I was taking pics of the moon which i do often. there were clouds but sperradic and i like the effect clouds have in front of the moon. when i saw these sphere like shapes two maybe three crossing path of moon from right to left. i observed moon for about an hour..Really don't know how long they were there i did not notice them really till they were starting to cross in front of moon.. i thought maybe a cloud or a drone but it was way to high and seemed to have a solid form.
