1925, observers lined up in Manhattan to measure the total solar eclipse.

Observers deployed by new york Electric Power Company stood on the roof of the west side of the city and recorded the total solar eclipse of1925 65438+1October 24th. At least one observer in each group will observe the solar eclipse, and the other will observe the approach of the moon shadow. (All rights reserved) During the total solar eclipse in new york, new york (United Gas Company) 1925, the street lamp was turned on and three women fainted. While selling smoked glass, vendors persuaded passers-by to "10 cents to save their eyesight", and seagulls fell into the water in succession. Suppose it's night, and 25 planes take aerial measurements. An airship sailed 8000 feet (2400 meters) above Long Island and watched the event. 149 the observer observed the upper Manhattan block by block to determine the exact southern limit of the sun. The solar eclipse came later than expected and became the front page of * * *. The following is the most spectacular solar eclipse in American history.

1On June 24th, 925, the solar eclipse crossed 96th Street in Manhattan. At that time, the temperature hovered around 9 degrees Fahrenheit (-12.8 degrees Celsius). The researchers went all out to measure this celestial event. Knowing the precise outline and orbit of the moon, we can accurately predict the time and path of the solar eclipse until the scale of the city block. But at that time, measuring the motion of the eclipse shadow on the earth was a key opportunity to accurately locate the size, shape and orbital path of the moon. The next day, an article in * * * wrote:

"Thousands of telescopes, telescopes, static and dynamic cameras are aimed at this sphere." The east slope of Mount Superior is dotted with tripod cameras. The Times article also said: "During the solar eclipse, people gathered on the dense radio antenna poles on the roof, and all kinds of theater glasses and eyepieces reached their eyes." It's about 4 seconds late to cover the sun.

Observers above 96th Street (square icon) in new york can see the solar eclipse, but they can't see it at a lower place (circle). (new york United Natural Gas Company) According to David Dunham, a solar eclipse researcher, a large-scale study conducted by new york Electric Power Company was conducted by 149 observers, which was dwarfed by the previous scale measurement work. 1878,

Dunham told Space Magazine: "The US Naval Observatory once conducted a total solar eclipse expedition, which covered Texas, Wyoming and Colorado." They made two expeditions, and the observer predicted the limit. But they were cheated, so they didn't get any information They did ask citizens in Texas and Colorado to observe and report to them, and they actually got some observations from this work ... but far less than the dozens of people who participated in this work in new york.

"There are also some problems in other past jobs," he added. "The main reason is the weather, which is not as large as 1925." . Dunham established the international occultation timing organization in 1975 to observe when celestial bodies pass in front of the sun and other stars. He also used the previous solar eclipse measurement data to analyze the change of the size of the sun with time.

Edison's 14 photographer is going to shoot the solar eclipse and any unusual phenomena in new york on124. New york observer (United Natural Gas Company of new york) is divided into two groups and three groups, which are stationed on the roof of 72nd Street to135th Street on the west side of Manhattan. According to the report released by the city's electric power company, at least one person will observe the shadow of the moon, and another person will observe whether the sun is completely covered by the moon. There are 25 planes to observe; Others can't take off because of the cold. Final statistics (US Air Force/Wikileaks Shared Resources).

It shows that many people in new york observed the solar eclipse, and found that it came a little later than expected, and the path of the solar eclipse was a little farther north than predicted by scientists. Therefore, we should teach researchers more about how the moon moves around the earth.

Careful observation of the moon's shadow "will make the next more accurate calculation possible," a reporter of * * * wrote.

Now, scientists know the path and outline of the moon with incredible accuracy, as well as the precise height of the earth at different positions, which enables researchers to predict the exact path of the solar eclipse. However, there is still a lot to know about the size and mechanism of the sun's external atmosphere, the so-called corona. According to NASA, the total solar eclipse occurred on August 2 1 day and August 20 17.

It may be the most concerned solar eclipse in history, because it spans the continental United States from coast to coast, and it will provide an unparalleled opportunity for research and cooperation between amateurs and professionals. The eclipse blockbuster project of the University of California and Google, as well as an initiative of the international occultation timing organization, called on volunteers from all over the country to record the exact location of the moon's shadow.

There will be no total solar eclipse in new york this time; Only a part of the sun will be covered. However, the people of the whole country will turn their eyes and instruments to the sun again, and this time, more cameras and telephones will be ready.
