- Moonrise can take place after the moonset.
- Moonrise or moonset does not occur in the particular date and / or location. Both situations are pretty normal.
- The azimuth (0°-360°) is a horizontal angular measurement. The azimuth is the angle between the north vector and the projection of the star or moon down onto the horizon, e.g. if the moon is exactly on the east, then its azimuth is exactly 90°.
