Lights above Eveleth Mn in mid 70's

I do not remember the exact date as asked.  I was 15-16 yrs old at the time, which would make it fall of 1975 -1976. I believe it was a weekend since I was out late. I had left Sib's, a place kids hung out and bought candy at,  had spent time plaing pinball, and rode my bike up Jones St. in Eveleth, MN which would be an easternly direction. A couple blocks away I had noticed a red light above the roof tops of the houses across the street which would be too the north. I cannot say how far the light was but it had to have been many miles. I realized it was moving slowly in a back and forth up and down fashion. For a while I rode back and forth on the street and finnally stopped to watch from the corner. If I remember correctly, the street corner was Jones and B Street. As I watched, a green Light emerged from the red and shot off to the east and soon after an orange light appeared and shot to the west. All I could do was sit there and watch it. About five or so minutes later, perhaps less, the lights came back. The green from the west and the orange from the east, not from where they shot to in the first place. The crafts then merged with the red light and the light shot quckly into the sky and disappeared. My experience with these things, ufo's and such, is emmence but for he most part I have kept it inside. My experiences began long before this and continue to this day even wih my moves to the Twin Cities and eventually to Pittsburgh
