Here’s a quick look at what’s going on in the sky during the month of April, 2013:
April 3— Last Quarter Moon, 12:37 a.m. One-half of the Moon appears illuminated by direct sunlight while the illuminated part is decreasing.
April 10— New Moon, 5:35 a.m. The Moon is not illuminated by direct sunlight.
April 15— Moon at apogee (its farthest point to the Earth), 10 a.m.
April 18— First Quarter Moon, 3:57 p.m. One-half of the Moon appears illuminated by direct sunlight while the illuminated part is increasing.
April 20— Astronomy Day.
April 22— Lyrid Meteor Shower. 2013 is expected to be an unfavorable year for viewing this normally moderate shower.
April 25 — Full Moon, 3:57 p.m. The visible Moon is fully illuminated by direct sunlight. Though the Moon is only technically in this phase for a few seconds, it is considered “full” for the entire day of the event, and appears full for three days.
April 25 — Partial Eclipse of the Moon. This will be a very minor partial eclipse, with the Moon’s uppermost limb merely grazing the Earth’s dark umbral shadow. At mid-eclipse, only 2 percent of the Moon’s diameter will be inside the dark shadow. The Eastern Hemisphere (Europe, Africa, Australia, most of Asia) will have the best view. This eclipse will not be visible from North America. Moon Enters Penumbra: 2:02 p.m. – Moon Enters Umbra: 3:52 p.m. – Middle of Eclipse: 4:07 p.m. – Moon Leaves Umbra: 4:22 p.m. – Moon Leaves Penumbra: 6:13 p.m.
April 27 — Moon at perigee (its closest point to the Earth), 1 p.m.
April 28— Saturn at opposition. A body in space is at opposition when it sits 180° from the Sun in relationship to the Earth. This is the best time to view a planet.
