For astronomy enthusiasts, the night of July 27 to 28 is exciting announcement as a total lunar eclipse lasting 1 hour 43 minutes – the longer of the century – can be observed. But what can be a shock absorber for the city is a cloudy sky that could make visualization difficult, experts say.
The Department of Earth Sciences has announced that the partial eclipse of the moon will begin at 23:54 on July 27 after which the moon will gradually be covered by the shadow of the Earth. The whole phase will start at 1 am on July 28th and the total lunar eclipse will last until 2h43. After that, the moon will begin to emerge from the shadow of the Earth and the partial eclipse will finally end at 3:49 am on July 28th.
Explaining a total lunar eclipse, Dr. Arvind Paranjpye, the director of Nehru's Planetarium said during such an event, the sun, the moon and the Earth are on a nearly straight line with the moon being in the total shadow of the Earth or in its shadow region.
"The moon will be in the penumbral shadow of the Earth at 10:53 pm in July, 27 and nothing will be visible to the untrained eyes for the next 30-40 minutes, after which we can see a gradual change in the brightness of the lunar disk At 23:54, the moon will be in the shadow of the Earth's shadow and the black shadow will progress on the lunar disc, covering the crater through the crater of the moon. This will be visible to the naked eye.In the next hour, the moon will be completely in the shadow of the Earth.At this moment, the color of the lunar disc will be red with its many shades, "said Paranjpye .
He added that another celestial event will take place the same night. The sun and Mars, the red planet, will be opposite each other with the Earth in the middle, so that Mars is getting closer to Earth and appears brighter than ever. Although the events are exciting, the experts have a word of warning.
"Do not be too excited. Since we are in the middle of the monsoon here in India, the sky is likely to be cloudy. Thus, those who expect to see the surface characteristics of Mars could be disappointed even after using a telescope. In case of eclipse too, the viewing would be difficult but as the window is longer, people might hope to see something, "said Paranjpye
Authorities of the Interuniversity Center for Astronomy and Astronomy. astrophysics (IUCAA) and private astronomy clubs.They said they were not sure to organize viewing events because of the monsoon.Sammer Dhurde, science educator and astronomer at the IUCAA, confirmed that "because of the cloudy sky, a viewing event has not yet been planned."
Sagar Gokhale, secretary of Jyotirvidya Parisanstha, who is the most former group of amateur astronomers of the city .: "It will be exciting to watch it and usually it can be seen with the naked eye, although we also have a few telescopes to watch. However, due to the monsoon, the sky is cloudy and, therefore, viewing is unpredictable. It's only closer to the date we'll know, although usually, few viewing events are organized right now.
However, Paranjpye said that those who want to see the phenomenon should not lose hope .. will organize a live webcast. "Details will be announced on the website closer to the date", he said.
