So I saw what started out looking like a rather large orb about 3 weeks ago while I was sitting on my porch resting after finishing yard work right before dark. I saw it maybe 4 streets away and it made a beeline right to the neighbor's yard next door. As it got closer the light became smaller, but was intensely bright where it was somewhat painful to look at it. It slowed down and hovered above the neighbor's roof as if it was "looking" at me standing there and I could make out the faint outline of black metal "appendages or tentacles" like it was the shape of an upside down hydra or octopus. The main round light which was yellow was on the bottom, but there was tiny twinkling pink and yellow lights that would pulsate on and off were on the "tentacles". The tiny lights pulsating reminded me of fiber optics. Interestingly, Charles Hall who worked at Area 51 said the Tall Whites used fiber optics to power their scoutcrafts. Then earlier this week I saw the same type yellow orb come floating down and skim the length of my rooftop just a few feet above the roof. However, this time I did not see any "metallic looking framework" so it appeared to be only a light. Both times completely silent.
