FEBRUARY
(February 1) New Moon: The new moon is the first phase of the moon, during which the Moon and the Sun have the same ecliptic length. At this stage, the lunar disk is invisible to the naked eye, but it may appear to be present because it covers the stars behind it.
(February 16) Full Moon: The full moon is the phase of the moon in which the Moon appears to be fully illuminated from the Earth's perspective. This happens when the Earth is between the Sun and the Moon. This means that the crescent of the moon orbiting the Earth - on the opposite side - shines brightly in the sun and appears as a circular disk.
(February 16) Mercury at Greatest Western Elongation: The highest peak occurs 22 days before and after low contact with the sun. As seen on Earth, Mercury moves from east to west about three times during the year.
MARCH
(March 2) New Moon: The new moon is the first phase of the moon, during which the Moon and the Sun have the same ecliptic length. At this stage, the lunar disk is invisible to the naked eye, but it may appear to be present because it covers the stars behind it.
(March 18) Full Moon: The full moon is the phase of the moon in which the Moon appears to be fully illuminated from the Earth's perspective. This happens when the Earth is between the Sun and the Moon. This means that the crescent of the moon orbiting the Earth - on the opposite side - shines brightly in the sun and appears as a circular disk.
(March 20) March Equinox: With the equinox of March, the Sun sets across the equator from south to north. It has been called the "celestial" equator because it is the imaginary line in the sky above the Earth's equator. If you are standing at the equator, the sun would move in a straight line on its way to north.
APRIL
(April 1) New Moon: The new moon is the first phase of the moon, during which the Moon and the Sun have the same ecliptic length. At this stage, the lunar disk is invisible to the naked eye, but it may appear to be present because it covers the stars behind it.
(April 16) Full Moon: The full moon is the phase of the moon in which the Moon appears to be fully illuminated from the Earth's perspective. This happens when the Earth is between the Sun and the Moon. This means that the crescent of the moon orbiting the Earth - on the opposite side - shines brightly in the sun and appears as a circular disk.
(April 22,23) Lyrids Meteor Shower: April Lyrids is a meteor shower that lasts from April 16 to April 25 each year. The light of the meteor shower is found in the constellation Lyra, next to its bright star, Vega. The highest amount of shower is usually on April 22 each year.
(April 29) Mercury at Greatest Eastern Elongation: The maximum angle (east or west) of Mercury is between 18 ° and 28 °, while that of Venus is between 45 ° and 47 °. These numbers vary because the orbiting planets are elliptical rather than completely round.
(April 30) New Moon: The new moon is the first phase of the moon, during which the Moon and the Sun have the same ecliptic length. At this stage, the lunar disk is invisible to the naked eye, but it may appear to be present because it covers the stars behind it.
(April 30) Partial Solar Eclipse: Solar eclipse occurs when part of the Earth is shrouded in a shadow cast by the Moon that completely or partially blocks sunlight. This occurs when the Sun, Moon and Earth coincide. Such alignment is accompanied by a new moon indicating that the Moon is close to an ecliptic plane.
