According to the U.S. Naval Observatory, the new moon will occur at 1:55 pm ET (1755 GMT) on Saturday (October 14) and will be over the southwestern United States, southern Mexico, Central America, and northern South America. , mainly in Colombia and Brazil.
When does the new moon occur? moon passes between the sun and the earth. Approximately every 29.5 days, the Sun and Moon share the same celestial phase, an arrangement also known as a conjunction.Celestial longitude is the projection of the Earth’s own longitude on the celestial sphere – a line drawn due south from the North Celestial Pole near Polaris sun There is also a new moon.In this case, the sun and moon line up, and the moon passes in front of the sun, putting part of the Earth in its shadow, creating eclipse.
There are many types of solar eclipses. For example, there is a total solar eclipse, in which the moon completely blocks the sun.Another type is annular solar eclipse, where the moon appears slightly smaller than the sun; there is a halo around the edge of the moon. The reason a solar eclipse is different is that the moon’s orbit is an ellipse rather than a circle; the moon may be closer or further away from us than “normal” as it passes. Although the difference is small, it is enough to change the apparent size of the moon in the sky. Visually, a big difference between an annular and a total solar eclipse is that one cannot see the corona (the part of the solar corona) sun’s atmosphere) during an annular solar eclipse because the halo around the moon is too bright.
The 5 main phases of the October annular solar eclipse explained
Important note about Observing a solar eclipse: Always use appropriate safety equipment and never look directly at the sun through optical aids without an approved solar filter.Even if the sun appears dark (such as at sunset or sunrise), camera lenses, low-power binoculars, or spotting scopes, not to mention telescope, which focuses the light and energy from the sun onto your eyes. This can cause retinal burns and permanent damage to vision. The safest bet is to view the eclipse through specially designed filtered glasses or project the eclipse image onto a large flat surface set behind a telescope or binoculars. In general, if it’s not specifically designed for viewing daylight, don’t use it to view a solar eclipse.
For observers in the United States, Saturday’s eclipse will first be visible near Eugene on the west coast of Oregon. In Eugene, the moon touches the edge of the sun at 8:05 a.m. local time. Sunrise is at 7:25 am, so the sun will be close to the horizon. As the sun rises higher in the sky, the moon appears to touch the “top” of the sun and pass through it. The annular phenomenon – the moment when the moon is surrounded by sunlight – began at 9:16 a.m. and lasted 3 minutes and 55 seconds. The eclipse ended at 10:39 a.m. local time.
The path of the moon’s shadow will move roughly southeast across the continent. The annular solar eclipse will be visible from Winnemucca and Elko as it leaves Oregon and enters Nevada. In Elko, the eclipse began at 8:07 a.m. PDT and the annular event began at 9:22 a.m. and lasted 4 minutes and 18 seconds.The road then enters Utah, southwest of Salt Lake City; a good place to see it is Capitol Reef National Park, the eclipse begins at 9:09 a.m. MDT. The annular phenomenon occurred at 10:27 a.m. EST and lasted 4 minutes and 40 seconds.
The path of the eclipse also passes through the Four Corners Monument, where the borders of Colorado, Utah, Arizona and New Mexico meet. The eclipse begins at 9:11 AM MDT and the annular event begins at 10:30 AM and lasts 4 minutes and 40 seconds. The eclipse will be visible in New Mexico, from Albuquerque to Santa Fe. In both cities, the eclipse begins at 9:13 a.m. local time. In Albuquerque, the ring began at 10:34 a.m., and in Santa Fe, the ring began at 10:36 a.m. Albuquerque’s ring was much longer; 4 minutes and 48 seconds, Santa Fe’s 2 minutes and 45 seconds. The reason for the difference is that Santa Fe is closer to the edge of the shadow path; Albuquerque is closer to its center.
In Texas, the eclipse will be visible in cities such as Odessa, San Antonio and Corpus Christi. In San Antonio, the eclipse began at 10:23 a.m. local time and the annular event began at 11:52 a.m. and lasted 4 minutes and 21 seconds.
The next ports of call for viewing the eclipse will be the Mexican states of Campeche, Yucatan and Quintana Roo.At Chetumal, first contact (when the moon touches the sun) is at 10:51 a.m. local time, with a ring lasting 4 minutes and 21 seconds starting at 12:29 p.m.
The ring phenomenon can be seen across the entire northern half of Belize, as well as central Honduras and Nicaragua. In Costa Rica, a circular path passes along the Atlantic coast; a 1 minute and 18 second circular path will occur in Limon at 12:02 pm local time.
Later, the eclipse will be visible in central Panama and Colombia. In Cali, Colombia, the eclipse begins at 11:45 a.m. local time. The loop occurred at 1:31 pm local time and lasted 3 minutes and 40 seconds. In Brazil, the circular path passes through the northern half of the country, starting in the state of Amazonas and ending in the states of Paraiba and Rio Grande do Norte. In Natal, the eclipse track moved off the east coast of Brazil, with the eclipse beginning at 3:29 pm local time and the cycle occurring at 4:43 pm. Natal is located where the sun sets before the end of the eclipse; sunset will be at 5:13 p.m. local time, when the sun will still be partially obscured by the moon.

night planet
While the October 14 solar eclipse won’t be visible everywhere, the planets will be visible in the night sky. At the latitude of New York City, Chicago or Sacramento, Mars It will be very close to the horizon at sunset and disappear into the sun’s glare in the evening. However, around eight o’clock in the evening, saturn It will be visible southeast of New York City, about 32 degrees above the horizon, with sunset at 6:17 pm local time on October 14. The planet reaches its maximum altitude of 36 degrees around 9:37 p.m., scheduled for October 15 at 2:54 a.m. (Your clenched fist, held at arm’s length, covers about 10 degrees of sky.)
