red light changed to yellow .3 others lights moving very fast(1 yellow and 2 red)I live in Lód (??) in Poland. At about 22:50(Polish Time), my sister saw a light on West and told me that. It was really strange, red light.There weren`t much stars on the sky.This light was lower than stars. It was moving very slowly (slower than planes) to the South-West direction and stopped sometimes. Suddenly it dissapeared and turn up back, but now it was very weak yellow light.In 20 seconds it changed to very strong and quite yellow circle light. After about 1 hour I called my friend.He saw the same light from his house. Suddenly near that light flight very,very fast other circle light (similar to comet) but turning 3 times.It was very strange.It made shape on the sky like thunder but it wasn`t thunder for sure.It was yellow light moving very fast.After that we saw 2 others red lights. They were smaller and red. They were moving very fast around themselves, and made shape similar to number "8". Sometimes they were moving away but returned after a few seconds.We obesrved that objects for about 5 hours( 3 hours non stop).There aren`t any military buildings and objects nearby. In our opinion it couldn`t have been plane(to strong light and moving too slowly),comet,or ballon. First I thought it was "circle thunder" ( I don`t know how to say in English) or Venus, but these moving lights...It could be UFO. Only one is sure it was very exciting((NUFORC Note: We are uncertain about the town in Poland in which the alleged sighting occurred. Several characters in Polish did not translate to English well, so we assume the city in which the sighting occurred was "Lod," Poland. One of two sighting reports submitted apparently by the same group of students. PD))
