Here is tonight's Moon, taken under poor conditions. This image was taken about 12 hours before lunar apogee, and the interesting comparison here is with the image I took on October 31, which was within several hours of lunar perigee. Of additional interest is that the perigee that occurred on 31 October was the furthest perigee of the year, at just over 370,000km. Most lunar perigees occur at distances closer than this, with some falling under 360,000km. When a perigee occurs near a Quarter Moon (either first or last), that perigee is at a maximum distance due to the reduced eccentricity of the Moon's orbit when the line of apsides is perpendicular to the Sun-Earth line. Conversely, when a perigee occurs at a New or Full Moon, this corresponds with increased eccentricity of the orbit and the Earth-Moon distance is therefore at a minimum (these are "Supermoons").
