Horizintal green light beams shining from within small clouds -attracted by search lights from local town Randburg,Jhb ,South AfricaI had just come home early sunday morning from a nights outing. It was about 3:45 am doing exactly what I always do . That is to look into the morining sky and watch the stars.It was a slightly cloudy morning , standing in the drive way I could see the usual search lights lighting up the clouds just above it. To my surprize I noticed green light ray breams shining from within the clouds. I took another good look to confirm my sighting. There was scattered clouds nearby the clouds were the search lightup. From within a few clouds( about 4 or 5 ) these green beams where shining towards the search light beams in a "on" and "off" mode .It would lightup for a quick 1 second or a slightly longer , 2 to 3 second ray of beam pulse. No pattern that i could determine. I could not see any object or hear any noise to suggest a space ship(several small ones) as the beams came from within different patches of clouds ,shining horizonatally towards the reflecting cloud the was light up by the search light in Randburg,Johannesburg,South Africa. You could determine a forward or backward motion of the light as you could see an intense green light from what would be the source and a fading light of that beam ,being away from it . The angle from which I could see this event allowed me to see the change of direction of the beams from the different small groups of clouds . Just to ensure that this was not my imagination and to have a witness .I got my mother out of bed, after a few minutes later ,assuring myself that this is true and real to my senses. She to had seen the green lights shine from within the clouds too. It seamed to me that these crafts took cover within the patches of clouds. The beam lengths could not be more than 100m in lenght ,shaped more like a rectangular wood beam. The green beam lights would shine at that lenght and less depending if it was a bright or gentle beam (it varied for each small cloud group)...I watched this for about 20 mins...it was still there when I continued my way to my bed.
