Ufo was changing lights, from red to green/blue and yellow, was very very fast and was going one direction and coming back after a short break. to me it seemed it was quite far, but was moving much faster than a plane, in one sec it was on the other part of the horizon. then it stayed there for a little, showing only red light, went up a little, came down and came back to the starting point also very fast (few seconds). both me and my husband witnessed this event. unfortunately, we were so shocked that we have not made any video, considering that it was night too.
