Red light in sky, in evening, stayed in place for 15 to 20 minutes.

It was the evening and I was returning home.  Upon returning home I noticed a red light in the sky at the end of the street.  It was a dead end street, and we lived in the boondocks!!  It was dark and the light just hung in the sky.  I watched it for some time, then went into the house and got my brother in-law and mother.  We watched for some time, then my brother dismissed it as a plane.  It did not move, it stayed in one spot.  I do not, to this day, believe it was a plane.
Witness indicates that the date of the incident is approximate.  PD
