Between 21 00 to 21 32, on 12-10-2015 in Hamburg, Germany, looking to the south between the stars altair and vega, me and my wife saw what looked like 3 stars traveling like 10 meters on the sky. It started very bright and while it were traveling the light was fading, the sky was very clear, no clouds at all, didnt look like an aeroplane(I would know if it was) and it came, the first one at like 21 oclock, 10 minutes after, came the second one and around 10 minutes after the third one. Always starting very bright and the light fading, didnt look like a comet, like burning gases but just a ball of light fading while moving. Didnt change the direction just moved straight.
