4 bright lights moving fast and slow , making circles, sometimes above and sometimes next to each other.First I thought I saw a plane, but there where two. The lights were sometimes flashing and sometimes very bright. Then also sometimes you could almost not see them anymore and then suddenly they where very bright again. First there were two, but after about 50 minutes I saw 4 lights. They were going round in wide circles and left and right, sometimes they were above each other and then they were next to each other. Sometimes I thought I saw a red light (thats why I thought I saw just a plane), but the way these ufo's were flying was to stranges for a normal plane. And the light which flashed so bright was very stranges to. And when suddenly there were 4 of them (which I never saw before) and it looked like they were dancing in the sky.Sometimes they moved fast and sometimes very slow and sometimes it looked as if they stood stil in the sky.((NUFORC Note: We wonder whether the lights may have been part of an advertising display. PD))
