First Quarter on . The illuminated surface of the moon is 50% and growing larger. The lunar cycle is 7 days young.
* The exact date and time of this First Quarter phase is on 29 June 2009 at 11:28 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 about ∠8° of ♎ Libra tropical zodiac sector.
Next Full Moon is the Buck Moon of July 2009 after 7 days on 7 July 2009 at 09:21.
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 0.2% wider than solar disc. Moon and Sun apparent angular diameters are ∠1891" and ∠1887".
The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 117 of Meeus index or 1070 from Brown series.
The length of this lunation is 29 days, 7 hours and 1 minute and it is 27 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2009. 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 5 hours and 44 minutes shorter than the mean synodic month length. It is 25 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 ∠349.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠4.5°.
6 days since point of perigee on 23 June 2009 at 10:39 in ♋ Cancer the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 8 days until the Moon reaches the point of next apogee on 7 July 2009 at 21:39 in ♑ Capricorn.
The Moon is 379 096 km (235 559 mi) away from Earth and getting further over the next 8 days until the point apogee when Earth-Moon distance is going to be 406 233 km (252 421 mi).
4 days after descending node on 24 June 2009 at 17:24 in ♋ Cancer 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 8 July 2009 at 15:24 in ♑ Capricorn.
7 days since the last northern standstill on 22 June 2009 at 02:48 in ♊ Gemini when the Moon has reached North declination of ∠26.446° the lunar orbit is extending southward over the next 5 days to face maximum declination of ∠-26.460° at the point of next southern standstill on 5 July 2009 at 07:34 in ♐ Sagittarius.
18 days since the beginning of this draconic month in ♒ Aquarius the Moon is navigating from the second to the final part of the lunar cycle.
In 7 days on 7 July 2009 at 09:21 in ♑ Capricorn 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.
