Skywatch Line for Friday, April 22, through Sunday, April 24, 2016

This is Dudley Observatory’s Skywatch Line for Friday, April 22, through Sunday, April 24, written by Sam Salem.

On Friday, the Sun rises at 6:02am and sets at 7:47pm. The full Moon occurs at 1:24am on Friday. The full Moon that appears in April is called the Pink Moon. This name came from the herb moss pink, or wild ground phlox, which is one of the early spring flowers. It is also known as the Sprouting Grass Moon, the Egg Moon, and the Fish Moon. Early Colonial Americans used these names as they learned them from the local Native Americans. These names usually describe some activity done by those tribes during that time in their location as they used to track the time by observing the seasons and lunar months.

The Moon rises at 8:17pm on Friday, 9:13pm on Saturday, 10:09pm on Sunday.

Full Moon is out all night at the peak of this year’s Lyrid meteor shower. The annual Lyrid meteor shower is active each year from about April 16 to 25. This year the peak of this shower, which tends to come in a burst and usually last for less than a day, is expected to fall on the morning of April 22nd under the glaring light of the full Moon.

Mercury remains well-placed low in the west-northwest in twilight, but it’s fading fast.

On Sunday, around midnight watch Saturn and the red supergiant star Antares follow the waning gibbous Moon and Mars over the southeast horizon

Look high in the West for Pollux and Castor lined up early at night. The heads of the Gemini twins, Pollux and Castor, form the top of the Arch of Spring. The two ends of the Arch are Procyon to their lower left, and brighter Capella farther to their lower right.

Arcturus is the brightest star in the east. Spica shines to its lower right. To the right of Spica is the four-star constellation Corvus, the Crow of Spring. It is recognizable for its compact, boxy shape. In Greek mythology, Corvus was seen as the cupbearer to Apollo, god of the Sun.

Friday is the Earth Day. It is an annual event celebrated on April 22, on which day events worldwide are held to demonstrate support for environmental protection. It was first celebrated in 1970. While the Earth Day was first focused on the United States, it is now coordinated globally and celebrated by more than 193 countries each year. There are many ways to celebrate the Earth Day. You could plant a tree, make a meal with locally grown vegetables, clean up trash in the neighborhood, or save power.
