Standing on the deck facing SE appears nearly every night the same unknown flying object. Oval in shape it will stretch and thin to half moon or into a bell shape, moving up or down left or right horizontally in any direction, slow and fast speeds stop instantaneously. Hover in one place, fade to a small spec and come into view and seem to multiply its original size by 10x, constant color change, colors seem to sporadically move across the mass, very bright to dim, has mass that just seemed to eject from it, also have seen mass that seemed to be absorbed,amazing and intriguing. Ive been watching it for nearly a year, almost every night it appears in the same area in the sky. It seems to just move out of view, other times it fades untill its just a tiny spec then gone. And can appear the same way. I do not have the equipment to record or photograph it properly. Have tried and its too dark and too far away for the camera on my phone. I believe with proper equipment this would prove to be a very insightful and educational experience, especially since the object appears nearly every night.
