts, adjust the heading controls until a known star pattern lines up.
Why timing matters
The most dramatic full moon views often happen near moonrise or moonset, when the Moon is low and foreground objects make its apparent size easier to appreciate.
What the sky looks like
A bright full moon washes out many faint stars and deep-sky objects. It is better for casual moon viewing than for seeing the Milky Way or faint constellations.
Use AR for direction
Use the AR viewer to orient yourself before moonrise and compare the Moon’s direction with nearby stars or constellations.
Frequently asked questions
Short answers for common skywatching questions before opening the AR viewer.
Can I find Full Moon from a city?
Often yes if the key stars or object are bright enough, but haze, buildings, and light pollution can hide fainter details.
Why can the AR overlay be slightly offset?
Mobile compass readings can drift near metal, cases, cars, and buildings. Use a known bright object to tune the heading offset.
Does my location change the result?
Yes. The same object can be high, low, or below the horizon depending on your location and the current time.
