We saw 6-7 craft move from SE to NW, with very bright orange/yellow lights and no sound.At about 19:10 on February 11, 2012, my husband was looking out our bathroom window when he saw the first of these craft. The craft came from the South East and were heading North West. Another craft came about 30 seconds later. There were 4 that moved past our house spaced very evenly apart, and about 30 seconds from each other. Then there was a pause and two more came into view and then went past us.I went to get the binoculars and during that time one and possibly two more passed over.Each looked exactly the same. A bright orange and yellow light that flashed on and off. With the binoculars we could only see the lights no shape at all.The really amazing thing is that there was absolutely no sound as these craft passed over us. We had the window open and we live in a quite area with little traffic etc. There was no sound.
