Location: approximately 6 miles south of quartzite arizona near hwy 95. i was camping in the desert. date: january 23rd,, 2018 time: local time of 19:37. the iss was due to pass overhead and i set my camera on a tripod to record it's passing. the iss path was going to transverse the moon and i thought it would be an interesting photo showing the path. i set my camera on a tripod and took a couple of 10 second exposures to show the iss path. when the iss got to the moon, i exposed for 10 seconds and recorded the moon with the iss transversing. i later downloaded the images and this particular image showed something in the photo that i can not explain. i did not see the object directly. i did not know anything was there at the time the photo was taken. the sky was dark and clear as evidenced by the visible star field. there is one other object showing in the photo in the upper right hand corner. i believe this to be a passing satellite. there was nothing in the area that would have been tall enough to be in the photo as it was high in the sky. the camera was a nikon d4 with a 24-70mm f2.8 lens. 24mm, f2.8, iso 1600 set for 10 second exposure. the original image is in raw format and submitted as .Jpg. no other post processing has been done. i am an experienced photographer and have taken many photos with low light, high speed films etc. over the years. if not a reflection of some sort, i have no explanation of what it is but it is unique. this was a 10 sec. exposure so the object would have had to remain still for that amount of time to show up as it is.
