Previous main lunar phase is the First Quarter before 2 days on 28 July 2009 at 22:00.
Moon rises in the afternoon and sets after midnight to early morning. It is visible to the southeast in early evening and it is up for most of the night.
Moon is passing about ∠8° of ♐ Sagittarius tropical zodiac sector.
Lunar disc appears visually 5.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1797" and ∠1890".
Next Full Moon is the Sturgeon Moon of August 2009 after 5 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 10 days young. Earth's natural satellite is moving from the first to the middle part of current synodic month. This is lunation 118 of Meeus index or 1071 from Brown series.
Length of current 118 lunation is 29 days, 7 hours and 27 minutes. It is 1 hour and 16 minutes shorter than next lunation 119 length.
Length of current synodic month is 5 hours and 17 minutes shorter than the mean length of synodic month, but it is still 52 minutes longer, compared to 21st century shortest.
This New Moon true anomaly is ∠4.5°. At beginning of next synodic month true anomaly will be ∠20.3°. 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°).
9 days after point of perigee on 21 July 2009 at 20:16 in ♋ Cancer. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 3 days, until it get to the point of next apogee on 4 August 2009 at 00:42 in ♑ Capricorn.
Moon is 398 897 km (247 863 mi) away from Earth on this date. Moon moves farther next 3 days until apogee, when Earth-Moon distance will reach 406 027 km (252 293 mi).
9 days after its descending node on 22 July 2009 at 03:47 in ♌ Leo, the Moon is following the southern part of its orbit for the next 4 days, until it will cross the ecliptic from South to North in ascending node on 4 August 2009 at 21:42 in ♑ Capricorn.
22 days after beginning of current draconic month in ♑ Capricorn, the Moon is moving from the second to the final part of it.
11 days after previous North standstill on 19 July 2009 at 13:01 in ♊ Gemini, when Moon has reached northern declination of ∠26.477°. Next day the lunar orbit moves southward to face South declination of ∠-26.478° in the next southern standstill on 1 August 2009 at 13:28 in ♐ Sagittarius.
After 5 days on 6 August 2009 at 00:55 in ♒ Aquarius, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
