red/orange disk shaped light seen at dusk

Right as dusk was turning into darkness, my brother, my cousin, and I watched as a disk shaped object appeared across the woods from our house. 
Even though we were all kids, I the oldest being 12. my brother 10, my cousin 9, we were all very aware of the bright orange/red pulsateing disk shaped object, big as a football field, hovering above the trees just across our road. It hovered for approxmentally 5 minutes then seemly blinked out. Their was no sound and at the time of the sighting their was no traffic passing by on the heavly traveled highway we lived on. 
I ran into the garage to tell my parents to come take a look but they wouldn't as they were involved in a heavy dicussion. I do know my dad was having trouble with his power equipment working at that moment and I tried to tell him it was because of the UFO across the road. Then I ran back out to watch the UFO as I didn't want to miss it's departure. 
WE wern't scared, more so intriqued by it all. I didn't see any other people in the neighborhood witnessing this event.
