red glowing object in daytime sky

My half-sister and I were at the home of a family friend in our neighborhood.  Our neighborhood at the time was at the western edge of town.  This house was one of the homes on the edge of the subdivision.  Right behind the house are power lines with those tall towers.  We were in the backyard, clear blue sky, bright sun...my eye caught something in the western sky.  It was red, and as it made its way towards us, I could tell that it was maybe no larger than the house.  It was red, very red, like it was pulsating, as it had the bright blue sky as a background.  It had no reflection, I remember because I thought that it should since the sunlight was hitting it, any metallic object might reflect.  When it stopped above the power lines, about fifty feet above us, it was then when my half-sister saw it as well.  I remember that it just hovered, and seemed to make a dull low-throbbing sound.  As it hovered, my half-sister began to yell and ran inside to get our parents.  While I stood there, the object just hung out, perhaps moving ever so slightly.  It seemed to be looking at me.  Then just as my half-sister came out, the object zipped a bit to the sides, and then shot straight up and disappeared. No trails, no sounds.
