Summary : a bright object follows 2 women home and gives a show

My sister and I were heading home from work to her house,when we saw a very bright object out the passenger side window.it looked like a small sun and was heading in the same direction as we were which was east. We were on a straight country road and the object kept pace with  us.When we turned north the ufo turned north also.As we pulled into my sisters driveway we were facing east again and the ufo was over her backyard. We walked to the back clutching each other in an arm lock and standing in awe we observed it hanging motionless in the sky.It seemed to be putting on a show just for us because it split in two parts and then three forming a large triangle in the sky overhead.Each time it split it became as brilliant as the first object.There was no noise detected . All the objects started to rotate in the sky keeping the triange shape. We kept asking each other "Did you see that?" Finally the objects moved slowly off to the south and disappeared. We had a house full of peo! ple inside and we were so much in shock that we didnt go to the window and tell them to come out and see. My sister had a better encounter but that is her story.
