1. near trump towers in mecidiyekoy istanbul turkey. i was hurry to catch a public transportation. the date and time was locally 28th of december 2019 at 7:01 pm according to my mobile device's time stamp. the sky was a bit cloudy . 2. it was a sudden decision to look in to the sky. i mean no reason for that action . 3. first i thought that it was some kind of human made entertainment light shows etc. but i did not see any evidence of any sources coming from . 4. the objects moved arbitrary pattern in clouds. the speed or movement of objects could not act like an any drone . i observed for a short time since i had no time . for that short period of time the objects moves like a circle within an area and sometimes near side area other same objects were jointing and then moving like a pattern for a while. some objects left to other near area. but i could say that they moved in groups not any sole movement at all . 5. i wish i could stay there for a longer period of time for observation and i wish i had time to take long time and better quality of a videos and pictures . i feel a bit shocked but i had to move on on my way. so i guessed that this phenomenon continued for a while ! i decided to share this with this platform for understanding such things via all kinds of analyses and conclude with an explanation within scientific methods . we should know the truth about such things whether or not belongs to a natural phenomenon or not . as you may see the gps coordinate and time can be retrieve from my video file. i have not touched or edited the video. 6. as you can realized that i left the place for my reasons so i cannot say about disappearing the objects from my side .
