Continued. had snowed earlier. on patio, no source of light seen until i looked up. saw dark object blocking sky with one round light bright white but did not reflect off patio or ground. completely silent and floating/gliding/moving slowly to west. as it moved west the sky was again visible. the ? back may have been flat. i raised my right hand to gauge size of round light..Distance was thumb to 4th finger. i watched several minutes, single light went dark as it continued west. i realized i was standing barefoot on patio in snow and returned to bed. my wife asked later in morning why i was up and on patio. i do not know what the object was, but i saw something i can not explain. f.Vaughan.
