Originally a flash or streak traveling extremely fast traveling south to north. The craft came back and followed us for about 10 miles

We were in a car traveling west. First a streek across the road traveling very fast so fast almost not noticeable. About 5 minutes later after we discussed what we had both witnessed it returned ,slowly rising above the treeline. The shape was like an orange moon rising. The craft started to pulsating slowly dim orange to bright orange slowly . I was watching it in the rear view mirror and said to the passenger what is that ? He crawled into the backseat and studied closely for about 7 or 8 minutes from rear window and we dicribed what we saw to each other. I hit the break lights 2 times the craft flashed 3 times completely dark between flashes and instantly disappeared. It seemed to go streigt up kinda due north at an unbelievably fast rate of speed. At this point we had slowed to about 30 miles an hour ,as it disappeared a semi truck and trailer came barreling around a corner lots of bright lights kinda shocking us.
