Blood Moon 2018: The sky is likely to be cloudy due to the ongoing monsoon season. (Representation)
The lunar eclipse of tomorrow will be the longest of the century and planetariums across the country have made elaborate arrangements for hobbyists, but rains and skies cloudy are likely to play a spoiler.
The eclipse will also coincide with Mars' closest approach to Earth. Nehru Planetarium in the nation's capital will hold a "Carnival of the Moon" tomorrow.
N Ratnashree, director of the Nehru Planetarium, said that in addition to organizing five telescopes, the center also organized lectures on the eclipse. Amateur astronomers have also volunteered to guide people tomorrow about the eclipse, she said.
"But all this is subject to rain and cloudy skies, there is already a lot of enthusiasm among people". The Astronomical Society of India (ASI) has warned against creating a hype around this event.
"For serious astronomers, this event offers an extraordinary opportunity to study Mars through their telescopes." We are in the middle of the monsoon here in India, the sky is likely to be cloudy ", he said in a statement
.The inhabitants of Jammu and Kashmir and Tamil Nadu are the most likely to witness the event, "said PTI chairman Aniket Sule Awareness and Public Education Committee (POEC) of ASI
. Lunar eclipse will coincide with another relatively "heavenly phenomenon" known as the opposition of Mars.
M. Ratnashree said that the Moon would enter the Earth's shadow at about 10:53 am Noticeable nothing will be noticeable to untrained eyes for the next 30 to 40 minutes.After that, one can notice a gradual change in brightness on the lunar disc.
At 23:54, the Moon enters in the shadow of the Earth's shadow. The dark shadow will now be seen advancing on the lunar disc. This will be very visible to the naked eye
"At 1 am on July 28, the moon will be completely inside the Earth's shadow, at this time the color of the lunar disc will be red with many shades – crimson, red brick, etc.The maximum eclipse time is 1.51 hours, the total phase of the eclipse will end at 2.43 hours, it will be out of the shaded shade before 03.49 o'clock and completely out of the shadows at 5 o'clock in the morning to last 103.6 minutes, "says Ratnashree.
Mars will rise around sunset time and lie down around the time of sunrise. An opposition occurs when Mars is closest to Earth in its orbit, both on the same side of the Sun.
The red planet will appear brighter and larger than usual. Although March's opposition is tomorrow, it's getting closer to us on July 31st. This curious fact is that the orbits of all the planets around the Sun are not a perfect circle, but an ellipse.
from March to us will occur four days later than his opposition. This is also one of the reasons why the distance between Mars and Earth is not the same at every opposition.
The distance between Mars and Earth is between 400 million kilometers (2.7 Astronomical Units, or UA) and 56- million km (0.38AU). The closest approaches occur during the opposition.
This time, Mars is getting closer to the Earth than any other time in the last 15 years. As a result, it will also appear to be the largest and brightest in the last 15 years. At this moment, Mars will be only 58 million kilometers from the Earth.
In technical terms, the angular diameter of Mars seen from Earth will be more than 24 "and it will be brighter than -2.75 magnitude.
For comparison, the brightest star in the sky night, Sirius, will be about 3 times weaker than Mars that day and the average angular size of the moon is 1800.
Even at the closest approach, Mars will look small, it would take a telescope equipped with a lens or a mirror that is at least "
Nevertheless, it would be an exciting opportunity to see the bright red planet right next to the red moon (eclipsed) that night. d, s, id) {var js, fjs = d.getElementsByTagName (s) [0]; if (d.getElementById (id)) returns; js = d.createElement (s); js.id = id; js. #### # 39; facebook-jssdk;)); 59008]
