I have been looking through the photos that i took while on vacation in morocco and in one of these photos i have noticed an object in the sky above an building. i have taken 3 photos in rapid succession of the same scene, about 1 sec appart. the object was present only in second photo, which means that it was there for less than 1 sec, which means that it moved very fast. in large magnification of the photo it can be seen that it moved from left towards right. the exposure was 1/250 of the second.
