an object with no clear shape, travelling fast, low, silent, with a very bright light/glow that appeared out of nowhereThe first light approached rapidly and absolutely silently from a South Westerly direction travelling in a North Westerly direction. We watched it pass right over head and it had no obvious shape - just a ball of light with nothing flshing, no exhaust, just very bright. We wondered what it could be for several minutes and then when we turned round, another one approached from the same direction with all the same charateristics. The passing of the two balls of light took about 10 minutes.
