This is probably my 4th UFO sighting. And also the 4th one from the same location.Date: 19-Sep-2014Time: 19:22 (India Time)Sunset (Delhi time): 18:22 (India time)Moonset (Delhi Time): 15:18 (India time)Weather: Unusually very clear sky. Lots of stares were visible in the night sky.I arrived at the park at around 7:00 PM and sat on the bench facing North-East-by-North. The sky was unusually clear and quite dark because there were no clouds and hence no illumination in the sky due to the city lights. Since I have seen 3 Extraterrestrial Crafts from this location (park), I habitually kept looking at the sky. As I looked vertically up, I saw a moving star (not a shooting star). It was almost overhead, slightly to my right and was the same size and brightness as any other star visible in the night sky. It looked like and moved at the normal speed at which manmade satellites move across the sky and took about 15 to 30 seconds to traverse the sky from above the center of the park until I could see it no more.Since I have seen 3 extraterrestrial crafts from this very location earlier (58769, 65065, 65067), I feel there are 50% chances thatthis too is a UFO and perhaps is my 4th sighting.My 3rd sighting (65067) was a 100% Extraterrestrial Craft 11 days ago and that makes me think this too was a UFO. I have been going to this park regularly and I haven't seen any other manmade satellite neither form here nor anywhere else in Delhi in that past few years. There are a lot of suspended particles in the Delhi air (pollution) which reflect the city lights, which makes seeing manmade satellites in the sky almost impossible.I repeat, based on very recent previous sightings, there are 50% chances that this is a UFO.
