First Quarter on . The illuminated surface of the moon is 57% and growing larger. The lunar cycle is 8 days young.
* The exact date and time of this First Quarter phase is on 1 May 2009 at 20:44 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 ∠20° of ♌ Leo tropical zodiac sector.
Next Full Moon is the Flower Moon of May 2009 after 6 days on 9 May 2009 at 04:01.
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 2.5% wider than solar disc. Moon and Sun apparent angular diameters are ∠1952" and ∠1903".
The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 115 of Meeus index or 1068 from Brown series.
The length of this lunation is 29 days, 8 hours and 48 minutes and it is 1 hour and 24 minutes longer than the upcoming lunation's length. The lengths of the following synodic months are going to decrease with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).
The length of the current synodic month is 3 hours and 56 minutes shorter than the mean synodic month length. It is 2 hours and 13 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 ∠311.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠332.7°.
4 days since point of perigee on 28 April 2009 at 06:26 in ♊ Gemini the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 11 days until the Moon reaches the point of next apogee on 14 May 2009 at 02:57 in ♑ Capricorn.
The Moon is 367 152 km (228 138 mi) away from Earth and getting further over the next 11 days until the point apogee when Earth-Moon distance is going to be 404 916 km (251 603 mi).
1 day after descending node on 1 May 2009 at 07:50 in ♌ Leo the Moon is positioned south of the ecliptic over the following 12 days until the lunar crosses the ecliptic again from South to North in ascending node on 15 May 2009 at 07:13 in ♒ Aquarius.
4 days since the last northern standstill on 28 April 2009 at 08:50 in ♊ Gemini when the Moon has reached North declination of ∠26.567° the lunar orbit is extending southward over the next 9 days to face maximum declination of ∠-26.486° at the point of next southern standstill on 11 May 2009 at 20:03 in ♐ Sagittarius.
14 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 6 days on 9 May 2009 at 04:01 in ♏ Scorpio 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.
