I was taking some pictures of a beautiful sunset with the Boston City on the background. I was near Constitution Beach exactly on Bayswater St. in East Boston, MA.
I took 14 pictures total of the sunset on Saturday, February 20 2016 at 5:10 PM. When i got back home i showed the pictures to my wife and we notice a little object on one picture that caught are attention, at the beginning i thought that was dust on the camera lens of my cellphone but went i did zoom in on the picture to see close up we look our faces each other, we said... what!!! that looks like a Flying Saucer, we couldn't believe it. So we saw the next picture and that object was right there again but in a different place, we checked the rest of the pictures to see if we can find it in another pictures too. So the object it's on the first 4 pictures out of 14. Looks like the object is moving from the center of the photo it's on top of the sun also you can observe a halo on it (first picture) on the second the object is on the right hand side of the picture and the next 2 photos the object is on the left hand side of the photos. That happened probably in a lapse of time of 2 or 3 seconds between each picture. So checking the info on the photos all 4 were taken at 5:10 PM that day, so all that happened in the same minute.
