First Quarter on . The illuminated surface of the moon is 52% and growing larger. The lunar cycle is 7 days young.
* The exact date and time of this First Quarter phase is on 22 July 2007 at 06:29 UTC.
The moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Main moon phases of the following lunar cycle.
Moon is passing first ∠2° of ♏ Scorpio tropical zodiac sector.
Next Full Moon is the Buck Moon of July 2007 after 7 days on 30 July 2007 at 00:48.
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.
Lunar disc appears visually 6.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1889".
The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 93 of Meeus index or 1046 from Brown series.
The length of this lunation is 29 days, 10 hours and 59 minutes and it is 2 hours and 43 minutes shorter than the upcoming lunation's length. The lengths of the following synodic months are going to increase with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).
The length of the current synodic month is 1 hour and 45 minutes shorter than the mean synodic month length. It is 4 hours and 24 minutes longer compared to 21st century's shortest synodic month length.
The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠64.2° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠97.3°.
Moon is at apogee at 08:43 about 12 days since last perigee on 9 July 2007 at 21:38 in ♉ Taurus the lunar orbit is going to narrow while the Moon is moving towards the Earth over the upcoming 12 days until point of next perigee on 3 August 2007 at 23:52 in ♈ Aries.
This apogee Moon is 404 152 km (251 128 mi) away from Earth. This is the year's closest apogee of 2007. It is 1 256 km further than the mean apogee distance, but it is still 101 km closer than the farthest apogee of 21st century.
4 days after descending node on 18 July 2007 at 00:18 in ♍ Virgo the Moon is positioned south of the ecliptic over the following 9 days until the lunar crosses the ecliptic again from South to North in ascending node on 1 August 2007 at 06:03 in ♓ Pisces.
9 days since the last northern standstill on 12 July 2007 at 16:38 in ♊ Gemini when the Moon has reached North declination of ∠28.251° the lunar orbit is extending southward over the next 4 days to face maximum declination of ∠-28.300° at the point of next southern standstill on 26 July 2007 at 23:22 in ♐ Sagittarius.
17 days since the beginning of this draconic month in ♓ Pisces the Moon is navigating from the second to the final part of the lunar cycle.
In 7 days on 30 July 2007 at 00:48 in ♒ Aquarius the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
