Ball of fire travels at steady speed across the sky.I observed the object moving from south to north at a constant speed. The object did not appear to be floating or falling. The object appeared to be approximately 300 to 500 feet above our heads. It was basically round in shape but did appear to slightly change form. It was an amber colored object that appeared to have subtle changes in its hues. After it traveled north for approximately two minutes it changed direction and then traveled up and directly away from us. I could tell it was moving away and not standing still as it slowly got smaller until it disappeared. It appeared that the object never changed speeds nor did it appear to be affected by any wind or air currents. None of us heard any noise emitting from the object.
