While shooting the mountain range of area 51 on june 11 2020, at 9:43pm from black mail box, which is about 10 miles to the bald mountain range. i notice a single light heading at a slight angle upward. i got 4 images before it dissipated. my settings were f4.5 10 sec exposure, iso 2000, 38mm using a 120mm lens, nikon d750. i am submitting this because i have 2 issues with the 4 images. now they are in order as i shot them. it appears the craft in question is headed outbound from area 51 mountain range, as you can clearly see bald mountain on the far right. my contention is that, although it appears to be a satellite,,,but not in all frames.. the first 3 frames all have tails.. like a shooting star, the 4th frame has a satellite profile which means its one straight line. my other contention is,, a shooting star i think not, if it was a shooting star it only last a few seconds, not a full minute, a satellite with a trail? nope. i will label the frames, and the worst part about these photos, is that the tail is going in the wrong direction, you would expect the tail to be trailing,,if a object is headed upward... in these photos the tail is forward. the camera is not upside down, nor are the images are. but i be glad to hear any explanation of these photos. each photo is 10 seconds long. i have included the zoom image, just to save everyone a lot of time at home. good luck mufon.
