Moon Where? does more than list ephemeris values. For a selected time and place it explains whether the Moon is above the horizon, which compass direction to face, how high to look and whether clouds are likely to interfere.
First-use checklist
Confirm the observing place and calculation time.
Check whether altitude is above 0°.
Match azimuth to the compass and inspect the local skyline.
Compare hourly cloud and precipitation forecasts.
Recalibrate the phone compass if the direction drifts.
Camera permission is optional; numerical positions, times and guides remain available without it.
Sources, responsibility and limitations
Lunar calculations use SunCalc in the browser. Cloud and precipitation forecasts come from Open-Meteo after coordinates are rounded to two decimal places. Terrain, buildings, haze and compass calibration can make a real observation differ from the estimate.

From a Moon time to a real observing plan
Confirm the place and timezone shown above. City-center results differ from your exact observing spot.
Read altitude and azimuth together: a positive altitude means above the calculated horizon, not a clear line of sight.
Compare your goal with the hourly path, weather and skyline. No forecast means conditions are unknown.
