I was at Po'olenalena Beach, Wailea, Maui photographing a couple after their wedding. I did not see the object during the photo session but after reviewing my files I saw a pyramidal shaped object in 2 frames. The object was brighter than the sunset sky and white in color while clouds showed warm hues of sunset. The frames show some sort of dark trail behind it, exhaust?? I've attached the full frame file and a detail from the two frames containing the craft. I have been a commercial photographer for 45 years and currently I work w/ the UHawaii Institute for Astronomy at the TLRS4 laser ranging site on Haleakala. I am an observer for this system doing day and evening shifts. I have seen aircraft at many distances while at my post but what I photographed is unknown to me.
