Bright orb seen moving slowly over lake and the picked up speed and disappeared.

I was lying on my couch which has a large window that faces a grassy area and then a small lake.  As I was watching TV, I caught a small orb out of the corner of my eye.  It was high above the lake and moving downward.  
At first I thought it was a shooting star, but it was moving too slowly and the orb stayed circular and appeared to have a haze around it.  As it got closer to the tree line across the lake, a round red light appeared at the bottom of the orb (but was not flashing).  The orb then started moving very quickly before disappearing.  The whole incident lasted about 7 seconds.  I am certain this was not a shooting star or aircraft.
