Waning Gibbous
Illumination: 99-51%|Phase angle: ~225°
After the full moon, the illuminated area begins to shrink. 'Waning' means decreasing. The Moon now rises after sunset and is prominent in the late night and early morning sky. More than half of the surface remains lit during this phase.
Orbital Geometry
Past full moon, the illuminated portion begins to shrink from the right side (Northern Hemisphere). The angle between Sun, Earth, and Moon is roughly 225°.
Visibility & Observation
Rises after sunset and is prominent in the late-night and early-morning sky. Still bright enough to significantly affect nighttime observations.
Tidal Effects
Tidal range decreases from the spring tide peak as the Moon moves away from opposition, heading toward neap tides.
