On April 30 there is a second new moon. New York City is located in the Eastern Daylight Time. Though it bears no relation to eclipses, it is sometimes called a black moon.
Whether one sees two new moons or the inverse of that, two full moons in a given calendar month can vary, because moon phase times differ with one's time zone, and sometimes your local time means that your moon doesn't become officially new.
There are two new moons in New Yorkers in April and two in Los Angeles in March. The Mountain Time Zone in the U.S. will get two new moons in April.
Blue Moon: What is it and when does it occur?
New moons occur when the sun and moon are at the same latitude. This position is also called a conjunction. The moon is between the sun and Earth.
Unless the moon passes in front of the sun and creates an eclipse, new moons are invisible. In this case, we get a partial eclipse, in which the moon covers a portion of the sun, but it won't be visible to observers in North America. The partial eclipse will be visible from as far north as the southern half of the country, but only a small part of the sun will be covered. The best place to view the eclipse is out at sea, the last half of the eclipse will be after sunset.
Ushuaia is the largest city close to the eclipse center. The end of the world is what the local tourist authorities call it and the eclipse will start at 4:46 p.m. local time on April 30. The maximum eclipse will take place at 5:57 p.m. The sun sets at 6:07 pm when the eclipse is still going on. The sun is well below the horizon as the eclipse ends.
The eclipse will begin in Concepción, Chile, at 4:21 pm local time. In the northwest, the sun will be at an altitude of 18 degrees. The moon will cover about half of the diameter of the sun during the eclipse. In Ushuaia, the sun sets at 6:07 p.m., which is before the eclipse ends.
Four planets will rise in succession in the predawn sky on April 30. New York City will be the first to rise at 3:01 a.m. Venus and Jupiter rise at 4:18 a.m., followed by Mars at 3:47 a.m., according to In-the-Sky.org.
The two planets will rise at the same time later that day. Half a lunar diameter, and will approach within about a quarter of a degree of each other. While the predawn rising will be well before that the two planets will still be quite close, looking like a double star. Venus will be about 11 degrees above the horizon.
When the two planets rise, the moment of conjunction gets closer. In Tokyo, the two planets rise at 3:01 a.m. On May 1, Japan Standard Time will be at 3:42 a.m. when Venus and Jupiter will be above the eastern horizon.
The sun rises in Miami at 6:44 a.m. local time, where the trio of planets moves higher. Venus and Jupiter are 17 degrees high by 6 a.m.
The planets will all appear higher in the Southern Hemisphere, making a line from the horizon to the zenith. When the two planets rise at 3:58 a.m. on April 30th, it isn't visible from Cape Town. The planets rise before sunrise in South Africa, but it takes until 7:21 a.m. to see them. When the sky is getting light enough that the planets fade, Venus and Jupiter will be nearly 36 degrees high.
There is a conjunction in Melbourne at 4:42 a.m. The planets will be 14 degrees above the northeastern horizon on May 1st. Venus and Jupiter can get high in the sky before the sun goes down, because the sunrise in Melbourne is not for more than three and a half hours.
The sun sets in New York City at about 8 p.m. at the end of April. The sky gets dark enough for stars to come out at 8:20 pm when civil twilight ends and nautical twilight begins.
By 9 p.m. One can see the Winter Triangle in the west. Betelgeuse will mark the shoulder of Orion to its right and below it will be Procyon, which will be in the southwest.
As the constellation sets, one will be able to see the bright star in Auriga, the Charioteer. Looking to the right, one can see the shape of the Queen, and then the shape of Perseus. The king's stars form a triangle with a square-ish shape attached to the bottom.
One can see the Little Dipper, which is rather faint, and the Big Dipper, which is upside down, if one continues towards the north. The two stars at one end of the bowl are Alpha andBeta Ursae Majoris. Polaris is the North Star. One of the stars at the back of the bowl will lead to a meeting with Regulus, the Lion. There are two bright stars in the sky. The front paws are represented by Regulus, while the tail is marked by Denebola. If one looks south, they will see the Virgin, the Virgin of the Universe, to the left of the Lion.
The handle of the Big Dipper can be used to arcs Arcturus, an orange-yellow star in Bo, the herdsman, and then to reach Spica. The Northern Crown, also known as Hercules, is rising in the northeast, just behind Bo.
In the south, sunset is getting earlier as autumn approaches. On April 30th, the sun sets at 6:12 p.m. local time in Buenos Aires, and at 5:34 p.m. in Melbourne and at 6:06 p.m. in Cape Town. In mid-southern latitudes, the sky will be completely dark by 7:30 pm. The Southern Cross will be high in the southeast by 8:00 pm on April 30. The Cross will be above the constellation Centaurus, where the bright star Acrux lies, and Alpha Centauri will be extended to the horizon.
One can find the three constellations that make up the ship, the Puppis the deck, the Vela the sail, and the Carina the keel, when moving upwards from the Cross. Canopus will be a full 72 degrees high at 8 pm in the middle of the night in Australia.
The Big Dipper in the Northern Hemisphere can locate north, but the Southern Cross can locate south. An imaginary line from the two brightest stars in the Southern Cross, which form the vertical post, extends it about four and a half times the length and drops a vertical line to the horizon. It is possible to locate it by using thepointers in Alpha andBeta. There are two stars in the constellation. One draws a line between those two stars and Achernar, the end of the River. The pole is marked by the halfway point of that line. There is no equivalent of Polaris in the constellation Octans, which includes the South Celestial Pole.
In the south, sunset is getting earlier as autumn approaches. On April 1st, the sun sets in Buenos Aires at 6:48pm and in Melbourne at 7:14pm. The Southern Cross will be high in the southeast by 8:00 pm when it is dark. The Cross will be above Alpha Centauri, which is also known as Rigil Kentaurus, and one can see it rising from the Southern Hemisphere. As one's eyes continue to move northward, one encounters Cancer and Gemini.

If one draws an imaginary line from the two stars in the Southern Cross, which form the vertical post, extends it about four and a half times the length, and drops a vertical line to the horizon, one is pointed south.
