Previous main lunar phase is the Full Moon before 6 days on 7 July 2009 at 09:21.
Moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.
Lunar disc appears visually 3.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1830" and ∠1888".
Next Full Moon is the Sturgeon Moon of August 2009 after 23 days on 6 August 2009 at 00:55.
There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.
The Moon is 20 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 117 of Meeus index or 1070 from Brown series.
Length of current 117 lunation is 29 days, 7 hours and 1 minute. This is the year's shortest synodic month of 2009. It is 27 minutes shorter than next lunation 118 length.
Length of current synodic month is 5 hours and 44 minutes shorter than the mean length of synodic month, but it is still 25 minutes longer, compared to 21st century shortest.
This New Moon true anomaly is ∠349.4°. At beginning of next synodic month true anomaly will be ∠4.5°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).
5 days after point of apogee on 7 July 2009 at 21:39 in ♑ Capricorn. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 8 days, until it get to the point of next perigee on 21 July 2009 at 20:16 in ♋ Cancer.
Moon is 391 628 km (243 346 mi) away from Earth on this date. Moon moves closer next 8 days until perigee, when Earth-Moon distance will reach 357 465 km (222 118 mi).
4 days after its ascending node on 8 July 2009 at 15:24 in ♑ Capricorn, the Moon is following the northern part of its orbit for the next 8 days, until it will cross the ecliptic from North to South in descending node on 22 July 2009 at 03:47 in ♌ Leo.
4 days after beginning of current draconic month in ♑ Capricorn, the Moon is moving from the beginning to the first part of it.
8 days after previous South standstill on 5 July 2009 at 07:34 in ♐ Sagittarius, when Moon has reached southern declination of ∠-26.460°. Next 6 days the lunar orbit moves northward to face North declination of ∠26.477° in the next northern standstill on 19 July 2009 at 13:01 in ♊ Gemini.
After 8 days on 22 July 2009 at 02:35 in ♋ Cancer, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
