I was sitting outside my balcony on may 22 around 8 to 8.30 the sun was going down . it looked very beautiful i always take pictures of the beautiful sky. but this time it was different. first of all i am on the 29th floor highest floor in my building . i was looking at the sunset go down . then took a couple of pictures. i was shocked what i did not see but was on the picture. so i blow it up and couldn't believe what i saw. it was shaped like a ufo half a disc with and darker line in the middle of this . it looked like a inside down cup and the bottom was a different color line in the middle the bottom of what ever this was look like a flate plate upside down but all in one. i have never seen anything like this before. i have a picture.
