Photos taken from Ponte di Rialto, facing southwest. Two sets of photos were taken using continuos mode; both sets were seconds apart from each other. I listed that i captured 2 UFOs, but i am not certain that they are distinct; from the photo sets it seems they are 2 different UFOs, but there was a gap of greater than ten seconds between each set, so i can't be certain. The first set contains four photos, the second set contains seven photos. I believe i took the photos on 7/18/12, but it may have been the 17, 19, or 20.The UFO in the first set of photos appears to be a white, glowing, chevron craft tumbling in flight while traveling in a straight trajectory.The UFO in the second set of photos also appears to be a white, glowing, chevron craft tumbling in flight while traveling in a straight trajectory. The second UFO appears to be traveling in a parallel direction with the first UFO that traversed the sky before it, but the smaller apparent size of the second craft, and the lesser apparent area of the sky traversed indicate to me that the object was significantly further away from my position, though of the same type and actual size.NOTE: I WAS NOT ABLE TO UPLOAD THE LAST IMAGE OF THE SECOND SET DUE TO THE 10 FILE LIMIT, i'll attempt to add it after my initial submission. I'm referring to a file called DSCN2848.JPG
