five large orange orbs silently moving across horizon low in the sky

I thought I should report this for my friend, just so it can be documented.
They were camping on south shore of Lake Erling, Ar, cooking dinner about 9pm when his son started yelling for him to come look at this weird light through the woods.  He said it was about 100 yards out and huge round orange orb moving across horizon, low in the sky.  Then another, then another, five total.  The son said they seemed to be spinning and have an unclear whitish glow on the bottoms of orbs.  My friend didnt have his glasses on so could not see that clearly. TOTALLY silent. Their movement was towards Taylor,AR (looking north). The orbs lit up the sky around them.
