winter nite wonder

The black top I was traveling was and still to this day is elevated 5ft. above the fields.Around 20:00 hrs (8:00 p.m.)Heading north,on my left side,i noticed a ball of fire grow from out of no where into a beatiful redish/orange color that intermixed with in itself.This energy/fireball glowed but did not light up the ground or area .This wonder stayed exactly to my left and same speed as i was driving(60mph).It stayed at this beatiful intentness and colors for 10 seconds max.,then dissapeared (went out??) as fast as it appeared.After maybe 6-7 seconds,to my supprize,again the same occourance happened as the first mentioned above.This time the brightness and color hit the same max as before for about 2-3 seconds-then intensified way beyond anything i had ever seen before,but could look at it. As i was thinking,just how big and bright will this thing become,it left at a rate of speed,that is not possible from anything on our earth.It went forward and up and out of sight in 2 seconds.Looking at it,the size would be compaired to a soccor ball at arms length.This object glowed redish orange.No actual structor was noticed.Just a intense beatiful color in a fire ball.Maintained with in itself.Nothing abnormal went on with the car.
