silver, disk shaped object with lights surrounding edge of underside, which hovered for about 15 secs.I first saw what seemed to be a disk shaped object appearing from over the top of my building (I live on the top floor of a 22 storey apartment block)and rotating in a northerly direction over the sea. A few seconds later I looked from a window in a southeasterly direction and saw a silver coloured craft, surrounded with lights (maybe 15 or so) on its underside, hovering over the apartment building next to mine. It hovered for about 15 seconds and then moved at extreme speed in a southerly direction.((NUFORC Note: Date is approximate. PD))
