It is tamilnadu and I live in tirupur city .On a usual night I was just enjoying the stars as it was bright.it was like 9.30pm.suddenly I felt like I m covered by a tent a large shadow appeared around me from no where around me when I saw straight up I could see a disk shaped space craft that had a light that snapped like a crop circle I ve seen before in google.it was illuminating and the surface wwas black and grey.it had a diameter of like 150ft it was huge and sounded a hmmm sound which was powerful.I saw it for about 1min and suddenly it ascended up by which the surface starting rotating in a great speed and in a wink the object was no more to be seen.