Jupiter It rises at 7:12 pm local time in New York, so the planet will be visible all night as it crosses the southern half of the sky. At 2:06 a.m. EST on Sunday (October 15), Jupiter reaches its highest point (called a meridian crossing or transit) at an altitude of about 63 degrees, which is about three-thirds of the way from the southern horizon to the zenith. Second position. The planet sets just after sunrise at 9:01 a.m. local time on Sunday.
Venus New York rises at 3:17 a.m. Sunday in the constellation Leo. It will be the brightest object in the predawn sky. By sunrise at 7:06 a.m., Earth will be 42 degrees southeast; if you observe it, try to see how far away from sunrise the planet will still be visible.
HGAt the same time, it is almost impossible to see because it is so close to the sun: at sunrise, the planet is no more than 3 degrees above the horizon, and the planet rises at 6:49 AM in New York.
For skywatchers in the Southern Hemisphere, the situation is slightly different because the sky is “upside down.” For example, Jupiter rises at 9:29 pm in Santiago, Chile (and at similar times at other mid-south latitudes) and reaches its highest altitude at 2:54 am local time on Sunday, when it is about 42 degrees (approximately from horizon to zenith half). Saturn rises in the afternoon (3:45 p.m. local time in San Diego), and by around 10 p.m., Venus is at an altitude of almost due north of 68 degrees. At the same time, Venus is at 4:00 a.m. local time in San Diego on Sunday. 56 and rise at sunrise (local time in San Diego). 7:01 a.m.) The northwest altitude of the planet is 24 degrees.
stars and constellations
Starting from mid-October in mid-northern latitudes, summer constellation The twelve constellations of the zodiac—Sagittarius, Ophiuchus, and Scorpio—are setting; At 7:30 p.m., Scorpio is mostly below the horizon, while Sagittarius is low in the southwest; The summer stars of Altair, Vega, and Deneb The triangle is located in the western half of the sky. Looking almost vertically upward, one can see Deneb, and if facing south, Vega to the right and Altair below both.Turn north and you’ll see Big Dipper Near the horizon, with the classic Big Dipper shape right side up (bowl facing up), one can use the pointers (named Cecil and Melak) to find Polaris, the North Star. Polaris is the brightest star in Ursa Minor, and the curve of the Little Dipper’s handle is easier to see if the sky is darker and away from city lights.
If one continues from the Big Dipper through Polaris, one reaches Caph, or Beta Cassiopeiae. Together with four other bright stars, it forms the “W”-shaped constellation Cassiopeia. Between Cassiopeia and Ursa Minor is Cepheus, king and husband of Cassiopeia.Cepheus and Cassiopeia were the legendary king and queen of Ethiopia, with Cassiopeia boasting that her daughter Andromeda She was even more beautiful than the sea nymphs and angered Poseidon, the god of the sea. In order to appease Poseidon’s anger, Andromeda and Cepheus were forced to sacrifice their daughter Andromeda to the sea monster Cetus, but Andromeda was ridden by Perseus. Rescued by Mapegasus.
In the evening, Perseus rises; if you look down along the “W” of Cassiopeia, the constellation is below Cassiopeia and just above the northeastern horizon.Looking from the base of the southern “W” of Cassiopeia (which would be to the right if looking eastward around 10pm), one encounters two long curves Star That was the emblem of Cassiopeia’s daughter Andromeda. If one follows the stars of Andromeda upward and to the right, one reaches the head of Andromeda, which is part of a group of stars called the Great Quadrangle. One corner of the square is the head of Andromeda, and the other three corners are the wings of Pegasus.
October 2023 Night Sky: What You Can See Tonight (Map)
As night falls, one looks down (to the east) in a corner of the Grand Place to see the constellation Pisces, or the Fish, as two long lines of dimmer stars forming a large “V” with two a smaller ring. Finish. However, Pisces is difficult to see from a city location because its stars are not that bright. At 10pm, the constellation Cetus appears above the horizon. The whale is often depicted as a whale, and its name is related to the word whale, which zoologists use to describe the order of mammals that includes whales, dolphins, and porpoises. Looking south (right) of the constellation Cetus, near the southern horizon, you can see Fomalhaut, the brightest star in the constellation Pisces Australis. Fomalhaut It is a first-magnitude star and one of the Sun’s closest neighbors, only 25 light-years away.
In the Southern Hemisphere, sunset becomes too late as the Southern Hemisphere summer approaches. In Santiago, Chile, the sun sets at 7:54 pm local time (the new moon appears at 2:55 pm local time).So the sky won’t really get dark until around 9pm observers will see Southern Cross It can be found low to the south-west, just below Hadar and Rigil Kentaurus, following the “spar” of the cross to the north (up from the horizon). Turn left and look southeast, and you will see Achernar, the end of the Eridanus River, about 37 degrees high.If you look in the other direction, to the west, you can see Antares, the heart of Scorpius (located below the horizon in mid-northern latitudes). Scorpio is “upside-down” – the scorpion’s claws point toward the horizon rather than upward, and its tail curves toward the zenith, forming a fishhook shape, with the end about 50 degrees above the horizon. Above Scorpio is the teapot shape of Sagittarius.
Looking north, you can see the Northern Hemisphere summer trianglebut with Altair at the top and Deneb and Vega at the bottom, near the horizon, with Altair and Vega forming a nearly vertical line, with Deneb to their right (east).
