Early dusk around 7:20 pm et, observed either a sphere shaped object or the bottom of a perfectly round object, several times larger than any star or planet but much smaller than the moon, moving very slowly, almost hovering, traveling from nw to ne. got my binoculars first and viewed it. immediately realized needed to get my camera and large telephoto lens. took numerous photos. the object had highlighted horseshoe shape arcs at top and bottom of sphere. center area dull or darker with two highlighted horizontal curved streaks located near the lower arc. these details were not visible with the naked eye. but you could see a difference with your eyes as the sky got darker. succession photos showed these streaks to change position. as the sky got darker, the sphere or round object became more defined. the streaks and arcs edges were more defined. no exterior lights or sound. i briefly stopped watching it to position myself for more pictures, looked up and the object was gone. could not find it anywhere. the sky had some clouds move into the area, but were not dense. object still should have been somewhat visible. whole incident lasted approximately 20 minutes. when looking at the pictures, the object was slowly hovering/moving from left to right. i have 40 pictures.
